温室与露地无核早红葡萄果实生长动态比较研究

试验于2004年分别对温室和露地无核早红葡萄果实生长发育动态进行了观测,对正在膨大的葡萄果实的纵径和横径进行定期测量记录并得出其生长曲线。研究结果表明:①该品种果实生长呈双S曲线:初始快速生长期、缓慢生长期和第二次快速生长期。②温室葡萄第一个快速生长期果实生长速度明显快于第二个,果实纵径的生长缓慢期与第二个快速生长期的界限不明显;幼果第一个快速生长期纵径生长速度明显快于横径,在第二个快速生长期横径快于纵径,但是总的生长量纵径大于横径,果粒最后基本呈圆形。③露地葡萄在果实的第一个快速生长期和生长缓慢期的纵横径生长曲线基本相同,横径较快地进入第二个快速生长期并且生长速度要快于纵径,导致果实最终横径略大于纵径,果粒略呈扁圆形。

The Comparative Study of the Fruit of 8611 Grape Growth Development Dynamics Grown in Greenhouse and Open Field

This experiment observed the fruit of 8611 grape growing development dynamics which separately growed in greenhouse and open field in 2004.We measured and noted the vertical diameter and horizontal diameter to the growing grape.The result indicated that the development of grape berry which grew in greenhouse and open field both present doubles S curve.The speed of fruit development in first developing was obviously faster than that of the second one.The limit of slow period of fruit development and second developing fastigium illdefined.The developing speed of verti-ca diameter of geenhouse 8611 grape faster than horizontal diameter obviously.But horizontal diameter more faster in the second developing fastigium.The vertica and horizontal diameter development curve of open field 8611 grape are i-dentical basicly which in first developing fastigium and second one.Horizontal diameter went into the second fastigium more quickly and more developed more faster than the vertical diameter.It lead to vertical diameter longer than hori-zontal diameter a little.
