Abstract

The research about impact of using barrier of net color (red and white) for whitefly population on cayenne pepper plant in Kerta Village was conducted in order to know firstly about species of whitefly that existing on the cayenne pepper, secondly to know about impact of net color for populations of whitefly on the cayenne papper. The research was done using the randomized block design (RBD) with 3 treatments and 9 replications. The observation covered of the population of whitefly and symptom of virus infection. The results of this research showed whitefly were identified as Bemisia tabaci. The result indicated the lowest average populations of Bemisia tabaci occurred in the white net barrier treatment.

Abstract

Chili peppers (Capsicum frutescens L.) is one of the important vegetable in the world and one of the leading horticultural commodities in Indonesia. Pepper plants grown in all provinces in Indonesia and got priority for development because it has great potential economic value. These researches was conducted in order to determine the type of infecting Potyvirus on chili and know the proximity nucleotide sequence of Potyvirus infecting chili crop in Kerta village, Payangan, Gianyar, Bali, with the kind of Potyvirus in other areas. This study use RT-PCR technique to detect plant viruses and continued with tracing sequence coat protein gene nucleotide to its proximity to some of the isolates analyzed from GeneBank. The results showed that the infecting Potyvirus chili crop is Chili veinal motle virus species (ChiVMV) with size of approximately 900 bp DNA band, and based on phylogenetic analysis of coat protein gene nucleotide sequence, PayanganIndo isolate had high similarity (93%) and small genetic distance (0.041) with isolate of origin Thailand state.

Abstract

The aims of this experiment were to compare the shelf life of chili pepper seeds given dry heat treatment (DHT) and non dry heat treatment (NT). This experiment was conducted in Laboratory of Seed Technology Faculty of Agriculture, Udayana University. The study consisted of two experiments that attempt to use lots of chili seeds treated with dry heat treatment (DHT) and experimental use a lot of chili seeds without dry heat treatment (NT). This experiment uses a randomized completely design (RCD) with 10 replications.  Each type of chili pepper seeds tested each power shelf with 10 replications. Storage treatment performed at room temperature, which consists of non-storage (T0), storage for 2 weeks (T2), storage for 4 weeks (T4), storage for 6 weeks (T6) and storage for 8 weeks (T8). Thus, for each lots of chili pepper there are 50 experimental units. Treatment until 8 weeks of storage time did not affect the viability and vigor of pepper seeds either DHT or NT with value up to 80%, so they do not affect seed longivity.  The dry heat treatment (DHT) showed the values of seed and seedling vigor are higher compared to that of no dry heat treatment (NT).
