Abstract

Salak has the scientific name Salacca zalacca including a low-growing family of palms. This seasonal fruit plant is a type of horticulture that has the potentioal to become an axport commodity in Indonesia. In East Java, especially in Lumajang, Madura and Kediri are areas that produce salak commodities. Morphological identification aims to obtain basic traits so that the appearance or phenotype of each accession can be distinguished quickly and easily, by estimating how much genetic diversity it has. This study aims to determine the morphological characters and to determine the salak kinship of Lumajang, Kediri and Madura. The result of phylogeny analysis of the Salacca zalacca kinship in East Java show that the results of the kinship analysis of the salak in the Lumajang, Kediri and Madura areas formed 2 large groups or cluster. So it can be concluded that the Salacca zalacca originating from the Lumajang, Kediri and Madura areas still come from the same ancestor. This can be seen from the value of kinship distance, the morphological identificaion equation. In addition, environmental factors can also affect the morphology of plants. Sunlight intensity, N and P nutrients can also affect the difference in leaf color

Abstract

Blast disease is an important disease that affects many rice plants. Blasts can damage rice leaves (leaf blasts), nodes (node blasts), neck blasts, colar blasts and rice grains. Symptoms on the leaves are rhombic-shaped spots with a tapered tip. The center of the patch is gray surrounded by brown to reddish brown on the edge of the spot. The color of the spots at the beginning of the symptoms is white or gray, surrounded by green-brown. Based on market demand, agricultural products that are safe and healthy for consumers as well as environmentally friendly are increasing, therefore controlling plant pathogens by using antagonistic microorganisms is one of the ways that must be considered. A number of microbes have been widely tested and are quite effective in controlling plant pathogens. PGPR and Streptomyces are biological agents that are able to reduce the level of attack of plant diseases, especially in rice blast disease. This study used a comparative method between rice cultivation and biological agent applications and rice cultivation without biological agents or control plant applications. The results obtained indicate that the application of biological agents can reduce the percentage of disease severity, reduce the percentage of infected leaves, the biological agents are also able to extend the incubation period, increase plant height growth, number of tillers and also the number of grains per panicle.
