三种荒漠植物幼苗对NaCl胁迫的叶绿素荧光响应
Responses of three desert plant seedlings to chlorophyll fluorescence
摘要
Abstract
Understanding salt tolerance of plants in the desert transitional zone of the very arid areas is conducive to reveal its salt tolerance mechanism, protect and make use of these plants.Chlorophyll fluorescence technique was adopted to study the effect of Nacl stress on seedling leaves' photosystem Ⅱ of three greenhouse plants,alhagi sparsifolia, apocynum venetum and halostachys caspica.NaCl stress induced the decrease of the maximum quantum yield (Fv/Fm) of PSⅡ in alhagi sparsifolia and apocynum venetum with various reasons;there is no change of Fm but increase of Fo in alhagi sparsifolia, increase of the beginning fluorescence (Fo) in apocynum venetum and decrease of its maximum Fm at the same time; no effect of NaCl was observed in halostachys caspica.Salt stress induced the decrease of adaptation to light in three plants among which more significant decrease was observed in alhagi sparsifolia and apocynum venetum.Halostachys caspica was the one of maximum salt tolerance, and apocynum venetum the minimum among the three plants.关键词
