大棚葡萄果实发育规律研究

Research on the Rule of the Grape's Fruits' Development in the Greenhouse

以大棚栽培的奥古斯特葡萄为试材,在葡萄果实生长发育期,每隔7d对葡萄果实的纵径、横径、体积、鲜重、干重进行测定,建立起相应的果实发育数学模型。结果表明:大棚栽培条件下,奥古斯特葡萄的纵径、横径、体积、鲜重发育动态均呈"慢-快-慢-快-慢"的曲线。

A mathematic model is established based on the research of the grape August including measuring its fruits＇ longitudinal diameters,transverse diameters, volumes,fresh weights and dry weights every 7 days.And the conclusion shows that the correlation of the grape August between its development status and those of longitudinal diameters, transverse diameters,volumes and fresh weights presents a dynamic wavy curve whose growing rate is ＂low-high-low-high-low＂.
