PENGARUH INFEKSI TMV (TOBACCO MOSAIC VIRUS) TERHADAP PERTUMBUHAN VEGETATIF DAN GENERATIF BEBERAPA VARIETAS CABAI MERAH (CAPSICUM ANNUUM L.)

Abstract

Influence of  tobacco mosaic virus infection to vegetative and generative growth of various hot pepper varieties  (Capsicum annuum L.). This experiment was conducted to investigate the effect of TMV infection on vegetative and generative growth of various hot pepper varieties. Treatments were arranged in completely randomized design in split plot experiment with four replications. Mainplots were virus-inoculated and uninoculated plants; subplots were three hot pepper varieties: Cimerti, HP-Typhoon, and HP-Tornado. The results of the experiment showed that TMV infection caused decrease vegetative and generative growth.  The decrease of vegetative and generative growth  indicated by the reduction of leaf width, plant height, and yield.  HP-Tornado and Cimerti varieties showed susceptible reaction proved by significant reduction of the growth and yield;  HP-Typhoon was tolerance reaction to TMV infection indicated by significant reduction of the growth and lowest reduction of the yield.
