Abstract

Degree of electrolyte leakage (EL) from leaf tissue after exposure to high temperature has been used as an indicator of heat tolerance. In
the present study, EL was measured in an attempt to estimate heat tolerance of Viana umbellata (Thumb.) genotypes at three different growth phases. The degree of heat injury is significantly different among the three growth phases and among the genotypes as well as their interaction. However, the degree of heat injury tends to increase over the plant growth. The 18 genotypes of V. umbellata shows moderate genetic variability as shown by its value of genetic variance (46,25 ±16,35), phenotypic variance (85,37 ±27,60), and coefficient of genetic variation (26,36%).

Keywords

toleransi/tolerance, suhu tinggi/heat, kebocoran ion/electrolyte leakage, varian genetik/genetic variance, varian fenotipik/phenotypic variance.
