Sixty five methanolic extracts of Sumatran rainforest plants representing 63 species of 21 families were assayed in vivo for antinematodal activity against Bursaphelenchus xylophilus using our cotton ball-fungal mat method. Extracts of 27 plants species from 14 families exhibited antinematodal activity, while 37 species were inactive. Among them, three extracts of Bischofia javanica, Knema hook...

Accurate normalization of gene expression data is an absolute prerequisite to obtain reliable results in qPCR analysis. Oenanthe javanica, an aquatic perennial herb, belongs to the Oenanthe genus in Apiaceae family, with known medicinal properties. In the current study, O. javanica was subjected to hormone stimuli (gibberellin, salicylic acid, methyl jasmonate, and abscisic acid) and abiotic st...

Kitosan merupakan senyawa alami, non toksik dan sudah banyak digunakan dalam industri makanan maupun farmasi. dapat diperoleh dari hasil isolasi cangkang kreca (Bellamya javanica). memiliki berbagai aktivitas seperti antitumor, neuroptotektif, antiinflamasi, antijamur antibakteri. Aktivitas antibakteri kitosan Bellamya javanica belum diketahui sebelumnya, sehingga penelitian ini dilakukan untuk...

Excised tomato roots infected with Meloidogyne javanica produced ethylene at 3-6 times the rate of noninfected roots. This increase in ethylene production started 5 days after inoculation. Gall growth and ethylene production in infected roots were accelerated by 1-aminocyclopropane-1-carboxylic acid (ACC), indole acetic acid (IAA), and ethrel known as ethylene production stimulators. When inhib...

Pasteuria penetrans will build-up faster where there is a high initial nematode density and can suppress root-knot nematode populations in the roots of tomato plants. The effect of different initial densities of nematode (Meloidogyne javanica) (150, 750, 1500, 3000) and P. penetrans infected females (F1, F3) densities (F0=control and AC=absolute control without nematode or P. penetrans inoculum...

Toprak, bitki paraziti kök-ur nematodlarının çoğalmaları ve varlıklarını sürdürmeleri için iyi bir gelişme ortamıdır. Bu çalışmada, Gaziantep Osmaniye il ilçeleri sebze alanlarındaki Meloidogyne incognita, M. javanica, arenaria luci türleri ile bulaşık olan toprakların tekstürü (Suyla Doygunluk (%), pH’ı elektriksel iletkenliği (EC)) incelenmiştir. Çalışma sonunda dört nematodu türünün bulunduğ...
