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.
