Studies on the resistance of rice to the leaf and plant hoppers


, : Studies on the resistance of rice to the leaf and plant hoppers. Research Report of the Office of Rural Development, Soil Science, Fertilizer, Plant Protection and Micrology, S Korea Nong sa Si hem Yen ku Po ko To Yang Bi Ryo, Jak Mul Bo Ho, Kyun I Pyun 16: 11-20

About 400 varieties, IRRI strains and newly-developed lines were tested against five species. Ten forms were resistant to Laodelphax striatellus, eleven to Nilaparvata lugens, three to Sogatella furcifera, ten to Nephotettix cinticeps and four to Inazuma dorsalis.

Acidification of blood entering a membrane lung (ML) with lactic acid enhances CO2 removal (VCO2ML). We compared the effects of infusion of acetic, citric, and lactic acids on VCO2ML. Three sheep were connected to a custom-made circuit, consisting...

Aim: To evaluate promotive effect of hyperthermia on the carcinostatic activity of synthesized ornega-hydroxy fatty acids (wHFAs) and their ethylesters agaist Ehrlich ascites tumor (EAT) cells. Methods. EAT cells were cultured with either omega H...
