| Abstract: | The blossom biological characteristic was observed by taking Philadelphus schrenkii which growed in Jiangnan forestry centre working circle of Panshi city.The result showed that florescence of groups, average individual florescence and average full-blossom period was 31, 27, 14 days under the climate condition of 2016.There were 4~19 florets inserted on simple inflorescence and the 8~10 was in majority.The opening time of simple inflorescence was 12~14 days.The opening time simple flower was 8~9 days.The flower whose color was white and pure emitted delicate scent.The effective accumulative temperature of more than 10 ℃ was 631 ℃ before florescence.The duration of flowering was 586 ℃.There were 24 days rainy during flowering. |
