In order to determine the effect of plant density on yield and qualitative traits of four genotypes of sunflower (Helianthus annuus L.) an experiment was conduct in Research Farm of Kabotar Abad, Isfahan province, Iran, in 2009. The statistical design was factorial arrangement in complete randomized blocks with four replications. Four plant density (6, 8, 10 and 12 plants/m2) and four genotypes...

High planting density affects the morphology and productivity of many crop species. Our objectives were to examine the phenotypic and transcriptomic changes that occur during plant density stress in barley (Hordeum vulgare L.) and maize (Zea mays L.) seedlings. In maize and barley seedlings, density stress impacted several morphological traits. Gene expression profi les were examined in four ba...

the anatomical and epidermal characteristics, as well as the physiological response, of 'colombia' ecotype cape gooseberry plants treated or untreated with foliar applications of kaolin at 2 irrigation levels (well-irrigated plants vs. water-stressed plants) were evaluated. relative water content (rwc), stomatal density, and chlorophyll index were reduced under water stress. water stress increa...

Hassan Dehghanian Safar Nasrollahzadeh,

Objective: Field experiment was conducted in 2009 to investigate the effects of plant density and weed interference on morphological characteristics and yield of corn (Zea Mays, L.) at Research Station of University of Tabriz, Tabriz, Iran. Methods: The experiment was arranged as split plot based on randomized complete block design with three replications. Plant density (D1, D2, D3 and D4: 5, 7...
