摘 要:
将巴西陆稻IAPAR9种子置于不同水分处理的土壤中进行萌发试验.结果表明：随着土壤含水率的降低,IAPAR9的发芽速率、发芽势、发芽率、发芽指数、活力指数和苗体素质均出现不同程度的降低.相对含水率为80%处理的各项指标均优于其他处理,说明IAPAR9种子萌发的最佳土壤含水率在土壤田间持水率的80%左右.[著者文摘]

Abstract:
According to the test, in which the seed of IAPAR9, a kind of upland rice from Brazil, are put in different soft for sprouting seed. It is shown that with the reducing of the soil moisture content, there are also various reductions in IAPARg＇s sprout speed, germinative tenden- cy, germinative percentage, sprout index, index of vigor and quality of shoot. Under the situation that the water rate is 80%, every index is superior to other treatments. It is suggested that IAPAR9 seed sprout is best when the water rate is about 80% in soil.[著者文摘]
