FENOFISIOLOGI PERKECAMBAHAN DAN PERTUMBUHAN BIBIT DUKU(The Phenophysiology Of Germination and Growth Of Duku Seedling (Lansium Domesticum Corr.))

Abstract

This research was conducted to evaluate the Duku germination and its growth.
Research used descriptive analysis to examine Duku’s germination. To make
duku germinated it used six tubs that used sand as media. After fourth week
germination, the seedling was transplanting into polybags. The polybags media
used soil with organic manure. The parameters that observed are percentage of
germination, percentage of normal and abnormal seedling, percentage of
polyembrioni seedling, root and shoot growth. The result showed that the
amount of normal seedling 80 %, abnormal seedling 20 %, and polyembrioni 25
%. Duku seedling grows normally until six weeks after germination are 40 %
and Duku Seedling with uniform growth after six months about 20 %.
Key words : Seed, poliembriony, vigor.
