Aplikasi Bakteri dalam Perlakuan Seed Coating untuk Mempertahankan Viabilitas dari Benih Cabai (Capsicum annuum L.) yang Sehat

Abstract

This research was conducted to study the effect of seed coating using Bacillus subtilis, Pseudomonas group fluorescens and Serratia marcescens toward the viability of undiseased chilli seed (Capsicum annuum L.) during storage. This study used nested design with three replications. The main plot is storage period (0, 3, 6, 9, 12, 15, 18, 21 and 24 weeks) and the subplot is seed coating treatment with bacteria (Bacillus subtilis, Pseudomonas group fluorescens, Serratia marcescens and control). Chilli seed IPB C5 still have a good viability until 24 weeks, showed from the percentage of germination that is 77.3%. Control and coating used bacteria treatment showed unsignificant difference on germination, vigour index, growth rate and normal seedling dry weight. The bacteria as coater were still alive until 24 weeks of storage periode with population 5.89 x 104 cfu g-1 for Pseudomonas group fluorescens, 4.79 x 104 cfu g-1 for Bacillus subtilis and 1.70 x 104 cfu g-1 for Serratia marcescens.
