In 52 crosses, the ratio of distinct ovary enlargement to seed capsule development was 86.5%, but only 32.7% of crosses, whose seed capsules developed after 4 months. Hybrid plants of 19.2% crosses were obtained by embryo culture.
在52个杂交组合中, 86.5%的杂交组合具明显的子房膨大和果荚发育,但授粉4个月后未变黄落果的杂交果仅占组合数32.7%,经胚胎培养获得植株的杂交组合只占组合数的19.2%。
