摘　　要：对河南省信阳市引种的2个猕猴桃(Actinidia chinensis Planch)新品种东红和金艳以及本地品种的物候期、生长节律进行了调查。结果表明,2个猕猴桃品种与信阳市原有猕猴桃品种物候期不同,增加了品种的多样性;2个品种的生长期约245 d,4月中旬至9月中旬生长量较大,占总生长量的85%以上;依据地径净生长量可将猕猴桃生长期划分为3个时期,即生长前期、速生期、生长后期;用直线模型和Logistic曲线对地径生长进行拟合,结果均达极显著水平。The phenophase and growth rhythm of two introduced kiwifruit(Actinidia chinensis Planch)varieties and local variety in Xinyang city,Henan province,was investigated.The results showed that the phenophase between two kiwi fruit varieties and local variety of Xinyang was different,which increased the varieties of diversity.These two kiwifruit varieties growing period of about 245 d,growth in the middle of April to the middle of September was larger,more than 85%of the total increment.Kiwifruit growth period can be divided into three periods,namely the growth,fast-growing period,at later growth stage.Using the linear model and Logistic curve fitting,have reached extremely significant level.
