【摘要】 本文研究了普通刺梨（Rosa roxburgii,Tratt）的光合特性,结果说明:刺梨的光补偿点为1～1.5KLX。饱和点为38～40KLX,属C₃植物;光合速率在12～20mgCO₂·dm^-2·h^-1之间,叶栅栏细胞2～3层,细胞高宽比为4～7,呈园柱体,属阳性植物。同时对刺梨光合“午休”的主要成因进行了研究。更多还原

【Abstract】 The photosynthetic characters, chief weathes factors affecting photosynthesis, causes of photosynthetic"nooa sleep" on the field grown Cili were preliminarily studied. By means of nonlineer stepwise regression under"Greatwall-0520" computer,the fitted mathematical equations of weathes factors affecting photosynthesis were established.更多还原
