| 摘 要： | 用ＧＡ、ＩＡＡ和Ｋｎ等植物激素为克服花生种间杂交（栽培种×Ａｒａｃｈｉｓｇｌａｂｒａｔａ）不亲和性，在不同发育时期以不同浓度进行处理。结果表明，ＧＡ处理平均出针率１４．２％－３３．３％，果针伸长８．７ｃｍ，子房膨大率７５．０％；ＩＡＡ处理子房膨大率８７．２％；Ｋｎ处理促进荚果形成，成荚率１２．５％－６５．１％。

| Abstract: | Hormones including GA, IAA and Kinetin were used to induce formation and growth of pegs and pods in some incompatible interspecific crosses between the cultivated groandnut and A. glabrata. The hormones with different concentrations were applied in different time after pollination. The GA increased the number of pegs by 14.2% to 35.3% with an average peg length of 8.7 cm,and 75% ovaries swelled in GA treatment. when IAA was also used after GA application, the ratio of swelling ovaries increased to 87.5%. Kinetin treatment improved the pod formation which ranged from 12.5% to 65.1% |
