An Efficient System for Plant Regeneration from Immature Embryo of Chinese Jujube
摘要
Abstract
An efficient system for plant regeneration from immature embryo of Chinese jujube was established by u-sing two callivars of male sterile No. 3CJMS3) and 'Jinmangguozao'. The results showed that the plant regeneration could be achieved by two types of procedures: direct embryo germination and generation of callus of cotyledon. Cold treatment could efficiently accelerate the direct plant regeneration from immature embryo. The plant regeneration rate of immature embryos, which were kept at 0~4℃ for 60 days and then inoculated in medium MS + sugar 30 g ? L-1 + agar 3. 3 g ? L-1, was as high as 93. 3%. Callus could be induced from 98. 9% of cotyledons damaged during smashing stones in medium MS +maltose 20 g ? L-1 +agar 3. 3 g ? L-1 +TDZ 1. 0 mg ? L-1 +NAA 0. 2 mg ? L-1 within 40 days. Adventitious buds occurred in 74.1% of the callus cultured in medium MS + maltose 20 g ? L-1 +agar 3. 3 g ? L-1 +TDZ 1. 0 mg ? L-1 for 40 days with cluster buds rate of 70. 4%. 1/2MS + sugar 20 g ?. L-1 + agar 3. 3 g ? L-1 + IBA 1. 0 mg ? L-1 + IAA 0. 01 mg ? L-1 was proper rooting medium and the rooting rate reached 80. 8% in 40 days.关键词
