中文摘要	黑果枸杞(Lycium ruthenicum)是民勤绿洲-荒漠过渡区主要的盐生植物,近年来由于对其营养价值和药用价值的认识,新疆、青海和甘肃等地拟在荒漠-绿洲过渡带开展黑果枸杞种植以改善盐碱土和增加当地农民经济收入。主要通过插枝和种子繁殖黑果枸杞,而盐胁迫对黑果枸杞种子在实验室和大田的萌发以及对黑果枸杞幼苗生长的影响还未知。于2014年在民勤开展了不同盐度溶液对黑果枸杞萌发和幼苗生长的影响研究。结果表明:淡水条件下,黑果枸杞种子的萌发及幼苗生长优于盐水条件;在室内培养试验中,黑果枸杞种子累积萌发数和萌发率随浇灌水盐度的增加而减少;室外大田试验淡水处理下黑果枸杞种子累积萌发数和萌发率高于其他盐度处理;黑果枸杞种子萌发和幼苗生长对盐胁迫较敏感,其形态和生理均显示出抑制特征,不同处理的幼苗根芽比随着培养液盐度的增加而增加。大田种植时,降低表层土壤盐度是黑果枸杞成功建殖的关键。
英文摘要	Lycium ruthenicumis one of the important halophytes in the Minqin oasis-desert transitional zone and has been planned to plant more in order to improve saline-alkalized soil and to increase the income of local farmers in the oasis-desert transitional zones in Xinjiang,Qinghai,and Gansu under the recognition of its nutritional and medicinal values in recent years.L.ruthenicum breeds mainly by cutting and seed propagation. However,the effects of salt stress on its seedling growth and seed germination in the laboratory and field are still unknown,and we carried out the research in seed germination and seeding growth of L.ruthenicum with different concentrations of salt solutions in 2014.The results showed that L.ruthenicumseed germination and seedling growth were better in the fresh water than in the salt water;the L.ruthenicumseed germination rates and cumulative number of germination in laboratory incubation study decreased with the increase of salinity; the L.ruthenicumseed germination rates and cumulative number of germination of field trials,are more in the freshwater solution than that in other salinity solutions;L.ruthenicum seeds germination and seedling growth were sensitive to salt stress,showing morphological and physiological inhibition characteristics,and the radicle/plumule ratio of different treatments with increasing salinity culture fluid increases.To reduce the salinity of surface soil when the seed germinated in the field,was a key to L.ruthenicum growth successfully.
