不同贮藏温度对桔梗花粉生活力及授粉结实能力的影响
Effect of Storage Temperature on Pollen Viability and Seeds Setting of Platycodon grandiflorum
摘要
Abstract
Pollens of Platycodon grandiflorum were cultured in the culture medium of ME3+BK+10% sucrose+150 g/L PEG (pH5.8). The results showed that the pollen germination were best at 30℃ for 1.5 h. Pollens of Platycodon grandiflorum were stored under different temperatures. The result showed that life of pollen at being stored under low temperature was prolonged significantly. The life span on pollen stored at 10 ℃, 4℃ and -20℃ in icebox was 60 d, 90 d and 150 d, respectively, while that for ambient temperature was about 4 d. Seeds setting of pollen after stored under different temperature was decreased with the storagetime extended, and seeds setting of pollen under ambient temperature storage was lower than those under low storage temperature.关键词
