摘要:

本研究系统评价了12种不同类型种衣剂对南瓜砧木种子萌发和幼苗生长等方面的影响,以期筛选出对南瓜砧木种子萌发和幼苗生长具有综合促进效果的种衣剂。结果表明,不同种衣剂对南瓜砧木种子萌发和幼苗生长等方面的影响均存在较大差异。其中,瓜类种子专用悬浮种衣剂(FSC)表现最佳,处理后种子的出苗率达97.22%,百株鲜重达477.20 g,均(p<0.05)高于对照。同时,瓜类种子专用FSC的杀菌效果也最佳,培养4 d后种子表面的杀菌效果达100.00%。其次为4%咯菌·嘧菌酯微囊悬浮剂(CF),处理后种子的出苗率为91.67%,百株鲜重达476.23 g。此外,每1 g含1 000亿芽孢的枯草芽孢杆菌可湿性粉剂(WP)和40%克菌·戊唑醇悬浮剂(SC)能够显著促进种子胚根的伸长,其中40%克菌·戊唑醇SC处理后形成了“矮壮”株型,适合机械化嫁接作业。值得注意的是,70%噁霉灵WP处理会显著抑制种子萌发和幼苗生长,生产上应避免使用。综合安全性、种子萌发情况、幼苗生长情况和杀菌效果,瓜类种子专用FSC和4%咯菌·嘧菌酯CF具有最佳应用前景,可同步实现提高出苗率、壮苗培育和真菌防控的目的,为南瓜砧木种子的标准化处理提供技术支撑。

Abstract:

To screen for seed coating agents with comprehensive promoting effects on seed germination and seedling growth of pumpkin rootstocks, this study systematically evaluated 12 different types of seed treatments. The results showed that different seed coating agents had obvious differences in seed germination and seedling growth of pumpkin rootstocks. Among them, specialized cucurbit seed FSC performed the best. After treatment, the germination rate of the seeds reached 97.22%, and the fresh weight per 100 seedlings reached 477.20 g, which was significantly (p<0.05) higher than that of the control. At the same time, the fungicidal effect of specialized cucurbit seed FSC was also the best. After 4 days of cultivation, the fungicidal effect on the seed surface reached 100.00%. The second was 4% fludioxonil·azoxystrobin CF. After treatment, the germination rate of the seeds was 91.67%, and the fresh weight per 100 seedlings reached 476.23 g. Besides, Bacillus subtilis WP(100 billion spores per gram) and 40% carbendazim·tebuconazole SC significantly promoted radicle elongation, with the latter forming a “dwarf and sturdy” plant type, which was suitable for mechanized grafting. However, 70% hymexazol WP significantly inhibited seed germination and seedling growth and should be avoided in production. Considering safety, seed germination, seedling growth and fungicidal effect, the specialized cucurbit seed FSC and 4% fludioxonil·azoxystrobin CF showed the best application prospects, simultaneously achieving high emergence rate, robust seedling cultivation, and fungal disease control, providing technical support for standardized treatment of pumpkin rootstock seeds.
