Karyotype characterization of Platostoma africanum P. Beauv. in Southeastern Nigeria

Platostoma africanum P. Beauv. is a tropical plant species valued for its efficacy in traditional medicinal system in West Africa. Although studied for its chemical properties, no cytogenetic study has been reported on this plant species. Axillary buds obtained from the growing plants were used to conduct mitotic study. Results obtained in this study showed that P. africanum is a diploid species with...

Effect of soybean (Glycine max) leaf extracts on germination and early growth of speargrass (Imperata cylindrica (L.) Reauschel

Allelopathy in plants can be instrumental in the suppression of weeds in a crop-weed interaction. Soybean has been found to exhibit allelopathetic effects by inhibiting speargrass germination and subsequent growth. The results showed that soybean and velvet bean extracts significantly reduced speargrass germination by 46 and 54% respectively. There was significant reduction in shoot and root length of speargrass by 37...

Investigation of the effect of salt stress on the antioxidant enzyme activities on the young and old leaves of salsola (Stenoptera) and tomato (Lycopersicon esculentum L.)

We can define all negative factors affecting plant growth as stress. We can say that one of the most important problems among stress factors is salt stress. Although, many researches have been done regarding the effects of salt stress, especially the different responses to salt stress among young and old leaves are being investigated nowadays. For this purpose, responses to salt stress on young and old leaves of salsola...

Yield stability of stem borer resistant maize hybrids evaluated in regional trials in east Africa

Twenty-seven stem borer-resistant maize hybrids and three checks were evaluated in 14 locations in Kenya and Ethiopia to study the genotype x environment interaction (GEI) and yield stability. An analysis of variance was conducted for grain yield, number of days to silking, plant height, ear height and grain moisture content, and reaction to turcicum leaf blight, gray leaf spot, maize streak virus diseases and common...

Effect of arbuscular mycorrhizal (Glomus clarum) and organomineral fertilizer on growth and yield performance of okra (Abelmoschus esculentus)

The influence of Glomus clarum and organomineral fertilizer on productivity of Okra was studied in a field experiment conducted in National Horticulture Research Institute (NIHORT) Ibadan. The experimental design was randomized complete block design (RCBD). There were seven treatments which were replicated three times. The arbuscular mycorrhiza fungi (AMF) and organomineral fertilizer (OMF) were applied into 6...

Determination and comparing of the essential oil components in wild and cultivated populations of Thymus kotschyanus Boiss. & Hohen

Thymus kotschyanus Boiss. & Hohen. is a grassy, permanent herb which belongs toLabiatae family and grows wild in some regions of Iran including West Azarbaijan province. In this study, variations in the quantity and quality of the essential oils of wild and cultivated populations of T. kotschyanus are reported. The aerial parts of T. Kotschyanus at the beginning of flowering stage (20%...

Validation of the use of secondary traits and selection indices for drought tolerance in tropical maize (Zea mays L.)

Breeding progress for drought tolerance in maize has been slow since drought tolerance is a complex trait controlled by many genes. Breeders improving maize for drought tolerance have therefore been using secondary traits and selection indices for selecting the best genotypes under drought stress. The objectives of this study were to determine the combining ability of the inbred lines in stress and non stress...
