Abstract

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.

Key words: pumpkin rootstock, seed coating, fungicidal effect
