经过对蕨菜 (孢子体 )不同生育阶段的地上部植株叶片的叶绿素含量、呼吸酶活性及地上部生长量变化规律的研究表明 :( 1)不同生育阶段的叶绿素 a、叶绿素 b存在明显的差异 ;( 2 )不同生育阶段的过氧化氢酶活性、过氧化物酶活性呈下降的趋势 ,( 3 )不同生育阶段的地上部鲜重、干重、干重 /鲜重呈增长趋势 ,含水量呈下降的趋势
The changes of chlorophyll content, respiration enzyme activity and aboveground biomass of shoots of aboveground parts of bracken (sporophyte) at different growth stages showed that: (1) chlorophyll a and chlorophyll b were significantly different at different growth stages ; (2) catalase activity and peroxidase activity in different growth stages showed a decreasing trend; (3) fresh weight, dry weight and dry weight / fresh weight of above-ground parts showed an increasing trend at different growth stages, and the water content Showing a downward trend
