1INTRODUCTION
1.1Definition:
Plant tissue culture is the technique of growing plant cells, tissues and organs in an artificial prepared nutrient medium under aseptic conditions. It aims to induce plant organs, or portions of them, to proliferate cells, each one of which may be regenerated into whole plants. These plants are replicas of the parent plant.
Gottlieb Haberlandt (28 November 1854) was the first scientist to plan for plant tissue culture and so he was popularly known as the “Father of Plant Tissue Culture.” He pointed out the possibilities of the culture of isolated tissues as Plant tissue culture. He suggested the potentialities of individual cells via tissue culture and also suggested that the reciprocal influence of tissues on one another could be determined by this method.
Plant tissue culture is widely used to produce clones of a plant by a methodknownasmicropropagation.Ithasbenefitedandadvancetheknowledgeoffundamental botany, especially in the field of agriculture, horticulture, plant breeding, forestry, somatic cell hybridization, phytopathology and industrial production of plant metabolites.
1.2 Applications of Plant Tissue Culture:
Micro propagation is widely used in forestry and in flori culture to conserver are or endangered plant species by multiplying them.A plant breeder uses tissue culture to screen cells rather than plants for advantageous characters, e.g., herbicide resistance/ tolerance.
1.3 Micropropagation:
The regeneration of whole plant through tissue culture is popularly called ‘Micropropagation’. This is a technique where a callus mass has been initiated from a single explants taken from any living part of a donor plant and within very short time and space, a large number of plantlets can be produced from such callus tissue. Again, it is possible to make a large number of callus pieces from the original stock culture during sub culturing.
1.3.1. Stages of Micropropagation:
- The process of micro propagation individually divides into five stages.
a) Stage0: Pre-propagation Stage
The pre-propagation stage requires proper maintenance of the mother plants in the greenhouse under disease and insect free conditions with minimal dust. Cleanen closed areas, glasshouses, plastic tunnels and net covered tunnels, provide high quality explant source plants with minimal infection.
Collection of explants for clonal propagation should be done after appropriate pre-treatment of the mother plants with fungicides and pesticides to minimize contamination in the in vitro cultures. This improves growth and multiplication rates of in vitro cultures. The control of contamination begins with the pre-treatment of the donor plants.
The choice of explant depends on the methods of shoot multiplication to be followed. All plant organs viz. bulb segment, inter-bulb segments, shoot tip, root tip. For axillary bud induction, callus culture, somatic embryo genesis explants bulb segments, internodes and leaves are collected.
b) Stage1: Initiation of Aseptic Culture:
In this stage sterilization of explants and establishment of explants were done. The plant organ used to initiate a culture is called explant. The choice of explant depends on the method of shoot multiplication to be followed.
- For micro propagation work the explant of choice is nodes
- For callus culture work the explant of choice is inter nodes and leaves.
- For somatic embryo genesis the explant is inter nodes and leaves.
c) Stage2: Multiplication of Culture:
This is the most important stage and the rate of multiplication determines the largely success of micro propagation system this can be achieved by-
- Enhanced axillary branching
- Adventitious bud formation
- Through callusing
i) Enhanced axillary branching:
The axillary bud present in the axil of each leaf either develops into a single shoot or form a cluster of shoots in the presence of cytokinin (BAP1.0 mg/l) in the medium.
ii) Adventitious Bud Formation:
Buds arising from any part other than the leaf axils or shoot apex are called adventitious buds. It is a standard horticulture practice.
iii) Through Callusing:
In tissue culture, the mass of differentiated cells commonly known as callus.
This either gives rise to shoot bud or bipolar structure resembling embryo (somatic embryo). This method is used when aim is to induce variability especially in self-pollinating species with narrow genetic base.
d) Stage3: In Vitro Rooting of Shoots
In-vitro grown shoots lack root system. For induction of roots, they were transferred to rooting medium. For rooting half strength MS medium supplemented with 1.0mg/l auxin was used.
e) Stage4: Hardening and Acclimatization of Tissue Culture Plantlets
This is the final stage and requires careful handling of plants. The transplantation from completely controlled conditions should be gradual. This process of gradually preparing the plants to survive in the field conditions is called acclimatization.
