温光胁迫对黄瓜产量和品质的影响

本试验采用4种温光管理方式,研究苗期不同温光条件对日光温室黄瓜产量和品质的影响。结果表明,低温弱光处理A(日平均温度16℃,日平均光照强度504μmol.m-2.s-1)、B(日平均温度19℃,日平均光照强度385μmol.m-2.s-1)、C(日平均温度19℃,日平均光照强度504μmol.m-2.s-1)、D(日平均温度16℃,日平均光照强度385μmol.m-2.s-1)中处理C黄瓜产量、单瓜重、果长、果粗、果皮厚度、瓜把长最大;处理C的可溶性糖、可溶性固形物含量也最高;单株结瓜数、单株分支数最小;其中单瓜重、瓜把长、单株结瓜数、单株分枝数与其他处理差异显著。

Effect of Low Temperature and Poor Light Stress on Yield and Fruit Quality of Cucumber

Four patterns of temperature and light regimes were adopted in the experiment to study effect of temperature and light on yield and quality of cucumber in energy-saving solar greenhouse.Treatments included A(daily average temperature 16℃,daily average light intensity 504μmol·m-2·s-1),B(daily average temperature 19℃,daily average light intensity 385μmol·m-2·s-1),C(daily average temperature 19℃,daily average light intensity 504μmol·m-2·s-1),D(daily average temperature 16℃,daily average light intensity 385μmol·m-2·s-1).The results indicated that C was the best according to yield,the single melon weight,the fruits length,fruits diameter,the pericarp thickness,the melon put length,the soluble sugar,the soluble solids content.The melon number per plant and the branch number per plant was the least in C.The single melon weight,the melon put length,the melon number per plant,the branch number per plant of C was significantly different from other treatments.
