this study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mm nacl + cacl2 in 5:1 molar ratio) using four cvs, one british (madison) and three iranian cvs (7233-p12, 7233-p21 and 7233-p29). the plants were grown in a controlled greenhouse environment for about 18 weeks. a...

gladiolus (gladiolus grandiflorus l.), a popular bulbous cut flower, has high demand in both domestic (pakistani) as well as international markets. five potential, exotic cultivars of gladiolus, ‘cantate’, ‘corveira’, ‘eminence’, ‘essential’ and ‘fado’ were evaluated to determine the cultivar effects on yield and quality, to compare their relative performance and recommend their suitability for...

This study evaluates the effects of flooding conditions on two Okra cultivars (Ibadan local and Jokoso) at Abeokuta, Nigeria. The vary from continuous Flooding (FLD), Wetting after three Days (W3D), five (W5D), seven (W7D), andWetting ten (W10D). agronomic parameters (leaf width, leaf length, plant height, numbers leaves, area) yield data (weight, fruit diameter, length) were subjected to analy...

BACKGROUND AND AIMS The gibberellin-insensitive Rht-B1b and Rht-D1b dwarfing genes are known to reduce the size of cells in culms, leaves and coleoptiles of wheat. Resulting leaf area development of gibberellin-insensitive wheats is poor compared to standard height (Rht-B1a and Rht-D1a) genotypes. Alternative dwarfing genes to Rht-B1b and Rht-D1b are available that reduce plant height, such as ...

Leaf ecophysiological traits related to carbon gain and resource use are expected to be under strong selection in desert annuals. We used comparative and phenotypic selection approaches to investigate the importance of leaf ecophysiological traits for Helianthus anomalus, a diploid annual sunflower species of hybrid origin that is endemic to active desert dunes. Comparisons were made within and...

physiological study of wheat varieties under abiotic stress conditions is a very important factor for improving their future productions. this research work was conducted in the research greenhouse of faculty of agriculture, tarbiat modarres university in 2006, to study leaf quantitative traits of durum wheat under different levels of carbon dioxide (400 and 900 ppm), ultraviolet radiation (uv ...

to evaluate the effect of foliar application of nano iron chelate and iron chelate fertilizers on morphological traits and essential oil content of holy basil, an experiment was conducted at research farm of department of horticultural, shahid chamran university of ahvaz based on randomized complete blocks design with six treatments and three replications. the treatments were including control,...

drought is one of the most important factors limiting growth and yield in many parts of the world. in order to evaluate the effects of drought stress on some morphological and physiological traits of two cultivars of bean, two red beans (derakhshan and goli) in four drought treatments including 25%, 50%, 75%, control 100% field capacity were studied in a factorial experiment based on complete r...
