摘  要：
以罗布麻(Apocynum venetum Linn.)和大叶白麻(Poacynum hendersonii(Hook.f.)Woodson)种子为试材,研究了0(CK)、50、100、200、400、600mmol/L NaCl 6个盐浓度胁迫下种子发芽率及胚根、胚芽生长。同时,为揭示罗布麻幼苗耐盐特性,采用砂培法培养植株,分析了不同盐浓度胁迫下罗布麻幼苗不同部位生物量的变化。结果表明:盐胁迫可抑制2种罗布麻种子发芽率及胚根、胚芽生长,2种罗布麻种子萌发的耐盐临界值为400mmol/L左右,胚根生长的耐盐临界值为100mmol/L NaCl;600mmol/L NaCl可完全抑制罗布麻和大叶白麻种子的萌发,但解除盐胁迫复水后,2种罗布麻种子发芽率及胚根、胚芽生长恢复至对照水平;盐胁迫对种子发芽率、胚根、胚芽生长及幼苗不同器官生物量的影响表明,大叶白麻种子萌发和幼苗生长阶段较罗布麻耐胁迫,通过对2种罗布麻生境分析,认为这是与它们的生境相适应的。罗布麻种子萌发和幼苗生长耐盐性研究对盐碱地上罗布麻的人工栽培有重要指导意义。

摘  要：
Taking the seed of Apocynum venetumLinn.and Poacynum hendersonii(Hook.f.)Woodson as test material,the effect of different salt levels(0,50,100,200,400 and 600mmol/L NaCl)on seed germination rate,embryo growth and radicle growth of Apocynum venetum Linn.and Poacynum hendersonii(Hook.f.)Woodson were investigated.The changes of the biomass of apocynum different parts under different salt concentration were studied by sand culture method,in order to reveal salt tolerance features of apocynum.The results showed that salt stress inhibited the seed germination rate and radicle growth of two kinds of appocynum,limit value of salt stress to seed germination rate and radicle growth was respectively 400mmol/L NaCl and 100mmol/L NaCl;600mmol/L NaCl completely inhibited seed germination,but after the salt stress was relieved,the seed germination rate and radicle growth were not remarkably different from that in distilled water;salt tolerance of Poacynum hendersonii(Hook.f.)Woodson during seed germination rate and radicle growth was more higher than that of Apocynum venetum Linn,which may be adaptative to their inhabited environment.The study about seed germination and salt tolerance of apocynum was guiding significance for apocynum artificial cultivation.
