Abstract

ABSTRACT In this study, red and yellow varieties of djulis (Chenopodium formosanum Koidz) were cultivated in spring and autumn, and the effects of calcium carbonate treatment on their growth traits, antioxidant capacity, and grain maturation were examined. This study showed that calcium carbonate treatment increased the plant height and stem thickness in the red variety of djulis. The treatment also significantly increases the yield components of the red variety of djulis, such as spike length and thousand-grain weight. Treating the red variety of djulis with calcium carbonate in spring significantly increased the antioxidant enzyme activity such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR) activities. Interestingly, results indicated that calcium carbonate treatment could promote the early maturation of the mid-late-maturing red variety of djulis and delay the maturation of the early-maturing yellow variety. Hence this experiment concludes that the exogenous calcium treatment in djulis can regulate grain maturation and promote growth, yield, and antioxidant enzyme activity; however, the growing season and the varietal effects play a vital role in determining the overall productivity of the djulis crop.

外源钙肥对台湾藜生产期的调控作用

摘要以春季和秋季栽培的红、黄两种荔枝(Chenopodium formosanum Koidz)品种为试验材料，研究了碳酸钙处理对其生长性状、抗氧化能力和籽粒成熟度的影响。本研究表明，碳酸钙处理增加了红色品种朱丽的株高和茎粗。该处理还显著提高了红色品种大枣的穗长和千粒重等产量成分。春季碳酸钙处理显著提高了红枣的超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、抗坏血酸过氧化物酶(APX)和谷胱甘肽还原酶(GR)活性。结果表明，碳酸钙处理能促进中晚熟红色品种早熟，延缓早熟黄色品种成熟。综上所述，外源钙处理可调节玉米籽粒成熟，促进生长、产量和抗氧化酶活性;然而，生长季节和品种效应在决定朱石作物的整体生产力方面起着至关重要的作用。图形抽象

期刊介绍： Plant Production Science publishes original research reports on field crops and resource plants, their production and related subjects, covering a wide range of sciences; physiology, biotechnology, morphology, ecology, cropping system, production technology and post harvest management. Studies on plant production with special attention to resource management and the environment are also welcome. Field surveys on cropping or farming system are also accepted. Articles with a background in other research areas such as soil science, meteorology, biometry, product process and plant protection will be accepted as long as they are significantly related to plant production.
