Abstract:

Cowpea, Vigna unguiculata (L.) Walp is an excellent source of protein, vitamins and minerals and a major food crop many parts of Africa. Optimal production levels are hampered by insect pests and diseases. Biotechnological techniques such as tissue culture and genetic engineering can aid in the development of varieties with resistance to insect pests and diseases. The objective of this study was to investigate conditions necessary for the development of a reproducible tissue culture system that can be applied to regenerate transformed cells from culture.

Abstract:

A novel alteration in secondary metabolism of maize transformed with wheat oxalate oxidase gene (OXO) was determined using HPLC and microscopy. Phenolic concentration was significantly increased, but DIMBOA synthesis was down-regulated. The high levels of soluble phenolic acids, in particular free ferulic acid, most likely contributed to the insect resistance in the OXO maize. To facilitate future cowpea transformation with the OXO, a stable in vitro regeneration system was established in blackeye cowpea via shoot organogenesis. The optimal initiation medium comprised MS salts, B 5 vitamins,

Abstract:

Water Stress caused reduction of seed yield in cowpea plants by decreasing total biomass and photosynthesis. The source leaf, pod and seed water potential of stressed cowpea were lower than water potential in non-stressed plants. No differences in water potential and turgor were observed between pod walls and seed of cowpea plants. Partitioning of the total above ground dry matter was similar for both stressed and nonstressed cowpea plants. Photosynthetic rates of single leaves from cowpea were greater for nonstressed than stressed plants. The duration of seed growth of cowpea was not differen

Abstract:

Examination of the imbibition characteristics of eighty chickpea genetic lines (53 Desi and 27 Kabuli types) and eleven cowpea cultivars revealed that in both species seeds with unpigmented testae imbibed more rapidly than the pigmented seeds. Rapid imbibition was associated with high solute leakage, indicative of possible imbibition damage. Further evidence of imbibition damage was revealed in cowpea where the rapidly imbibing unpigmented seeds had poor vital staining with tetrazolium chloride after 24h imbibition. In chickpea, all the genetic lines of white Kabuli seeds had similar rapid rat

Thesis (MScAgric) -- University of Stellenbosch, 2003.<br>ENGLISH ABSTRACT: Cowpeas are produced under low and irregular rainfall in most of arid and semi-arid areas of sub-Saharan Africa. Growth and yield are therefore reduced due to the occurrence of water stress during the growing season. Knowledge of the responses and adaptive mechanisms of cowpeas to water stress may help to improve the management practices for these areas. Therefore, three glasshouse experiments were conducted at Welgevallen Experimental Farm of the University of Stellenbosch to test the responses of two cowpea cu

Abstract:

Cowpea (Vigna unguiculata) is an edible annual leguminous crop cultivated by many subsistence and rural communities in developing countries in subtropical areas of the world. Cowpea is a very versatile, well adapted and nutritious grain legume. However, cowpea seed is prone to fungal infestation under suboptimal storage conditions. Some of these fungi, including Aspergillus and Fusarium spp., produce their associated mycotoxins under these conditions. Fumonisins are produced primarily by Fusarium verticillioides and F. proliferatum and are known to be toxic to vertebrates and plants. Fumonisin

Abstract:

These studies were conducted to determine the response of cowpea cultivars differing in seed coat colour to storage and reduced water availability during germination, and to relate these to the chemical composition of their seed coats. Seeds of five cowpea cultivars were stored under simulated tropical conditions (30°C/75.5% r.h.) for 6 months, subjected to accelerated ageing (40°C/100% r.h.) for 6 days or controlled deterioration (40°C/20% m.c.) for 4 days. Unpigmented seeds showed more rapid deterioration which was revealed by low germinations, high leachate conductivity and poor

Introdução: As doenças cardiovasculares representam a principal causa de morte no mundo, sendo o aumento da concentração de colesterol sanguíneo um dos seus principais fatores de risco. O processo aterosclerótico envolve não apenas a deposição de colesterol nas artérias, mas a inflamação tem papel central em todas as fases do processo aterosclerótico. Estudo em animais mostrou, por sua vez, que a proteína de feijão caupi é um potente redutor na concentração de colesterol sangüíneo.

Esta pesquisa teve como o objetivo estudar a influência da temperatura e da umidade relativa do ar (UR) nos aspectos biológicos da mosca-minadora, Liriomyza trifolii (Burgess, 1880), em feijão caupi [(Vigna unguiculata (L.) Walp.)], para fornecer subsídios a futuros projetos de controle biológico desta praga. Verificou-se uma relação inversa entre a duração de desenvolvimento e o aumento da temperatura na faixa de 15 a 32°C. A viabilidade larval não foi afetada na faixa térmica estudada, enquanto a 32°C houve uma alta mortalidade da fase de pupa. O limiar térmico inferior de desenvolvimento ob
