Periode Kritis Tanaman Cabai Merah Besar (Capsicum nnnuum L. var. long cltilli) pada Perlakuan Cekaman Air

Abstract

ABSTRACT
The critical period of red chili (Capsicum annuum L. var. long chili) under water stress
treatment. The research of the effect of water stress to the morphological characters of red
chili was conducted to understand the critical period of vegetative stage. The experiment was
arranged based on Randomized Complete Block Design, consist of 14 water treatments with 3
replications. Stressed plants were watered 500 ml each week at stress period and no stressed
plants were watered 1500 ml each week. On the first weeks all samples were watered in field
capacity. The treatments i.e. Control plants were watered during 1-14 weeks; Plants were
treated in stress period respectively at ages 2 weeks; 2-3 weeks; 2-4 weeks; 2-5 weeks; 2-6
weeks; 2-7 weeks and continued watering; Plants were watered at field capacity during 2-7
weeks, 2-6 weeks; 2-5 weeks; 2-4 weeks; 2-3 weeks and 2 weeks, and continued stress
period treatment; Plants were treated in stress period during 2-1 4 weeks. The result showed
that (i). Water stress treatments were significantly increase roots length; reduce length and
weigl~t of stem; number, area and weight of leave. (ii). Red chili plants at vegetative stage
were more resistant to water stress compared with reproductive stage according to stem and
leave parameters.
