兰竹荔枝生长及果实发育规律研究

RESEARCH ON GROWTH AND FRUIT DEVELOPMENT OF LANZHU LICHI

对兰竹荔枝生长及果实发育的研究结果表明：兰竹荔枝在贵州册亨生长迅速，３年生树高和冠径达１７０ｃｍ以上。兰竹荔枝果实发育全过程分３个阶段，需７４天左右。在果实发育过程中有３次落果高峰。果实重量增长曲线呈不明显的Ｓ型。果实发育后期可溶性固形物含量、单果重增加都很快。

An observation on the growth and fruit development of Lanzhu lichj shows it grows well in Ceheng county of Guizhou province,Its height and crown diameter are both over l70 cm in ouly 3-years after planting. And it has also been observed that the whole proceeding of fruit develop-ment can be divided into 3 stages about 74 days in total, and during this period appear 3 fruit-dropping peaks,the increasing curve of fruit weight shows slightly“S”style,In the late stage of fruit development both the soluble solids content and single fruit weight Increase rapidly.
