摘要/Abstract

摘要： 用随机区组试验和方差分析方法, 研究了培养温度、贮藏温度、GA 处理和光照强度对乌蕨( Sphenomeris chinensis) 孢子萌发的影响。与室温(20～25℃ ) 相比, 培养温度在28℃时, 孢子最大萌发率相近而萌发速率明显较高。贮藏温度(A) 极显著( P < 0 . 01 ) 影响孢子萌发率, - 20℃ 贮藏降低萌发率; GA (B) 对孢子萌发率无显著影响。光照强度(C) 极显著( P < 0.01) 影响孢子萌发率, 充足光照和弱光照无显著差异, 黑暗处理降低萌发率。A×B, A×C, B×C 及A×B×C 交互效应不显著。

Abstract: Effects of culture temperature , storage temperature , GA treatment and illumination intensity on spore germination of Sphenomeris chinensis were studied using randomized blocks experiments and analysis of variance . Compared with room temperature (20 - 25℃) , the germination velocity was higher at the culture temperature of 28℃, although their maximal germination percentage was the same . Storage temperature (A) significantly ( P < 0 .01) affected spore germination , and germination of spores was reduced when stored at - 20℃. GA (B) did not affect germination. Illumination intensity (C) significantly ( P < 0 . 01) affected germination. There were no significant difference between full and weak illumination , but the dark reduced germination percentage . A×B, A×C, B×C and A×B×C had no significant interaction effect .
