What is the best propagation method for pineapple?
Pineapple is very easy to propagate vegetatively. Suckers arising in the axil of the leaves on the main stem form roots and can be used for propagation. Even the crown of leaves above the fruit and parts of the stem itself can be used.
What is in vitro plantlets?
Micropropagation or in vitro propagation is the clonal propagation of plants by tissue, cell and organ culture methods. It involves the aseptic culture of explants of tissues and organs in closed vessels using defined culture media in a controlled environment.
Are pineapple plants self fertile?
To produce seeds, pineapples must be cross-pollinated. All of the pineapples in one commercial field are genetically the same, so if pollen is transferred from one plant to another, it is still self-pollination.
What is commercial propagation method of pineapple?
Propagation – Commercially the pineapple plant is propagated by vegetative material, an asexual reproduction, without new combinations of genes. However, sexual reproduction is feasible as seeds are produced in the fruits if cross pollination between cultivars occurs, naturally or under controlled conditions.
How do you Micropropagate plants?
The process of micropropagation can be divided into four stages:
- Initiation stage. A piece of plant tissue (called an explant) is (a) cut from the plant, (b) disinfested (removal of surface contaminants), and (c) placed on a medium.
- Multiplication stage.
- Rooting or preplant stage.
- Acclimatization.
How long do pineapples take to grow?
Commercial pineapple plant fruiting is grown on a two to three year fruit crop cycle that takes 32 to 46 months to completion and harvest. Pineapple plants do indeed die after this cycle, but they produce suckers, or ratoons, around the main plant while it is flowering and fruiting.
How long does it take for a pineapple to grow?
Tops take about 24 months to fruit (even longer in colder climates). Suckers take about 18 months and slips can fruit within a year. Generally a pineapple will flower as soon as it is big enough, so the happier it is and the better you look after it the sooner it will flower.
How do pineapples reproduce naturally?
Slips. The pineapple produces several plantlets near the base of the fruit called slips. These slips appear as red or green outgrowths along the stalk. Pinch them away from the main plant and plant them in the ground at a depth of between 3 and 6 inches.
What is the best sterilization method for MD2 pineapple plants?
The optimal duration of sterilization with 2% sodium hypochlorite as well as the The optimal duration of sterilization with 2% sodium hypochlorite as well as the optimal concentrations of Benzylaminopurine (BAP) and sucrose for the in vitro culture of MD2 pineapple plants were investigated on MS medium.
Is there an IN VITRO technology for large scale multiplication of pineapples?
Employment of in vitro technology for large scale multiplication of pineapples ( Ananas comosus ). Pak. J. Bot., 36: 611-615. 13: Kiss, E., J. Kiss, G. Gyulai and L.E. Heszky, 1995. A novel method for rapid micropropagation of pineapple. HortScience, 30: 127-129. 14: Kyte, L. and J.G. Kleyn, 1996.
Can BAP and sucrose increase the growth and multiplication of pineapple?
Effect of different concentrations of BAP and sucrose on the growth and multiplication of pineapple in vitro: A second medium for the multiplication of the regenerated buds was supplemented with different concentrations of BAP (2, 4, 6 and 8 mg L -1) with 30 g L -1 of laboratory grade sucrose as the carbon source and solidified with 6 g L -1 agar.
Is there an in vitro culture of pineapple?
