Influence of nickel ion on two species of pepper grown in two growth media
Article in Press
Different concentrations of nickel ion are released in farmlands from various environmental sources. The responses of plants in such soil vary accordingly. To determine the influence of nickel ion on plants, increasing the above named metal doses (100 and 250 ppm, including control) in pots containing two different types of soils, were used to evaluate the performance of C. frutescens and C. annuum fresh weight of fruits,...
IMPACT OF DROUGHT ON THE FOLIAR PHYSIOLOGY OF MAIZE PLANTS IRRADIATED WITH GAMMA RADIATION
Article in Press
Maize (Zea mays), a plant of economic and nutritional interest, is often confronted with unfavorable environmental conditions, including water stress. This phenomenon forces the plants to considerably reduce their production by disturbing their metabolism. Seeds of maize of the variety EV8728 were subjected to different doses of gamma radiation (100, 200 and 300 grays) in order to induce mutations in the plants that could...

Plants adapt and survive adverse environmental changes by altering their membrane lipid composition. Sesuvium portulacastrum L., a facultative halophyte has been extensively studied for its adaptability to various abiotic stresses. However, knowledge on the identification of glycerolipids and changes in their profile in coping up with the stressors is limited. In this investigation, electrospray ionization tandem mass...

This study was conducted to evaluate the physiological response of 20 maize varieties belonging to two different maturity groups under drought at seedling stage and normal growth conditions. The screenhouse experiment was laid out using randomized complete block design with three replications. Data were recorded on seedling aspect, proline and chlorophyll contents and subjected to analysis of variance to establish...
Effects of grafting on growth and development of cacao (Theobroma cacao) genotypes
Article in Press
The effects of grafting on growth, development and some functional traits in cacao genotypes was examined. Treatments were six rootstock-scion combinations of three cacao genotypes: Amelonado (A), F3 Amazon (F) and TC2 Series (T). Genotypes Amelonado and F3 Amazon formed the rootstocks for the rootstock-scion combinations (AA, AF, AT, FF, FA, FT). Data were collected on the number of leaves at two week intervals for 24...

The objective of this study was to evaluate the effect of Si supply on osmotic adjustment and solutes allocation of two sorghum cultivars either exposed or not exposed to alkalinity stress. The present study was carried out in a greenhouse at the Faculty of Science, Mansoura University, Egypt, through the two successive seasons (2016/2017) and (2017/2018). The experiment was conducted in pots to evaluate the beneficial...
Genotypic response rice (Oryza sativa L.) seedlings to salinity
Article in Press
Salinity is one of the most widespread soil problem in rice growing countries and is considered as a serious constraint to increase rice production worldwide. The experiment was aimed at assessing the response of 30 rice genotypes to NaCl stress at four salinity levels Control, 4dS/m, 6dS/m and 12dS/m at early seedling stage. The genotypic responses were compared for shoot and root length and dry and fresh weight. All...
Genetic parameters and salinity tolerance index of some rice (Oryza sativa L.) genotypes
Article in Press
Soil salinity represents an increasing threat to rice production. The success of breeding programs employing traditional screening and selection for salinity tolerance has been limited in the past decades. Phenotyping of 30 rice genotypes was done in hydroponic system using Yoshida solution and salinized at control (0 NaCl), 4dS/m, 6dS/m and 12dS/m. Seedlings were exposed to different salinity levels for 10 days. Salinity...
Tolerance of Tithonia diversifolia and Chromolaena odorata in heavy metal contaminated soils.
Article in Press
Plant growth and development were investigated from selected dumpsites and simulated-polluted soils with heavy metals were investigated using two plant species: Tithonia diversifolia (Td) and Chromolaena odorata (Co). The plant biomass capabilities in phytoremediation of this plant species had not been fully exploited in Nigeria. The effect of soil heavy metal pollution has been of global concern since plants pass these...

Diversification of crops and increasing yield is crucial to endorse food security in Ethiopia. In line with this, Shewa robit is an area where out of the major horticultural crops most of the farmers are engaged in onion production only. Hence, introduction and expansion of other horticultural crops may help to improve the livelihood of the farmers and alleviate malnutrition. To fill the gap in part, an experiment was...

Salinity stress is one of the major factors limiting agricultural production. About 20% land worldwide is subjected to salinity stress. Bean (Cv Masr-1) is an important crop occupying a large area in the world. Salt stress affects most aspects of the plant physiology and biochemistry and significantly reduces yield and limit agricultural production worldwide. In the present investigation, an attempt was made to study the...
