摘要
[目的]研究干热处理对不同成熟度葫芦砧木种子的影响。[方法]以不同成熟度的葫芦砧木种子为试验材料,经过干热处理后研究种子的发芽势、发芽率和正常出苗率。[结果]自授粉日至采收达到55 d以上的4个处理葫芦种子经过干热处理后种子的发芽势、发芽率和正常出苗率均分别达到97%、97%和90%。自授粉日至采收为45 d和50 d的葫芦种子经过干热处理后的发芽势和正常出苗率显著低于55 d以上的种子。[结论]选择成熟度较高的葫芦砧木种子进行干热处理对种子活力影响较小。
[ Objective ] The aim was to explore the effects of dry heat treatment on different maturity grades of Lagenaria rootstock seeds. [ Method] Seed germination force, germination rate and emergence rate of Lagertaria rootstock seeds were evaluated to explore the effects of dry heat treatment on different maturity grades of seeds. [ Result ] The result indicated that four treatments of the seeds during over 55-day-perlod from pollination to harvest could respectively reach 97% germination force, 97% germination rate and 90% emergence rate after dry heat treatment. The germination force and emergence rate of Lagenaria seeds during 45- and 50-day-period from pollination to harvest decreased significantly after dry heat treatment. [ Conclusion ] Lagenaria rootstock seeds of the higher maturity grades for dry heat treatment have less damage to their viabilities.
