Effects of mixed-culture densities of Spartina alterniflora on eco-physiological characteristics of Kandelia candel seedling [PDF]
, 2007 按照不同密度将互花米草与秋茄进行混种,对比研究胁迫条件下秋茄幼苗生长、光合特性及其渗透调节物质变化规律。结果表明,低密度互花米草促进秋茄的茎长以及各部分生物量,高密度则起抑制作用。随着互花米草密度的增大,秋茄幼苗叶片光合速率、气孔导度、蒸腾速率、水分利用率和蛋白含量均下降;相反,胞间CO2浓度、可溶性糖、淀粉、脯氨酸含量却上升,这些变化有利于对抗互花米草带来的不利影响。 【英文摘要】 Kandelia candel seedlings were mix-cultured with Spartina ...
