KETAHANAN LIMA VARIETAS TANAMAN CABAI RAWIT (Capsicum frutescens L.) TERHADAP INFEKSI TMV (TOBACCO MOSAIC VIRUS) PADA UMUR TANAMAN YANG BERBEDA

Abstract

Diseases caused by TMV (Tobacco Mosaic Virus) on chili is important to note because it can cause a loss. Chili varieties are currently circulating in the market and have not been evaluated resistance to TMV (Tobacco Mosaic Virus). Therefore, research is needed on the effects of the attack TMV (Tobacco Mosaic Virus) on the growth, production and resistance to chili varieties such. The initial symptoms are the same, namely the emergence of a mosaic on the leaves of young plants, followed by chlorosis due to reduced chlorophyll content of plants for photosynthesis disturbed then a widespread and causes the leaves begin to show symptoms of the malformation. Leaves of the plant having malformations (leaves shriveled). The results showed that TMV infection can suppress plant growth and decrease crop production. Treatment plant inoculation at different ages apparently significant effect on plant growth as well as production plants. Chili plants infected with virus at a very young age the rate of plant growth and development is inhibited, so the plants will grow abnormally. Based on the parameters used to calculate the resistance category chili tested against TMV virus showed that the varieties are very susceptible Sonar and Bara, Cakra susceptible, moderately resistant while TM Rawit, Samaru resistant to TMV infection.
