PEMBERIAN AIR KELAPA SEBAGAI ZAT PENGATUR TUMBUH ALAMI PADA STUM MATA TIDUR BEBERAPA KLON TANAMAN KARET (Hevea brasiliensisMuell Arg.)
Abstract: This research aimed
to determine the effect of the concentration of coconut water as a natural
plant growth regulators in accelerating growth and getting the best
concentration on growth of rubber budded stump for several clones. This
research conducted experiments using a
completely randomized design (CRD) with 2 factors. The first factor is the
clones (K) consisting of three clones, namely PB 260, GT 1 and IRR 39. The
second factor is the concentration of coconut water (A), which consists of four
levels is without the application of coconut water, coconut water concentration
of 25%, 50% and 75%. Data were analyzed using analysis of variance and Duncan's
multiple range test at 5% level. The results showed that the main factor clones
and provision of coconut water concentration significantly affected to
parameters grow buds, plant height, stem diameter, but does not affect to
number of leaves of rubber budded stump. There is interaction between clones
with the application of coconut water concentration to parameter grow buds, but
do not interact on other parameters. Rubber clones PB 260 and GT 1 have the
better growth than rubber clone IRR 39. Application of coconut water
concentration of 50% and 75% on PB 260 and GT 1, and the application of coconut
water concentration of 25% and 50% on IRR 39 hadbetter in increasing the time
of grow buds, plant height, stem diameter and number of leaves of rubber budded
stump.
