剪口处理和土壤水分对巴天酸模种子萌发的影响
|
摘要
以巴天酸模(Rumex patientia Linn.)种子为试材,以其剪口种子为处理,未剪口种子为对照,在土壤含水量60%和沙土含水量46%条件下进行种子萌发试验;并对种子进行冷冻处理,分析了土壤水分、剪口处理和冷冻时间对巴天酸模种子的萌发率和萌发势的影响。结果表明:沙土含水量为46%时,剪口处理对其萌发率和萌发势都有显著影响;土壤含水量为60%时,剪口处理加大了其萌发势。无论剪口处理还是未剪口,土壤含水量为60%的萌发率高于沙土含水量为46%的萌发率。剪口处理后,随着冷冻时间的延长,种子萌发率有所提高。说明土壤水分条件、剪口处理和冷冻时间延长是巴天酸模种子萌发的重要因素。
Seed of Rumex patientia Linn.was used as test material and the seeds with snipped(non-snipped as CK)and frozen were treated to the germination experiment under the condition of soil moisture content 60%and the sand moisture content 46%.The effect of soil moisture,snipped and frozen time on the germination rate and germination energy of Rumex patientia Linn.was analyzed.The results showed that there were greatly significant influences under the sand moisture content of 46%on snipped.But when the soil moisture content was 60%,the germination energy was increased on snipped.However,the germination rate in the moisture content of 60%much higher than the sand moisture content of 46% whether the snipped or non-snipped.The germination rate was improved as the frozen time become longer under snipped.This study illustrated that the main factors of Rumex patientia Linn.seed germination were soil moisture,snipped and the frozen time.
