摘要:
以桑树(Morus alba L.)为研究材料,在相同Na+浓度下,研究了中性盐(NaCl)和碱性盐(Na2CO3)胁迫下桑树幼苗生长和光合特性的响应特性。结果表明,100 mmol/L NaCl对桑树幼苗的生长和光合影响较小,桑树幼苗可以通过增加根冠比和叶片非光化学淬灭(NPQ)来适应盐胁迫。但是,50 mmol/L Na+浓度下,Na2CO3胁迫对桑树幼苗植株的生长和根系生长的抑制效果明显大于NaCl的。同时,Na2CO3胁迫降低了桑树幼苗叶片的叶绿素含量和桑树幼苗叶片对光能的利用能力,光饱和时的最大光合速率(Pmax)降低,并且桑树幼苗叶片吸收的光能不能完全用于电子传递,而NPQ等光合热耗散能力受抑制,导致过剩光能的大量积累。因此,在相同Na+浓度下,碱性盐(Na2CO3)胁迫对桑树幼苗的伤害比中性盐(NaCl)胁迫的严重,Na2CO3胁迫不但抑制了桑树幼苗根系的生长,而且降低了叶片的光合热耗散能力。
Abstract:
The experiment was conducted to investigate responses of growth and photosynthetic characteristics of mulberry(Morus alba L.)seedlings to neutral salt(NaCl)and alkaline salt(Na2CO3)with equivalent concentration of Na+. The results showed that effects of 100 mmol/L NaCl stress on plant growth and photosynthetic characteristics of mulberry seedling were not serious, and mulberry could adapt to NaCl stress by increasing root and shoot ratio and non-photochemical quenching(NPQ). However, whole plant and root growth of mulberry seedlings inhibited by 50 mmol/L Na2CO3 were more seriously than under NaCl stresses with equivalent concentration of Na+.Total chlorophyll and chlorophyll a contents, light utilization capability and photosynthetic rate at light saturation(Pmax)in leaves of mulberry decreased under Na2CO3 stress. But photosynthetic heat dissipation such as NPQ as inhibited which resulted in a large accumulation of excess light energy. It concluded that mulberry seedlings were injured by alkaline salt(Na2CO3)more seriously than that of by neutral salt(NaCl), Na2CO3 stress not only inhibited root growth of mulberry seedlings, but also blocked photosynthetic heat dissipation.
