There are three methods for pineapple seedling: plastic hormone germination, asexual propagation and tissue culture. The following methods are introduced in detail for your reference:
Time and method of accelerating pineapple germination: Choose plants with 40 cm green leaves from May to165438+1October, generally 40 cayenne and 35 phenanthrene. Each plant was perfused with a mixed solution of 250 mg/L ethylene glycol, 25 ml 1% urea and 0.5% potassium chloride to accelerate germination, and then treated with 25 ml 1200- 1500 times and 600-750 times on the 5th and 2nd days respectively.
Asexual propagation method of pineapple: common seedling raising method, that is, small terminal bud, small supporting bud, small sucking bud and fruit tumor bud are classified in the field, and then cultivated in the nursery. The small buds left on the fruit stalk after fruit picking are used for growth and seedling raising, and the old stems are used for cutting propagation.
