In order to evaluate the effect of plant growth regulators on sex determination and yield, an experiment was conducted by spraying different hormonal combinations on medicinal pumpkin. Experimental treatments were included different concentrations of NAA (25, 75, 100, 125 mg/l), paclobutrazol (50, 100, 200 and 300 mg/l) and combination of growth regulators (NAA 25 mg/l + PBZ 50 mg/l), (NAA 75 m...

in order to evaluation of squash (cucurbita pepo) seed yield per fruit and its relations with other characteristics of fruit include: length, diameter, length: diameter ratio (fruit shape), flesh thickness, thousand seed weight and fruit weight, an experiment was conducted using 24 accessions of squash as a randomized complete-block design with three replications. morphological traits were eval...

this experiment was conducted to determine gene action for different traits of chickpea including days to 50% flowering, days to maturity, plant height, 100-seeds weight, number of pods per plant and seed yield. five genotypes including arman, hashem, ilc588, iccv2 and ilc3279 were selected and crossed with each other. four generations of each cross along with parents were evaluated in a random...

The exotic vine Vincetoxicum rossicum (Kleopow) Barbar. (Asclepiadaceae) is a major natural-areas pest throughout the Great Lakes Basin. Colonization of new areas by this herbaceous perennial occurs by comose wind-dispersed seeds. Previous experiments suggested a trade-off between seed dispersability and seed quality: smaller seeds dispersed farther but were less likely to emerge and seedlings ...

this experiment contained four vetch lines (vicia panonica ) that conducted in two locations (faruj and bojnourd) in 2005-2006 in rcbd design with four replications under dryland conditions. analysis of variance indicated that there were significant differences among lines in different locations about all traits, except 100-seed weight. the interaction of genotype×location was significant on al...

The effect of potash biofertilizer and chemical fertilizer was studied on quantitative and qualitative traits of periwinkle in a factorial experiment based on a Randomized Complete Design with three replications, 48 experimental units, and two factors: (1) different methods of potash bio-fertilizer application at four levels of control (B0), seed inoculation (B1), root inoculation (B2) and seed...

Double inoculation of soybean with Bean pod mottle virus (BPMV), a member of the Genus Comovirus, Family Comoviridae, isolates V-S98-1 and V-S98-15, together with Soybean mosaic virus (SMV) a member of the Genus Potyvirus, Family Potyviridae) isolates 2K-38, S98-51 and S98-52, was compared to single inoculation with each of the isolates, on Hutcheson, Hutcheson Roundup Ready® (RR BC3) and Hutch...

Seed size and seed weight are major quality attributes and important determinants of yield that have been strongly selected for during crop domestication. Limited information is available about the genetic control and genes associated with seed size and weight in sorghum. This study identified sorghum orthologs of genes with proven effects on seed size and weight in other plant species and sear...

A field experiment was conducted at the `Research Farm` of Regional Seed Production Office of Lal Teer Seed Limited, Dinajpur, Bangladesh during November 2008 to April 2009. The study was conducted to investigate the effect of bulb size and planting spacing on seed production of cultivar Taherpuri onion. Three bulb sizes [small (5±2g), medium (10±2g), and large (15±2g)] and four planting spacin...
