	<span style=\"font-size:14px;\">以37种热带型荷花为研究对象，通过测定叶片冻害指数和相对电导率来对所选品种进行耐寒能力评价与分级。结果表明，“越南食用藕”、“宁波3号”、“宁波27号”等5种热带型荷花耐寒能力最强，耐寒等级为I级；“澳大利亚莲”、“越南莲-2”、“印度莲”等15种热带型荷花耐寒能力次之，耐寒等级为II级；“越南莲-1”、“宁波19号”、“宁波24号”等8种热带型荷花耐寒等级为III级；“越南莲-4”、“泰国莲-1”、“泰国莲-10”等4种热带型荷花耐寒能力最差，耐寒等级为IV级。<br />
Thirty-seven tropical lotus varieties were selected as the research objects. The cold tolerance of the selected varieties was evaluated and classified by measuring the leaf freezing injury index and relative electrical conductivity. The results showed that “Vietnamese edible lotus root”, “Ningbo No.3”, “Ningbo No.27” and other five tropical lotus varieties had the strongest cold resistance, and the cold resistance grade was I. The cold tolerance of 15 tropical lotus species, such as “Australian lotus”, “Vietnamese lotus-2” and “Indian lotus”, was the next, and the cold tolerance grade was II. The cold resistance grade of 8 tropical lotus species, such as “Viet Nam Lotus-1”, “Ningbo No.19” and “Ningbo No.24”, is III grade. Four tropical varieties of lotus, including “Vietnam-4”, “Thai-1” and “Thai-10”, had the worst cold tolerance, and the cold tolerance grade was IV.</span>
