【摘要】 检测水浮莲(Pistia stratiotes L.)在不同pH和不同温度条件下的生长能力以及对NaCl的敏感性,结果表明,水浮莲最适合的生长繁殖温度条件为20～35℃,低于10℃时不能够正常生长繁殖,低于5℃时难以保持生存能力;最适pH范围在pH6～10之间;水浮莲对NaCl非常敏感,10 mM.L-1NaCl影响水浮莲的正常生长,高于此浓度的NaCl会导致水浮莲的黄化以及死亡.更多还原

【Abstract】 The result of the examinaiation of living ability under the different pH,temperature and sensitivity to NaCl indicat that the optimum growth temperature for Pistia stratiotes is 20~35℃,Under the temperature lower than 10℃ Pistia stratiotes L·can not breed normally and under the temperature lower Under 5℃ Pistia stratiotes can hardly keep its life;the optimum pH range for Pistia stratiotes is pH6~10; Also Pistia stratiotes is very sensitive to NaCl,10 mM·L-1 NaCl affect its normal live, NaCl higher than this concentration can make Pistia stratiotes yellowing and finally make it death.更多还原
