一、材料与方法1.材料;选树龄7年生、进入结果期第4年的美味猕猴桃(Actinidia deliciosa),雌株品种海沃德(Hayward)、雄株汤姆利(Tomuri)为材料。2.方法:选择树势中等的植株112株,随机取其32株用于试验。我们从1984年3月至1987年10月连续3年进行重复挂牌记录观察,每隔10天观察一次。用直尺、卡尺测量枝条长度、果实纵横径,然后根据纵横径用公式 V=(0.7632)/4πD~2L 换算果实体
MATERIALS AND METHODS 1. Materials: Actinidia deliciosa, Hayward, and Tomuri were selected as materials for 7-year-old aged 4 years. 2. Methods: Select 112 plants with medium vigor and 32 randomly selected for testing. We from March 1984 to October 1987 for 3 consecutive years of repeated listing observation, observed once every 10 days. Using ruler and calipers to measure the length of the branches and the vertical and horizontal diameter of the fruit, then convert the fruit body according to the vertical and horizontal diameters using the formula V = (0.7632) / 4πD ~ 2L
