| 摘要: |
| 试验采用膜下滴灌方式，研究了四个水分处理，即W0极度胁迫（灌水量450 m3·hm-2）、W1重度胁迫（灌水量1 530 m3·hm-2）、W2轻度胁迫（灌水量1 890 m3·hm-2）、W3充分灌溉（灌水量2 250 m3·hm-2）对瓜尔豆生长与逆境生理指标的影响。结果表明，W2处理对瓜尔豆产量性状和各生理生化指标的影响较为明显。各水分处理对产量的影响为：W2＞W1＞W3＞W0；W2处理前期可以显著增加瓜尔豆的株高和茎粗，鼓粒期后以W3处理为最优。生理指标中，处理W2、W3均可提高瓜尔豆叶片可溶性糖、可溶性蛋白及脯氨酸等渗透调节物质并降低丙二醛含量；鉴于W2处理叶绿素、可溶性蛋白、产量和POD酶活性等各项指标都表现出优于或近似于W3处理的效果。轻度胁迫既可实现高产，又能最大限度地节约水分，是非充分灌溉的良好选择。 |

| Abstract: |
| In order to extend water-saving irrigation for guar cultivation in Xinjiang, four water deficient treatments, W0 (extreme water deficiency, total irrigation amount was 450 m3·hm-2), W1（heavy water deficiency, total irrigation amount was 1 530 m3·hm-2), W2 (light water deficiency, total irrigation amount was 1 890 m3·hm-2), and W3 (full irrigation, 2 250 m3·hm-2)were conducted, in combination with plastic mulching and drip irrigation. Some growth parameters and physiological traits such as kernel weight, yield, and soluble sugar were analyzed. The results indicated
significant effect of W2. Before the pod setting stage, high values of height and stem diameters were observed with W2. Contents of soluble sugar, soluble protein and proline increased for W2 and W3, while malonaldehyde content decreased. Regarding physiological traits such as chlorophyll, soluble protein, and POD activity, W2 is recommended as the suitable practice for guar production in Xinjiang
