Abstract:

Effects of two kinds rape seed coating on hybrid rape seeds and normal rape seeds’ storage characteristics were studied by detecting rape seed vigor in storage. The results show that the coated rape seed had a little change in germinant energy, germinant percentage and adult seedling rate at the different stages of storage period, meanwhile these parameters of uncoated controls decreased rapidly as the storage time prolonged. After 4 months’ storage， the germinant energy, germinant percentage and adult seedling rate of coated hybrid rape seeds increased 78.2～140.1％、81.5～87.6％ and 91.5～123.5％ compared with uncoated controls respectively, and however these ones of coated normal rape seeds increased 5.2～8.9％、10.8～19.6％ and 6.3～28.4％ compared with uncoated controls respectively，which showed that seed coating could improve rape seeds’ storage significantly，and have more positive effects on hybrid rape seeds than on normal rape seeds，and the seed film agent exhibited better efficiency than seed pelleting agent on rape seeds.
