Heat stress during reproductive stages has been leading to significant yield losses in chickpea ( Cicer arietinum L.). With an aim of identifying the genomic regions or QTLs responsible for heat tolerance, 187 F 8 recombinant inbred lines (RILs) derived from cross GPF 2 (heat tolerant) × ILWC 292 sensitive) were evaluated under late-sown irrigated (January-May) and timely-sown environments (Nov...

Abstract One of the causes generally low upland rice productivity in Indonesia is fertility and soil pH. The use genotypes with high yielding capacity tolerant acid soils can increase productivity. This study aimed to develop an early efficient selection method, determine research was conducted using a seed germination technique on paper medium varied acidity level (pH 6.5, 5.5 4.5). Research d...

AIMS A major problem in industrial fermentation of organic acids with micro-organisms is to ensure a suitable pH in the culture broth. To circumvent this problem, we investigated the effect of citrate, which is a widely used auxiliary energy co-substrate, on cell growth, organic acid production and pH homeostasis among extracellular environment, cytoplasm and vacuole, in the pyruvic acid produc...

Two freshwater and two marine alg;tl species were grown in intensive contiimous cultures at a fixed dilution rate of 0.5 ·day -I, but at varying pH levels in the range 7.6 to 1C.6. Both freshwater species, Scenedesmus obliquus (Turp.) Kutz. and Chlorella vulgaris Beij., grew up to pH 10.6 although C. vulgaris was more adversely affected by alkaline pH than was Scenedesmus obliquus. Of the marin...
