| 摘 要： | 通过人工模拟干旱胁迫处理和比较其它花生类型的耐旱品种，研究几个龙生型花生在缺水条件下的形态特征及恢复生长能力，试验表明，干旱胁迫显著抑制花生地上部营养体生长，但促进主根伸长和根系干物质积累，龙生型花生耐旱性状突出，但不同材料差异较大，马山二洋和托克逊小花生是耐旱性良好的龙生型种质。

| Abstract: | Morphological characters of drought tolerance in dragon groundnut genotypes were investigated by artificial drought stress treatment and compared with those of other botanic types of A.hypogaea L.. Water deficit was found to restrain the growth of shoots but stimulate tap root growth and increase root weight. The results indicated that dragon groundnuts tolerant to drought were largely due to both their shoots and roots. There was diversity of drought tolerance among different dragon groundnut genotypes with different key components of drought tolerance. Mashan Eryang and Tuokexun Xiaohuasheng were identified as the most tolerant genotypes among the materials involved through comprehensive assessment. |
