木芙蓉种质资源在成都地区的适应性研究

Study on Adaptability of Hibiscus mutabilis Germplasm Resources in Chengdu Region

摘要: 对来自全国14个省份171份木芙蓉资源在成都地区的适应性进行了研究，结果表明：（1）大部分资源（80.70%，分布于北纬32°06'53"以南），在成都地区具有较好的适应性。（2）保存的资源中单瓣型资源（包括单瓣红色、单瓣白色及单瓣白变红）占比为57.25%，略高于重瓣型（42.75%）。（3）保存的木芙蓉资源有63.04%结实，其中单瓣型的木芙蓉占比62.07%，来自福建的资源占比40.23%。这些研究结果对于木芙蓉种质资源保存及推广应用将具有重要意义。

Abstract: The adaptability of 171 Hibiscus mutabilis resources from 14 provinces were studied in Chengdu. The results showed that: (1) Most of the resources (80.70%, distributed in the south of 32°06'53"N) had good adaptability in Chengdu area. (2) Among the preserved resources, the proportion of single petal type (including single-petal red, single-petal white and single-petal white to red) was 57.25%, which was slightly higher than that of double-petal resources (42.75%). (3) 63.04% of the preserved Hibiscus mutabilis resources were firm, of which 62.07% were single petal and 40.23% were from Fujian. These results will be of great significance for the conservation and popularization of Hibiscus mutabilis germplasm resources.
