Problems solved by technology

[0003] Oil palm breeding is mainly carried out through seeds, but because oil palm genes are generally heterozygous, it is difficult to preserve the genetic traits of the parents in their offspring, and the population uniformity is poor. Moreover, oil palm has only one growth point, which makes it difficult to realize traditional clonal breeding

Abstract

The invention discloses a rooting induction, root promoting and seedling cultivation method of oil palm plantlets. The method comprises the following steps: carrying out conventional treatment on rootless plantlets of oil palm under a sterile condition, and then transferring to a rooting induction culture medium to cultivate; inducing a plant to form a root, and then transferring to a root promoting and seedling cultivation culture medium to carry out root promoting and seedling cultivation, so as to obtain a complete plant of the oil palm plantlets with a developed robust root. A set of rooting induction, root promoting and seedling cultivation technology of the oil palm plantlets, which is strong in maneuverability, and short in rooting and seedling cycle, and saves the cost is built by using different culture media and cultivation conditions, so as to obtain the developed robust root. The rooting induction, root promoting and seedling cultivation method can be applied to large-scale efficient production of the oil palm plantlets, a technical support is provided for production of high-quality oil palm plantlets, and development of high-efficiency commercialized production of the oil palm plantlets is facilitated. Therefore, the rooting induction, root promoting and seedling cultivation method has practical significance.

Description

Technical field [0001] The invention belongs to the technical field of plant tissue culture, and relates to a rooting induction and root-promoting strong seedling culture method, in particular a rooting induction and root-promoting strong seedling culture method of oil palm tissue culture seedlings. Background technique [0002] Oil palm (Elaeis guineensis Jacq), Palmae (Palmae) oil palm is a perennial single-growing tree, one of the important oil crops in the tropics, and is known as the "World Oil King". Oil palm has a very high oil production. It can be used as edible oil, industrial raw material, bio-energy, etc. It has a wide range of uses. The market demand is large and popular. The industry is developing rapidly. Therefore, tropical and subtropical regions around the world are competing to introduce oil palm for cultivation. [0003] Oil palm breeding is mainly carried out by seeds, but because oil palm genes are generally heterozygous, the genetic traits of its offspring ar...
