| 摘 要： | 以新疆特有野生果树天山樱桃和野生樱桃李叶片为试材,采用自然干旱的方法,测定了不同水分胁迫下天山樱桃和野生樱桃李叶片相对含水量、电解质渗出率、脯氨酸含量和可溶性糖含量的变化,并进行了比较。结果表明:随着水分胁迫程度的加剧,天山樱桃和野生樱桃李叶片相对含水量缓慢降低,电解质渗出率升高,脯氨酸含量不断积累,可溶性糖含量先上升后下降。

| Abstract: | A comparative study of different water-stress of Cerasus tianschanica and Prunus divaricata were carried out,according to the four main physiological indexes including the relative tissue water content,electrolyte permeate rates,proline content and soluble sugar content of leaves under natural drought method.The results showed that two kinds of wild fruit tree under different degree of water stress,along with the time of water stress,the relative tissue water content decreased;electrolyte permeate rates increased;proline content continued to increase,the soluble sugar content showed increasing first and then decreasing. |
