Abstract

This research conducted in research farm, Faculty of Agriculture, Ciparanje, Jatinangor from October 2014 to January 2015. This research aimed to verify the competition ability on plant growth of soybean varieties due to the presence of weeds with weeding frequency. The experiment was arranged in factorial randomized block design with three replications. The first factor was soybean variety and the second factor was weed competition period. The result of this research showed that seed size from each variety of observation time 4 WAP (weeks after planting) to 10 WAP not significantly different. Each treatment on weed control in 4 WAP also not significantly different. Next observation (6, 8 and 10 WAP) showed that there were significant differences in competition point. Observation in 6 WAP showed that G6 was bigger than G5. It means that soybean was able competed with weed. Treatment G7 and G8 were higher because right time control period of weed was the best time as a plant critical period where plant was sensitive to competition getting the necessary growth factors for plant growth and yield.

Abstract

The right stage of microspore development to be used as explants become the critical factor for the successful of anther culture. Anther containing microspores at the pollen mother cell to binucleate stages were cultured on Murashige and Skoog (MS) media supplemented with various plant growth regulators. The media of 7.5 mM NAA + 0.75 mM BAP with bud size of 0.6-2.0 cm (pollen mother cell stage) are a combination that fits in callus, indirect shoot and direct shoot initiation with the percentage growth of each 30%; 16.6%; and 14.8%. Chromosome counts of root-tip cell of 89 regenerant revealed that 85 regenerant were diploids (95.5%) and 4 regenerant aneuploids (4.5%), but the haploid regenerants didn’t obtain. This result suggests that regenerants were derived from a somatic cells division.

Abstract

The yellowing disease on pepper plant (Pipper nigrum L) caused by plant-parasitic nematodes and F. oxysporum infection is a major disease in Bangka island. The wound that caused by plant-parasitic nematodes will facilitate infection into roots by the pathogen of F. oxysporum easily. This caused the plant sensitive to drought and nutrient deficiency. Utilization of endophytic microbes is one of biological control that environmental friendly and to support sustainable agriculture. The aim of this study was to explore endophytic isolates can inhibit the growth of F. oxysporum in vitro. The endophytes were isolated from bamboo root and selected their antagonistic potential against F.oxysforum by dual culture methods. The study resulted an endophytic bacteria and 13 isolates of endophytic fungi that inhibit mycelium growth of F. oxysforum. The antagonistic activity of endophytic bacteria to F. oxysforum is 28.25% by antibiosis mechanism and endophytic fungi, about 11.00-58.25% by space colonization and nutrition competition on substrate.
