Effects of the climate during flowering period on post-flowering fruit setting in Camellia oleifera
-
摘要: 花期气候条件是影响油茶Camellia oleifera开花授粉和翌年产量的主导因子之一。1978 － 1984年，在浙江省临安市、龙游县的研究表明，日平均气温5 ℃以上的无霜晴天，人工授粉可以坐果，8 ℃以上授粉媒介正常活动可以自然授粉，中早花类型在日平均气温8.8~16.0 ℃时坐果率最高。影响明显的气候因子是降雨和霜冻：降雨只影响雨日的开花授粉，对雨前授粉超过6 h和雨后开的花影响不大；霜冻危害重时间长，是油茶花的最大杀手。受气温和霜冻的综合影响，随着花期推迟，坐果率逐渐下降，12月（浙江北部11月下旬）以后开的花坐果率极低。观察发现，在天然油茶群体中有抗冻的植株存在。表6参9Abstract: The climatic conditions during the flowering period are one of leading factors influencing flowering，pollination and the fruit yield of the following year in Camellia oleifera. Researches were conducted in Linan and Longyou of Zhejiang Province in 1978 - 1984. The results showed that artificial pollination conducted when the daily average atmospheric temperature was 5.0 ℃ and above，sunny and no frost could result in fruit setting，and natural pollination occurred when it was 8.0 ℃ and above and pollinators moved about normally. Rainfall and frost were the main impact climatic factors. Rainfall only influenced flowering and pollination on raining days and had few effects on flowers that were pollinated 6 hours before rain or opened after rain. Frost had a heavy damage for a long time. Individual trees which can be resistant to frost were observed in a natural population.［Ch，6 tab. 9 ref.］
