Abstract

ABSTRACT Effectiveness of Technique Extraction Test and Dry Heat Treatment to Seed Health of Chili Pepper (Capsicum frutescens L.). Chili (Capsicum frutescens L.) is one of the horticultural crops of the Solanaceae family that has a high economic value. Seed healty problems is one of the chili pepperproduction constraints. Chili seeds used by farmers mostly contaminated by seed-borne diseases such as viruses. This study aims to determine the effectiveness of seed extraction techniques and Dry Heat Treatment (DHT) in producing healthy red pepper seeds in a seed source trials of healthy plants and diseased plants. The design used in this research is completely randomized design (CRD) with 2 factors. The first factor was the extraction technique which consisted of three levels ie extraction technique using 2% HCl, extraction techniques using quicklime and extraction techniques using water. The second factor was DHT with 2 levels ie DHT and without DHT (NDHT). The results of this research showed that DHT treatment was effective in producing healthy chili pepper seedlings with healtinese 100%, while seed extraction techniques has not been effective to produce healthy red pepper seeds with a percentage of less than 90%. Interaction between extraction techniques and DHT on trial seed originating from sick plants showed real influence. Keywords: chili pepper, extraction techniques, Dry Heat Treatment, healthy seed

Abstract

ABSTRACT Effect of Various Timing on Bud Cutting as Cuttings Material and Dosage of Rootone F on the Growth of Vanilla Short-Cutting (Vanilla planifolia Andrews) Vanilla (Vanilla planifolia Andrews) can generally be propagated by seed (generative) and vegetative by cuttings. As the multiplication by seed takes longer to flowering, thus the vanilla propagation for commercial purpose is done by cuttings. This study aims to determine the effect of time on bud cutting as cuttings material and dosage of Rootone F as well as its interactions on the growth of vanilla short-cuttings. This study uses two factors factorial design, i.e.: time on bud cutting as cuttings material and dosage of Rootone F. The result of the research showed an interaction between time on bud cutting as cuttings material and dosage of Rootone F provides a very significant effect on the variable of oven dried stems shoots weight, and showed a significant effect on the variable total oven dry weight; while other variables showed no significant effect. Treatment of time on bud cutting as cuttings material (P) showed highly significant effect on the variable of time to sprout, while the other variables showed no significant effect. Dosage of Rootone F (D) showed no significant effect on all variables. The interaction of time on bud cutting as cuttings material 8 days before planting with Rootone F dose of 100 mg / 1 ml of water provides a better growth of vanilla short-cuttings with the highest total oven dry weight is 1,12 grams and has increased 89.83% compared to the bud cut when the cuttings is about to be planted and Rootone F dose of 0 mg / 0 ml of water. Keywords: Vanilla time on shoot-cutting as cuttings material, Rootone F, nurseries, vanilla.
