Culture medium for culturing peanut gynophores

Abstract

The invention discloses a culture medium for culturing peanut gynophores, which is prepared from a seedling raising substrate used as a main raw material, and white lime and a gelatinizer used as auxiliary materials. The culture medium is prepared by evenly mixing the white lime, gelatinizer and seedling raising substrate in a mass ratio of 1:(5-380):(25-1520). The culture medium mainly solves the problem that the overground gynophores of peanuts can not penetrate into soil to develop into full pods, enhances the propagation coefficients of peanut hybrid F1 and rare seed resources, and can solve the problem that the interspecific cross subsequent generation can not form pods since the plant grows vigorously and the gynophores are too far away from the ground.

Description

technical field [0001] The invention relates to the technical field of peanut cultivation, in particular to a culture medium for peanut needle cultivation. Background technique [0002] Peanut is a self-pollinating plant that blooms above ground and bears fruit underground. The ovary stalk can be formed 3 to 6 days after the embryo of peanut is fertilized. The ovary stalk and the ovary at its tip are collectively called fruit needles. The characteristics of ground growth, the fruit needles are buried in the soil for 4 to 6 days, and the ovary expands horizontally in the soil and develops into pods. Under natural conditions, the pods of the same plant have great differences in maturity due to their different insertion positions. Usually, the fruit needles with higher insertion positions cannot be buried in the soil in time because of their distance from the ground, and cannot grow to maturity. Ripe pods lead to ineffective use of some fruit needles. In peanut interspecific ...

Problems solved by technology

Under natural conditions, the pods of the same plant have great differences in maturity due to their different insertion positions. Usually, the fruit needles with higher insertion positions cannot be buried in the soil in time because of their distance from the ground, and cannot grow to maturity. Ripe pods, resulting in the ineffective use of some fruit needles

In peanut interspecific hybrid breeding, interspecific hybrids have low fertility, and the formed fruit needles are easy to abort. The rescue of retired embryos requires high conditions and a large workload, and the success rate is low. On the other hand, the offspring of interspecific hybrids grow Lush, the formed fruit needles cannot enter the soil, and the plant has few pods