The plants produced in tissue culture, although green in color; do not prepare sufficient food for their own survival. Also, inside the culture vessels humidity is very high and thus the natural protective covering of cuticle is not fully developed. Therefore, immediately after transfer plants were maintained under high humidity. Optimum conditions were provided to plants in green house.
1.4. Advantages of micro propagation
Micro propagation has a number of advantages over traditional plant propagation techniques.
- The main advantage of micro-propagation is the rapid multiplication of plants that are clones of each other.
- Micro-propagation can be used to produced is ease-free plants.
- Growth manipulation: Nutrient levels, light, temperature and other factors can be more effectively controlled to manipulate the growth, multiplication and regeneration
- Micro-propagation produces rooted plantlets ready for growth, saving time for the grower when seeds or cuttings are slow to establish or grow.
- Round the year production: Micro-propagation is independent of season. As micro- propagation could be carried out throughout the year; production cycle can be scheduled to meet peak demands
- It can have an extraordinarily high frequency rate, producing thousands of propagules while conventional techniques might only produce afraction of this in number.
- It is the only viable method of regenerating genetically modified cells or cells after protoplast fusion.
- Micropropagation often produces more robust plants, leading to accelerated growth compared to similar plants produced by conventional methods – like seeds or cuttings.
- Some plants with very small seeds, including most orchids, are most reliably grown from seed in sterile culture.
2. OBJECTIVE
To establish a protocol for In vitro micropropagation of Aegle Marmelos , Moringa oleifera
Background
We chose Moringa for plant tissue culture because the lab work on problem based questions. In our case there was no problem but demand for the plants of Moringa using PTC practices. The respective farmer Mr Raghunath Shinde from Pabal ; had feild of Moringa and he observed that in his farm only few plants gave more production than other and he approached Vigyan Ashram for the Moringa saps ; thereafter we decided to practised on Moringa.
Another plant I chose was Aegle marmelos; which is woody medicinal plant for my eight semester READY program project .

3.1.1. Collection of Plant Material
Stem cuttings including the young leaf and bulb bud were excised from Moringa stock plant grown at Sahyadri Nursery, Astagaon. Tal-Rahata, Dist- A.Nagar.
3.1.2. Surface Sterilization of Explant
All inoculations and aseptic manipulations must be carried out in a laminar air flow cabinet. Before use, the working surface of the laminar air flow cabinet need to be cleaned by swabbing with 70% ethanol and switch on the UV light for 20 min. to reduce the chances of contamination. After that the regular white light is switched on.
The instruments like scalpels, forceps are sterilized by an alcoholic dip followed by glass bead sterilization inside the laminar air flow cabinet. Other requirements like bottles, conical flasks, cotton, distilled water etc. are sterilized by steam sterilization in an autoclave.
Leaves and petiole were removed from stem section and defoliated stems with bulbs were surface sterilized by tap water, 0.1% Bavistin, 0.1% Mercuric chloride (HgCl2) solution for 1 min. After pouring off the HgCl2 solution, immersing it in distilled water.
Explants were treated with following chemicals under laminar air flow.
- Washed multiple times with sterilized tap water.
- Treated with 0.1 % Bavistin for 10 min
- Treated with 0.1 % Mercuric Chloride for 1 min.
- Treated with 70 % Alcohol for 3 mins.
3.1.3. Inoculation of Culture & Incubation of culture
A piece of plant tissue explant is cut from the plant, disinfected i.e., removal of surface contaminant and placed on a medium. A medium typically contains Mineral salts, Carbon sources. Five initiation media having different growth hormone combinations were used in the present investigation. The objective of this stage is to achieve an aseptic initiation of culture i.e., without contaminating bacteria or fungi. The inoculated culture bottles were incubated at 25 ± 2 ºC temperature for 16 hours light and 8 hours dark per dayin 2000-3000 lux light intensity under cool fluorescent white light in the culture room.

Plant Tissue Culture of Lilium – We decided to take trials on lilium and Canna indica for comparative study of Banana .( Trials upto 24th of April)
Introduction
The white lily is a member of the genuine lily family of plants. The herbaceous flowering plants of the genus Lilium all have large, noticeable blooms and grow from bulbs which we used as explant.
