该实验的目的是研究温室中两个种植区对“Cupra”甜椒植物生长特性、生理反应和产量特性的影响。温室的两个种植区如下：中部区（CA）和北部区（NA）。 CA的日平均气温高于NA。定植后6周和12周，CA的株高、节间数和SPAD值均显着高于NA。 CA甜椒叶片净光合作用显着高于NA。 CA 种植的甜椒植株的总果实产量比 NA 种植的植株高 20%。这些结果表明，无论辣椒植物是 CA 还是 NA 种植，温室中的气温都会影响甜椒的植物生长特性、净光合作用和总产量。
The objective of the experiment was to investigate the effect of two growing areas in the greenhouse on the plant growth characteristics, physiological responses and yield attributes of the 'Cupra' sweet pepper. Two growing areas of the greenhouse were as follows, central part area (CA) and north part area (NA). Daily average temperature of the CA was higher than those of NA. Plant height, number of internode, and SPAD value in the CA were significantly higher than NA both six weeks and twelve weeks after planting. Net photosynthesis of the sweet pepper leaves of the CA was significantly higher than those of NA. The total fruit yield of the sweet pepper was 20% higher in plants grown for CA than that of NA. These results suggest that air temperature in the greenhouse influenced plant growth characteristics, net photosynthesis and total yield of sweet pepper whether pepper plants were grown as CA or as NA.
