Mitochondria isolated from potato (Solanum tuberosum L.) tuber were investigated for the presence of a nicotinamide nucleotide transhydrogenase activity. Submitochondrial particles derived from these mitochondria by sonication catalyzed a reduction of NAD(+) or 3-acetylpyridine-NAD(+) by NADPH, which showed a maximum of about 50 to 150 nanomoles/minute.milligram protein at pH 5 to 6. The K(m) v...

Dietary patterns represent a broader picture of food consumption, and are better correlated with a variety of health outcomes. However, few studies have been conducted to explore the associations between dietary patterns and obesity in Southwest China. Data from the 2010-2012 National Nutrition Survey in the province of Yunnan, Southwest China, were analyzed (n = 1604, aged 18-80 years). Dietar...

in order to find the most effective concentration of 6-banzilamino purine (bap) and cycocel (ccc) on microtuber production of two potato cultivars under tissue culture conditions, a factorial experiment was carried out with randomized compelete design with 4 replications. four levels of bap (0, 5, 10 and 15 mg l-1) and four levels of ccc (0, 250, 500 and 1000 mg l-1) were applied on two potato ...

The aim of this study was to explore the effects of different density treatments on potato spatial distribution and yield in spring and fall. Plant density influenced yield and composition, horizontal, and vertical distribution distances between potato tubers, and spatial distribution position of tuber weights. The results indicated that: (1) Spring potato yield had a convex quadratic curve rel...

Shallots (Allium ascalonicum L) is an important vegetable plant as a kitchen spice. and traditional medicine. The productivity of shallots in Riau still low, due to low soil fertility. For this reason, fertilization carried out by combining liquid organic fertilizer with water hyacinth potassium nitrate (KNO3).
 aim study was determine the main interaction influence POC Water Hyacinth KNO3...

BACKGROUND Potato frying quality is a complex trait influenced by sugar content in tubers. Good frying quality requires low content of reducing sugars to avoid the formation of dark pigments. Solanum tuberosum Group Phureja is a valuable genetic resource for breeding and for genetic studies. The sugar content after harvest was analyzed in a germplasm collection of Group Phureja to contribute to...

Abstract To contribute to the development of a novel cropping system for potato grown from greenhouse-derived seedlings hybrid true seeds, planting density trials were carried out under normal Dutch agronomic conditions. For two consecutive years, 5-week-old experimental genotypes transplanted into farmers’ production fields at contrasting locations: flat-bed on sandy soil and traditional ridge...

Various farm wastes were investigated as substrates for Pleurotus tuber-regium. The highest mushroom harvest (fresh weight) was obtained from oil palm fruit fiber substrate and the lowest yield was from yam (Dioscorea sp.) peelings. Casing enhanced yield from all substrates. Oil palm fruit fiber spawn is an alternative to the sclerotium in propagating the fungus. Some fungi and pests were assoc...

The potato tuber moth, Phthorimaea operculella (Zeller), in tropical and subtropical countries, is the most destructive pest of potato, Solanum tuberosum L. The larvae attack foliage and tubers in the field and in storage. The purpose of this study was to evaluate the efficacy of a Bt-cry5 transgene to control the potato tuber moth in tuber tissues. Tuber bioassays using stored (11-12 mo old) a...

We screened the pharmacological effects of a 50% ethanol extract of Yacon tubers and leaves on spermatogenesis in rats. As a result, we found that Yacon tuber extracts increased sperm number and serum testosterone level in rats. It has been reported that the crude extract of Yacon tubers and leaves contain phenolic acids, such as, chlorogenic acid, ferulic acid and caffeic acid by HPLC/MS analy...
