温室葡萄开花生物学特性观察

Observation on the Biological Characteristics of Grape Blooming in Greenhouse

对温室葡萄的开花物候期、开花顺序、开花日动态、环境因子对开花的影响、落花落果动态等几个方面进行观察，结果表明，温室葡萄开花习性与露地葡萄有明显的差异：温室葡萄开花日动态表现为明显的单峰曲线;开花受温度和湿度综合作用的影响;不同品种最适的开花环境条件有所差异。

The florescence, sequence, daily development, affections of environment factors, premature drop were observed.
