| 摘 要： | 为提高杂交后代种子的发芽率,以不同成熟度的3个品种为试材,研究了影响桃种子发芽的因素。结果表明,随着果实生育期的延长,桃种子的干鲜重比值均不断增加。日本86成熟早、果实生育期短,种子处理后未能发芽;而中熟品种巴9及晚熟品种凤凰水蜜,随着果实成熟度提高,低温处理时间的延长种子发芽率不断增加,最高发芽率和正常苗率均可达100%。说明不同品种、果实生育期、干鲜重比值、含水量、低温处理时间一定程度上均影响桃种子的萌发和小苗的生长。

| Abstract: | In order to improve the seed germination rate of peach hybrid,three peach cultivars with different maturation were applied to study the factors that affected the seed germination.The results showed that the ratio of dry weight to fresh weight of peach seed was constantly increased with the extending of fruit growth period.Japan 86,an early-ripening and short growth period variety,could not germinate in any treatments.For moderately-mature cultivar Ba 9 and lately-mature cultivar Fenghuangshuimi,when the fruit maturity rate increased and low temperature treatment time prolonged,their seed germination rates were increased continuously,and the highest germination rate and normal seedling rate could reach to 100%.All results indicated that different cultivars,fruit growth period,ratio of dry seed weight to fresh seed weight,water content in seed and low temperature treatment time all could affect the seed germination and plantlet growth. |