The goal of the current study was to create cultural environments that would promote better shoot organogenesis from bulb scales. Additionally, the outcomes of micropropagation using segments of bulb scales are The majority of lilies’ natural habitats are located at high elevations, often more than 2000 metres above sea level. They are appropriate garden plants in a wide range of climates from temperate to subarctic latitudes due to their adaptability to extreme annual fluctuations in temperature and humidity
REFERNECE
Patil et.al., (2021) explained a procedure for its proliferation has to be developed because the plantlets’ ability to multiply by bulb is poor and they are more prone to disease. In this study, we looked at the effects of various concentrations of BAP and NAA on the germination of Lilium candidum shoots from bulbs as well as the effects of IBA, IAA, and NAA on these shoots.

Contamination after Subculture (after 6 days)
Discussion
- The aim of the present investigation was to optimize the culture conditions for In vitro micropropagation of Lilium
- For In vitro micropropagation of Lilium were efficiently used as explant for rapid propagation. Treatment of 0.1% Bavistin (10 min) + 0.1% HgCl2 (1 min) + 70% Alcohol gives the best results for sterilization of explant.
- The bulb segment of Lilium was inoculated on MS media containing 1.5 mg/l KN and 0.1 mg/l NAA for initiation showed best results of shoot proliferation. The similar observation were recorded by Patil et.al..
- The growing shoots were transferred in multiplication stage containing MS Media with 1.0 mg/l BAP and 0.2 mg/l NAA showed best results for multiplication. The similar observation were recorded by Patil et.al
Summary
The bulb segments were used as an explant for micropropagation of Lilium. Treatment of 0.1% bavistin for 10 min, along with 0.1 % HgCl2 for 1 min, 70% alcohol for 3 min and gives best result for sterilization of explants. These surface sterilized explants were inoculated on different hormone concentration for further regeneration and multiplication. The different media concentrations having KN, NAA (Control, 1.5 KN (mg/l) and Control 0.1, 0.2, 0.3, 0.4 NAA (mg/l) ) were used for the initiation of Lilium. Well grown newly formed shoots were transferred onto fresh media and primary explant was allowed to initiate newshoot growth. The media containing 1.0 mg/l BAP+ 0.2 mg/l NAA was proved efficient for the multiplication stage
Conclusion
- The bulb segment Lilium plant can be effectively used for the micropropagation.
- The Lilium is an important medicinal herb with various pharmacological actions.
- Present study shows that after two weeks of inoculation, maximum number of shoot were obtained in medium supplemented with MS Media +1.5 mg/l KN + 0.1 mg/l NAA
- The NAA along with BAP is proved effectively for multiplication, the best results were obtain on the 1.0 mg/l BAP+ 0.2 mg/l NAA.
- From these study it was concluded that 0.5 mg/l BAP + 0.1 mg/l NAA for initiation and.5 mg/l KN + 0.1 mg/l NAA for multiplication was observed

Bubble formation from media leads contamination
May 2024
Banana Micropropagation
Plant tissue culture is a collection of experimental methods of growing large number of isolated cells or tissues under sterile and controlled conditions.
Banana is one of the world’s most important fruit crop. It is grown in all type of tropical agriculture systems. The yield depends not only on the quality of soil and fertilization, but largely upon the control of the diseases.
An important objective of micro propagation of banana is to produce large number of disease free planting material and to satisfy the large need of banana planting materials
Stages of micro propagation of banana
1. Selection of mother plant
2. Preparation of explants
3. Fresh inoculation
4. Multiplication
5. Rooting
6. Planting out
7. Primary hardening
8. Secondary hardening
9. Field planting
Selection of Mother plant – we take sucker as an explnat , I take suckers in feild of vigyan ashram with help of Bhanudas sir
- Trails on Banana for 15 culture bottles – Grow well upto 14 days , after that culture bottles get contaminate
- Trail on Napier for 10 culture bottles
- Subculturing of Lilium
Culture bottles get contaminitated after 6 days , further I discussed with Shanbagh Sir about that and communicate with Lokhande Sir about contamination.
