Abstract
This study investigated the differences in light intensity, photosynthetic efficiency, and growth characteristics of paprika plants cultivated in a semi-closed greenhouse covered with low-iron diffuse glass (SG-LDG) and a conventional greenhouse covered with low-iron regular glass (CG-LRG). There was no significant difference in light intensity between the SG-LDG and CG-LRG from the apical meristem to below 100 cm. However, below 150 cm, the SG-LDG showed higher light intensity than the CG-LRG. The light response curve and atmospheric CO2 response(A-Ca) curve, which represent photosynthetic efficiency, were not significantly affected by crop canopy differences between the two greenhouses during the early cultivation stage. However, after 12 weeks of planting, SG-LDG showed higher photosynthetic efficiency. The Jmax and Vcmax values showed no differences between the plants in the two greenhouses until 4 weeks after planting. 12 weeks after planting, plants in SG-LDG showed higher Jmax and Vcmax values than those in CG-LRG. All the growth characteristics of plants cultivated in SG-LDG were superior to those of plants cultivated in CG-LRG. Therefore, the improvement in light intensity and photosynthetic efficiency at the lower positions of plants in SG-LDG is considered to have a positive impact on crop quantity and quality.
期刊介绍:
Horticulture, Environment, and Biotechnology (HEB) is the official journal of the Korean Society for Horticultural Science, was launched in 1965 as the "Journal of Korean Society for Horticultural Science".
HEB is an international journal, published in English, bimonthly on the last day of even number months, and indexed in Biosys Preview, SCIE, and CABI.
The journal is devoted for the publication of original research papers and review articles related to vegetables, fruits, ornamental and herbal plants, and covers all aspects of physiology, molecular biology, biotechnology, protected cultivation, postharvest technology, and research in plants related to environment.
