Two field experiments were carried out during the summer seasons of 2000 and 2001, at the Experimental station Farm, Faculty of Agriculture, Alexandria University, at Abies, to investigate the response of potato plants cv. Alpha, to two biofertilizer types (Nitrobein and Halex-2) under four varying percentages NPK; 25%, 50%, 75% and100% from the commercial recommended rates (180-60-96 Kg N-P-K ...

UV-B radiation and EOD light (EOD) quality has both signaling and damaging effects based on the dosage and time of exposure. At highland areas UV-B decreases crop productivity and also light quality increase at high elevation area but EOD light quality effect was not researched based on altitude. Therefore, in the present study a field experiment was conducted to investigate the effects of UV-B...

Greenhouse experiment was conducted for four months using Leucaena leucocephala and Pleurotus tuber-regium to determine their bioremediation potentials. Leucaena leucocephala, Pleurotus tuber-regium and Leucaena leucocephala combined with Pleurotus tuber-regium were tested for their ability to improve nutrient (N, P, K, total organic carbon) and reduce heavy metals (Zn, Ni, Pb, Cu) of soil poll...

The aim of the present study was to get somaclonal variants and induced mutants of potato for desirable characters with special emphasis on yield and yield components in two cultivars of potato viz., Desiree and Diamant. Inter-nodal explants from both the cultivars were incubated for 1420wks in callus inducing medium comprising MS salts supplemented with NAA (1.0mg/l) and BAP (0.5mg/l) for obta...

Pinellia ternate (Thunb.) Breit (Araceae) is a shade-tolerant perennial medicinal plant, but its optimum light intensity is not sufficiently known. Hence, the influence of light intensity on the physiological responses, growth and secondary metabolic products in P. ternata under four light conditions (15%, 25%, 45% and 100% of full sunlight) in a greenhouse were to be investigated. The results ...

ADPglucose pyrophosphorylase has been extensively purified from potato (Solanum tuberosum L.) tuber tissue to study its structure. By employing a modified published procedure (JR Sowokinos, J Preiss [1982] Plant Physiol 69: 1459-1466) together with Mono Q chromatography, a near homogeneous enzyme preparation was obtained with substantial improvement in enzyme yield and specific activity. In sin...

abstract in order to investigate the effects of nitrogen fertilizer levels on the yield and quality of potato, (solanum tuberosum l.) a field experiment was conducted based on randomized complete blocks design with 3 replications in the research field of the college of agriculture, ferdowsi university of mashhad. nitrogen topdress fertilizer was applied in two levels of 100 and 150 kgn.ha-1 and...

Effects of nitrogen on the leaf chlorophyll (chl), yield and yield attributing characters of potato as tuber number and mean tuber weight were studied. Correlation coefficients between the investigated characters were determined. Five nitrogen rates (0, 150, 200, 250 and 300 kg/ha) and four potato cultivars (Burren, Slaney, Anna and Emma) were used in the study. First, second, third class tuber...

Different doses of ethanolic extract of Stephania glabra tuber were evaluated for antihyperglycemic activity in alloxan induced diabetic mice. The oral administration of 100, 200 and 500 mg/kg body weight showed significant hypoglycemic activity. Glibenclamide (oral hypoglycemic agent, 25 mg/kg, p.o.) has been used as standard.
