Calcium is an essential macronutrient for plant growth. Although it has been shown that exogenous Ca application can increase plant resistance to abiotic stress, little is known about its potential to enhance plant tolerance to biotic stress. Here, we investigated whether pretreatment of wheat (Triticum aestivum L.) seeds with calcium chloride (CaCl₂) improves plant resistance against wheat aphid (Schizaphis graminum Rondani). The developmental time, population size, feeding behavior of aphids on plants grown from CaCl₂- and water-pretreated seeds, and plant defense responses to aphid attack were investigated.

用氯化钙引发种子增强小麦对小麦蚜虫 Schizaphis graminum Rondani 的抗性

钙是植物生长必不可少的常量营养素。尽管已经表明外源 Ca 施用可以增加植物对非生物胁迫的抗性，但对其增强植物对生物胁迫耐受性的潜力知之甚少。在这里，我们研究了用氯化钙 (CaCl ₂ )预处理小麦 ( Triticum aestivum L.) 种子是否能提高植物对小麦蚜虫 ( Schizaphis graminum Rondani) 的抗性。研究了蚜虫对由 CaCl ₂和水预处理种子生长的植物的发育时间、种群大小、取食行为以及植物对蚜虫攻击的防御反应。
