不同整枝方式对有机基质栽培甜椒PSII光化学活性、植株生长及产量的影响
Effect of Pruning on Photochemical Activity, Plant Growth and Yield of Capsicum annuum L.var.grossum Grown on Organic Substrate
摘要
Abstract
Different pruning methods were applied on Capsicum annuum L.var.grossum grown on an organic substrate to observe their effects on the morphology, photochemical activity and yield of the plants.The results showed that the photosynthetic performance indices, PIABS andPICSm, and the driving forces, DFABS and DFCSm, were significantly greater when the 3-stem-pruningwas applied.The pruning also rendered the highest leaf PSⅡ photochemical activity among all treatments.Pruning,in general,significantly affected the plant growth.The 2-stem-pruning resulted in significantly greatest plant height, stem diameter and internode length, while the 3-stem-pruning yielded the highest root/shoot ratio.Pruning also affected the fruit count per plant and single fruit weight.The 4-stem-pruning produced the highest fruit count but lowest on single fruit weight,as the 3-stem-pruning delivereda significantly higher yield (up to 2.017 kg per plant) than the other pruning methods.In addition, the 3-stem-pruning significantly increased the soluble sugar content and sugar/acid ratio inthe fruits.关键词
