چکیده
Penelitian ini bertujuan mengeksplorasi bakteri endofit dan mengetahui efektifitas tersebut terhadap cendawan Pestalotiopsis microspora penyebab penyakit gugur daun pada tanaman karet. Ada salah satu jenis yang serangannya meluas yaitu disebabkan oleh microspora. dapat menyerang semua klon karet sehingga mengakibatkan penurunan produksi lateks. Adanya serangan patogen kerugian secara ekonomi sangat besar. Oleh karna itu, diperlukan suatu pengendalian efektif efesiensi. biologis dengan menggunakan mikroorganisme bersifat antagonis, adanya sebagai pengendali telah menjadi alternatif untuk menghentikan peran kimiawi. Rancangan Acak Lengkap (RAL) Non Faktorial 6 perlakuan 4 ulangan, media Potato Dextrose Agar (PDA) digunakan uji antagonis in Vitro metode dual culture. Hasil analisis ragam menunjukkan bahwa Secara In Terhadap berpengaruh nyata persentase daya hambat miselium 1, 2, 3, 4, 5, Hari Setelah Inkubasi (HSI).

Eleven Hevea brasiliensis clones were evaluated for clonal stability of latex yield. A randomized complete block design was used with four replicates, two locations, seven years and three periods per year. Stability analysis was based on clone x year and clone x year x location interactions. Five stability parameters viz environmental variance, shukla’s stability variance, regression of clonal ...
متن کاملPhysiological and Molecular Responses to Variation of Light Intensity in Rubber Tree (Hevea brasiliensis Muell. Arg.)
Light is one of most important factors to plants because it is necessary for photosynthesis. In this study, physiological and gene expression analyses under different light intensities were performed in the seedlings of rubber tree (Hevea brasiliensis) clone GT1. When light intensity increased from 20 to 1000 µmol m(-2) s(-1), there was no effect on the maximal quantum yield of photosystem II (...

Inter-clonal and intra-clonal wood properties and their variations from pith to bark were evaluated for wood density and anatomical features on rubber wood (Hevea brasiliensis Muell. Arg) from a 9-year-old plantation with planting densities of 500 and 2000 trees per hectare comprised of clones RRIM 2020 and RRIM 2025. Planting density had uneven effects on wood density and wood cell features. I...
