Studies on photosynthesis and growth of Changium smyrnioides and Anthriscus sylvestris(明党参、峨参光合与生长的研究)

明党参和峨参具相似的光合特征:3月的光合速率、光饱和点及光补偿点均大于1月;光合强度接近;对冬季至早春的光利用能力较强,而对春夏的强光都不能充分利用.明党参的比叶面积(SLA)、叶面积比(LAR)、叶生物量比(LMR)均低于峨参,光合持续时间比峨参短160 d左右.两种植物的株高、冠幅、最大带柄叶长和叶片数均在早春的3、4月份迅速增大,进行旺盛营养生长,明党参的4个生长指标均低于峨参.明党参总光合量远低于峨参,物质积累及生长较峨参缓慢,生殖投入低,生活史长,种群受到干扰后不易迅速恢复....
