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...

An experiment was conducted including 20 genotypes of maize during Kharif season 2020-21. All characters under study showed highly significant variation. High values genotypic and phenotypic coefficients variation were observed for the like anthesis silking interval, grain yield per plant, biological yield, number grains row, rows cob, harvest index ear height. Biological plant height, height h...

The present investigation was carried out to estimate genetic variability, correlation and path coefficient analysis for fifteen yield attributing traits of twenty maize genotypes in the kharif -2021 season at Field Experimentation Center, Department Genetics Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology Sciences, Uttar Pradesh Randomized block...

Field experiment was conducted during Rabi 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil in the experimental plot sandy loam texture, almost neutral reaction (pH 7.1), low organic carbon (0.36%), available N (171.48 kg/ha), P (15.2 kg/ ha) and K (232.5 kg/ha). arranged a Randomized Block Design with nine treatments each replicated three times based on one...

An Arabidopsis T-DNA insertion mutant that results in complete loss-of-function of the COBRA gene has been identified. The COBRA gene encodes a putative glycosylphosphatidylinositol (GPI)-anchored protein that modulates cellulose deposition and oriented cell expansion in roots. The loss-of-function mutant allele (named "cob-5") exhibits abnormal cell growth throughout the entire plant body and ...

The orientation of cell expansion is a process at the heart of plant morphogenesis. Cellulose microfibrils are the primary anisotropic material in the cell wall and thus are likely to be the main determinant of the orientation of cell expansion. COBRA (COB) has been identified previously as a potential regulator of cellulose biogenesis. In this study, characterization of a null allele, cob-4, e...

Identification of regulatory molecules that determine the extent and direction of expansion is necessary to understand how cell morphogenesis is controlled in plants. We recently identified COB (COBRA) as a key regulator of the orientation of cell expansion in the root. Analysis of the Arabidopsis genome sequence indicated that COB belongs to a multigene family consisting of 12 members, all pre...

Abstract The experiment carried out during season (2021-2022), in two locations first the village of “Abu maria” Tal Afar District (51 km) western Nineveh Governorate, and second location was Hamidat district “Badoush” (20 northwest aim studying response growth yield Cultivars Maze (Dragma Sengunto) for Slow Nitrogen Release fertilization (SNRF) at levels (0, 15, 30, 45 kg.ha −1 ) recommendatio...
