Leaf size and shape play important roles in agronomic traits, such as yield, quality and stress responses. Wide variations in leaf morphological traits exist in cultivated varieties of many plant species. By now, the genetics of leaf shape and size have not been characterized in Brassica napus. In this study, a population of 172 recombinant inbred lines (RILs) was used for quantitative trait lo...

puccinia recondite (leaf rust) is an endemic disease in iran; this disease can affect the productivity and quality of wheat, that occurring in all wheat growing regions. genetic resistance to leaf rust of wheat is the most important strategy to control the diseases and 51 leaf rust resistance genes (lr gene) are reported in wheat to provide resistance to leaf rust. this study aims to identify p...

Pruning is crucial to balance productivity and fruit quality in blueberry orchards. Slight, conventional and severe pruning treatments were applied on 4and 5-year old bluberry plants cultivar ‘Brigitta’ to evaluate their effect on yield, leaf area, gas exchange and fruit load as driver of fruit quality traits. Yield and berries per plant decreased with increasing pruning severity, whereas canop...

Rising atmospheric carbon dioxide has the potential to alter leaf litter chemistry, potentially affecting decomposition and rates of carbon and nitrogen cycling in forest ecosystems. This study was conducted to determine whether growth under elevated atmospheric CO2 altered the quality and microbial decomposition of leaf litter of a widely distributed northern hardwood species at sites of low a...

Long-term effects of light quality on leaf hydraulic conductance (K(leaf)) and stomatal conductance (g(s)) were studied in cucumber, and their joint impact on leaf photosynthesis in response to osmotic-induced water stress was assessed. Plants were grown under low intensity monochromatic red (R, 640 nm), blue (B, 420 nm) or combined red and blue (R:B, 70:30) light. K(leaf) and g(s) were much lo...

introduction: in iran, tuberose is ranked the forth after gladiolus, rose and carnation. these flowers are known as high quality products among which maximum exportation belongs to tuberose and gladiolus. in plant cultivation and development, adequate provision of nutrients is of crucial importance. tuberose needs plenty of nutrients to obtain the desirable quality and flowering. hence, tuberos...

Background and objectives: Tapinanthus globifer is a semi-parasite plant that mostly grows on the branches of the host tree species of the genera Vitellaria, Kola, Citrus, Combretum, Acacia, and Terminalia. The leaf is known for its use in traditional medicine to treat inflammations, malaria, headaches, bacterial infections, ulcers and diabet...

BACKGROUND 'Vrikshayurveda', an ancient science of plant life described by Surapala, has clearly outlined a systematized agricultural practice that insisted on the use of Kunapa jala (KJ) and Pancha gavya (PG) to enhance the yield and quality of plants. OBJECTIVE An experiment was conducted to evaluate the effect of KJ and PG on growth, physiological, biochemical, quality attributes and yield...
