低海拔地区浙江红花油茶无性系的开花物候特性

为研究低海拔区域浙江红花油茶无性系开花物候特性,对浙江金华东方红林场的22个浙江红花油茶无性系开花物候、花期长短、开花数量进行了调查观测.结果表明：低海拔地区浙江红花油茶无性系花期始于1月下旬,结束于4月中下旬,花期长达62.5 d,花期较集中,但开花期容易受到气候的影响.不同浙江红花油茶无性系开花物候差异显著,开花期最早的是无性系dy144,最晚的是无性系hy31.花期持续时间最长的是无性系hy54、hy179,花期持续时间均值为53.5 d;最短的是无性系hy58,花期持续时间均值为26.5d.22个无性系之间开花数量存在极显著差异（P＜0.01）.根据本试验的研究结果,其中无性系dy15...

Summary:为研究低海拔区域浙江红花油茶无性系开花物候特性,对浙江金华东方红林场的22个浙江红花油茶无性系开花物候、花期长短、开花数量进行了调查观测.结果表明：低海拔地区浙江红花油茶无性系花期始于1月下旬,结束于4月中下旬,花期长达62.5 d,花期较集中,但开花期容易受到气候的影响.不同浙江红花油茶无性系开花物候差异显著,开花期最早的是无性系dy144,最晚的是无性系hy31.花期持续时间最长的是无性系hy54、hy179,花期持续时间均值为53.5 d;最短的是无性系hy58,花期持续时间均值为26.5d.22个无性系之间开花数量存在极显著差异（P＜0.01）.根据本试验的研究结果,其中无性系dy156、hy8、hy28、hy31、hy43、hy47、hy59、hy63、hy54、hy71、hy179可以考虑作为园林观赏推广品种.

To study the flowering phenology of the Camellia chekiangoleosa clone in the low altitude area, 22 C. chekiangoleosa clones which came from Dongfanghong Forest Farm in Jinhua, Zhejiang Province, were investigated and analyzed, including the flowering phenology, the period of flowering phase, and the flowering quantity. The re- suits showed that the flowering period of C. chekiangoleosa clone in the low altitude area began in late January, and ended in late April. This period lasted for 62.5 days. The flowering period was relatively concentrated, but vulnera- ble to climate. The flowering phenology of the C. chekiangoleosa clone was significant different. The mean duration of long flowering period clone was 53.5 days ; while that of the short flowering period clones was 26.5 days. There were significant differences in the flowering quantity among the 22 clones （P 〈0.01 ）. According to the test results of the study, the clones suitable to be used as ornamental varieties were recommended.
