高梁(Sorghm bicolor)植株上表皮分泌的蜡质称为蜡被。根据蜡质的数量可分为重(有蜡被)、轻(少蜡被)、无渗出物(无蜡被)三种情况。无蜡被高粱对麦二岔蚜[Schizaphis graminum (Rondani))无选择抗性并呈独立遗传。无蜡被性状同耐抗性基因结 Sorghum bicolor plant epidermal secretion of wax called wax was. According to the amount of wax can be divided into heavy (wax, be light), no exudate (no wax) three cases. The wax-free sorghum showed no selective resistance to Schizaphis graminum (Rondani) and was independently inherited. No wax was trait resistant gene junction
