Increasing Organic Production of Summer Squash by Modulating Plant Sex Ratio
Two year experiments were carried out in open field, to study the effect of complete replacement of mineral nitrogen fertilization by organic nitrogen source (chicken manure), combined with using garlic extract as seed soaking and/or spraying seedling by ethrel, on the vegetative growth parameters, earliness, sex ratio, number of fruit/plant, total production and fruit quality, of four squash cultivars: ‘Eskandrany’ ... إقراء المزيد

COMBINING ABILITY AND NATURE OF GENE ACTION IN OKRA (Abelmoschus esculentus [L.] MOENCH)

COMBINING ABILITY AND NATURE OF GENE ACTION IN OKRA (Abelmoschus esculentus [L.] MOENCH)
Nine parental genotypes of okra were crossed in complete diallel design to study combining ability and nature of gene action for earliness and yield components. Mean squares of genotypes were found to be highly significant for all studied traits, providing evidence for presence of considerable amount of genetic variation among studied genotypes. The results showed that (P5) and (P9) were ... إقراء المزيد

Yield and Quality of Celeriac (Apium graveolens var. gapaceum M.) As Affected by Harvesting Dates and Cultivars

Yield and Quality of Celeriac (Apium graveolens var. gapaceum M.) As Affected by Harvesting Dates and Cultivars
Two celeriac cultivars (Apium graveolens var rapaceum M.) [CV Brilliant, "BC" and CV Giant Smooth Prague, "GSPC"] were assessed for yield and quality characteristics at the Experimental Farm, Faculty of Agriculture, Al-Azhar University during two successive winter seasons of 2008/2009 and 2009/2010 years. In order to investigate the effect of three harvesting dates "HD1", "HD2" and "HD3" at 120, 135 ... إقراء المزيد

Heterosis and Combining Ability for Earliness, Yield, and Fruit Quality of Some Egyptian Melon Inbred Lines via Line × Tester Analysis

Heterosis and Combining Ability for Earliness, Yield, and Fruit Quality of Some Egyptian Melon Inbred Lines via Line × Tester Analysis
Six sweet melon (Cucumis melo var. aegyptiacus) inbred lines, ‘Ana-3’ (L1), ‘Esm-4’ (L2), ‘War-4’ (L3), ‘Fal-5’ (L4), ‘Mas-4’ (L5) and ‘Kha-4’ (L6), were utilized in line × tester top crosses with three muskmelon (Cucumis melo var. reticulatus) inbred lines ‘Kur-2’ (T1), ‘Gw-4’ (T2) and ‘Hira-2’ (T3), resulting in 18 hybrids (F1) during the fall season (August-November) of 2008. The eighteen ... إقراء المزيد

Genetic and Chemical Analyses of six Cowpea and two Phaseolus Bean species Differing in Resistance to Weevil Pest

2010 | الكلمات المفتاحية Vigna unguiculata; Callosobruchus macula,
Genetic and Chemical Analyses of six Cowpea and two Phaseolus Bean species Differing in Resistance to Weevil Pest
The objective of this work was to evaluate the genetic variability among six cowpea (Vigna unguiculata) cultivars differing in their resistance to Callosobruchus maculatus (F.) weevil. Two resistant bean cultivars were used to compare between the sensitive, moderate tolerant, and high tolerant cowpea cultivars. The differentiations were performed by using random amplified polymorphic DNA (RAPD) fingerprinting, protein concentration and organic ... إقراء المزيد

Screening of Fifteen Pumpkin (Cucurbita moschata) Genotypes for Yield and Some Quality under Sohag Conditions
Eleven Egyptian landraces, two imported USA cultivars (‘Etamp’ and ‘Butternut’) and two Sudanese accessions (Khartoum and Omdurman) of pumpkin (Cucurbita moschata Duchesne) were assessed for yield and some fruit quality characteristics at the Experimental Farm, Faculty of Agriculture, Sohag University during two successive seasons, 2007 and 2008. There were significant differences among genotypes for all studied characters. ‘Butternut’ cultivar was ... إقراء المزيد

Influence of certain agricultural practices on the cowpea aphid, Aphis craccivora Koch, infesting broad bean crops and the relation between the infestation and yield of plants in upper Egypt

Influence of certain agricultural practices on the cowpea aphid, Aphis craccivora Koch, infesting broad bean crops and the relation between the infestation and yield of plants in upper Egypt
The effect of certain agriculture practices such as susceptibility of six broad bean varieties, space of planting, nitrogen fertilization levels, first irrigation and farmyard manure on the infestation of broad bean crop with the Aphis craccivora Koch was studied at El-Kawsar region, Sohag Governorate (about 495 km south of Cairo, Egypt) throughout the 2003/2004 and 2004/2005 seasons. The results obtained ... إقراء المزيد

. Developmental Analysis of Carbohydrate Metabolism in Tomato (Lycopersicon esculentum cv. Micro-Tom) Fruits

. Developmental Analysis of Carbohydrate Metabolism in Tomato (Lycopersicon esculentum cv. Micro-Tom) Fruits
Carbohydrate metabolism during the development of fruits of the tomato cultivar Micro-Tom was studied. The metabolism of the pericarp and placental tissues was found to be different. Starch was degraded more slowly in the placenta in comparison with the pericarp, whereas soluble sugars accumulated to a greater extent in the pericarp. The activities of glycolytic enzymes tended to peak at ... إقراء المزيد

. Inhibition of chloroplastic fructose 1, 6-bisphosphatase in tomato fruits leads to surprisingly small changes in carbohydrate metabolism and decreases fruit size

. Inhibition of chloroplastic fructose 1, 6-bisphosphatase in tomato fruits leads to surprisingly small changes in carbohydrate metabolism and decreases fruit size
A potato (Solanum tuberosum L.) cDNA coding for the chloroplastic isoform of fructose 1,6-bisphosphatase (cp-FBPase) was utilized to repress its activity in tomatoes (Lycopersicon esculentum Mill.) using antisense techniques. The patatin B33 promoter was used to ensure fruit specificity of the antisense effect. Transgenic plants were isolated in which fructose 1,6-bisphosphatase activity was reduced by more than 50% of the ... إقراء المزيد
