Physical characteristics of colza seeds treated and coated with different filling materials

The knowledge about the physical characteristics of seeds, whether coated or not, is essential for the design of machines and equipment. Therefore, the objective of this work was to determine the physical characteristics of colza (Brassica napus L.) seeds coated with bentonite, gypsum and kaolin, treated with fungicide (carboxin + thiram) and aqueous extract of black pepper (Piper nigrum L.). The untreated colza seeds...

Yield and water use efficiency of cauliflower under irrigation different levels in tropical climate

The aim of the present study is to assess the effects of different irrigation blades on the growth and yield of cauliflower cv. Verona CMS. The plants were cultivated in Red-yellow Latosol during the dry period (winter-spring 2014 and 2015), in the Cerrado-Amazon transition region, Middle-Northern of Mato Grasso State, Brazil. The reference evapotranspiration (ETo) was recorded through the Class A pan method by using...

Comparative analysis of antioxidant activities of different varieties of mangos with some selected fruits

Natural antioxidants and secondary metabolites found in vegetables and fruits play significant role in human health. The juices obtained from fruits and vegetables are more convenient to consume than fresh vegetables and fruits. In the current study, the total phenolic, vitamin C, total carotene and B-carotene content and antioxidant activity of fruits and vegetables juices were determined by 1,1-diphenyl-2picryl...

Evaluation and differential expression of genes conferring drought tolerance in selected maize genotypes in the Morogoro Region of Tanzania

Experiments were conducted at Sokoine University of Agriculture in Morogoro, Tanzania to assess the growth performance and grain yield of ten maize cultivars under well-watered and water stressed conditions. The ten cultivars (CML 444, CML395, CML539, WE 4107, WE 2112, WE 3102, WE 4112 and WE 4116) obtained from Water Efficiency Maize for Africa (WEMA) project and two local market cultivars (‘STAHA’ and...

A clue for generating a new leucine-rich repeat gene in maize

Plant leucine-rich repeat (LRR) proteins play an important role in cell adhesion and signaling, neuronal development, disease resistance response and pathogen recognition. Therefore, the origin and evolution of the LRR genes had been studied deeply. However, there were no evidence of generating new LRR genes. In this study, the genomic and amino acid sequences of the LRR genes or proteins were aligned based on Maize GDB...
