Abstract

Studies on plant development evaluating the effects of molybdenum (Mo) applications are important for nutritional management in crops, such as Physalis angulata L. crops. Therefore, the objective of this work was to evaluate the responses of Physalis angulata grown under molybdenum rates in hydroponic system. The experiment was conducted in a completely randomized design, with 12 replications and five treatments (Mo rates: 0, 0.005, 0.01, 0.015, and 0.02 mg dm-3 of H2MoO*4H2O). Chlorophyll content, gas exchange parameters, nitrate reductase activity, total protein content, dry weights of leaves, stems, and roots, and root to shoot ratio were evaluated. Supplying Mo (0.02 mg dm-3) provided gains in biomass, which is connected to the total plant weight and total chlorophyll content. The nitrate reductase activity in leaves and roots was stimulated by Mo supplementation; the highest activity was found in the roots. Photosynthetic rate (0.010 mg dm-3) and water use efficiency (0.015 mg dm-3) were favored by increases in Mo rates. The results showed that application of molybdenum as a fertilizer resulted in positive effects on biomass gain, chlorophyll content, photosynthetic rate, and water use efficiency for P. angulata plants grown in hydroponics.

水培系统中钼含量对角Physalis生长的生理响应

研究钼对作物生长发育的影响，评价钼的施用效果，对角Physalis l.l .等作物的营养管理具有重要意义。因此，本研究旨在评价水培系统中钼含量对角Physalis angulata生长的影响。试验采用完全随机设计，12个重复，5个处理(Mo浓度分别为0、0.005、0.01、0.015和0.02 mg dm-3)。测定叶绿素含量、气体交换参数、硝酸还原酶活性、总蛋白含量、叶、茎、根干重和根冠比。提供Mo (0.02 mg dm-3)可以增加生物量，生物量与植株总重量和叶绿素总含量有关。添加钼刺激了叶片和根系的硝酸还原酶活性;活性最高的部位是根部。钼用量的增加有利于光合速率(0.010 mg dm-3)和水分利用效率(0.015 mg dm-3)的提高。结果表明，施用钼肥对水培法栽培的黄颡鱼生物量增加、叶绿素含量、光合速率和水分利用效率均有积极影响。
