马铃薯实生种子小,能量低,发芽期间能量转化慢;种子需经8～12小时达吸胀饱和,其饱和吸水量占绝对干物重的86％～105％;种子发芽在13～17℃变温和25℃恒温发芽最好,对光暗反应不敏感;贮藏2～3年的种子发芽力最高,室温下贮藏7年丧失种用价值;种子经卅烷醇浸种(50ppm浸4小时)、CO_2激光辐射10秒钟、50～60℃温汤浸种均能显著提高发芽力。α-萘乙酸浸种(10ppm15分钟)对发芽没有显著影响,但可促进幼苗根系发育。
Potato seedlings with low energy, low energy, slow energy conversion during germination; seeds need to be saturated after 8-12 hours of absorption, the saturated water absorption accounted for 86% to 105% of the absolute dry weight; seed germination at 13 ~ 17 ℃ warm The germination was the best at 25 ℃ and insensitive to the light and dark reaction. The seed germination was the highest in 2 ~ 3 years after storage, and the seed germination value was lost after 7 years of storage at room temperature. The seed was soaked in 卅 alkanol (50ppm for 4 hours) Radiation for 10 seconds, 50 ~ 60 ℃ Wen Tang soaking can significantly improve the germination. Soaking α-naphthalene acetic acid (10ppm for 15 minutes) had no significant effect on germination, but it could promote seedling root development.
