Abstract:毫秒延迟发光测定结果表明低温弱光处理黄瓜叶片导致类囊体原位(in situ)耦联度显著降低。DCCD可以恢复低温弱光处理的黄瓜叶片的毫秒延迟发光的慢相强度和反映类囊体膜质子吸收的9-AA(9-Aminoacridine)荧光猝灭能力,说明类囊体耦联度降低的原因是质子由CF0大量快速渗漏。进一步研究结果表明,活性氧和CF1的脱落不是低温弱光引起黄瓜类囊体耦联度降低的根本原因。

Abstract:长江源区位于青海省西南部 ,北纬 31°35′~ 36°30′,东经 89°35′~ 97°55′。本地区共有种子植物 62科、32 1属、1 377种。区系特征表现为 :1 .温带成分占 96.81 % ,以绝对优势确定了本区系明显的温带性质。2 .世界成分多为衍生 ,更兼所含的中国特有属亦多为衍生 ,表明本区系的年轻性和衍生的性质。 3.主要植被均属典型的高寒类型 ,它们的建群种亦多为典型的高寒植被的特征种。所以 ,本区系高寒植被典型 ,特征种典型 ,高寒区系特色明显。4.生态环境对本区系特征的塑造表现为高寒生态因子的选择和高山特化的作用强烈 ,而在一定程度上湿冷生性质和寒旱生性质的高山特化作用更为明显。长江源区的植物区系是唐古特地区高山区系的代表之一。在中国特有种的分析中 ,本区系与横断山和甘肃南部区系的联系最为密切 ,三者间的共有种最为丰富 ,有 593种 ,占本区中国特有种的 74.69%。关于唐古特地区的南部界线 ,作者认为 ,李锡文等 (1 993)的“川西北、甘西南、青东南小区”同唐古特地区关系最为密切 ,若能在考虑这一因素的前提下来划分似乎更合适 ,也更能体现唐古特地区作为一个独立区系的自然界线。
