Rapid seedling method of fruit tree hybrid seeds

Abstract

The invention discloses a seedling method and particularly relates to a rapid seedling method for fruit tree hybrid seeds. The rapid seedling method includes after the fruits are collected, removing pulps and taking out seeds without shells, placing the seeds in culture dishes, pouring sterile water with 20-25 degrees in the culture dishes, and soaking the seeds in the sterile water within 24-36hs; removing seed coats, sterilizing the seeds without coats with 0.08%-0.12% potassium permanganate solution for 24-36secs, and placing the seeds waking up from dormancy in the container filled with the sterile water for seeding; seeding the seeds waking up from the dormancy in watered matrixes for culture in a phytotron; after the seeds grow the fifth or the sixth leaves, removing the seeds out of the phytotron and culturing the same under the indoor temperature for 2-3 days for water controlling, and then transplanting the seeds to feeding blocks or fields to grow. By the application of the rapid seedling method, seed development period is shortened, and emergence rate of hybrid seeds is increased.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for rapidly growing seedlings of hybrid seeds of fruit trees, which is an efficient method for growing seedlings. Background technique [0002] At present, in the process of hybrid breeding of fruit trees, the hybrid seeds cannot be sown immediately due to different degrees of dormancy. Usually, the traditional technology of burying and sand storage is used to make them pass the dormancy, and they are sown in the spring of the lily year to germinate, resulting in hybridization. Seeds need to wait for 6-10 months from harvesting to sowing. For fruit trees with 3 to 7 years of childhood, these 6-10 months are equivalent to a growing season for deciduous fruit trees. If it can be shortened by 1 / 3 To 1 / 7 of the time, enter the fruiting state in advance, which is of great significance to speed up the process of breeding new varieties of fruit trees. Using the traditional san...

Problems solved by technology

However, because there are many kinds of fruit trees, and the hybrid seeds of the same type of fruit trees have great individual differences and differences in the ability to sense exogenous hormones, it is not easy to grasp the concentration, dosage, and treatment time of exogenous plant hormones, and the effect is not good, and break dormancy After the seeds are affected by too much or too little exogenous hormones, problems such as premature aging and deformity often occur during seed germination, resulting in low emergence rate, poor seedling rate, and poor seedling quality.
