abstract in order to study of relationship between timing and duration of phenological events and grain yield of wheat plants, an experiment was performed at moghan college of agriculture and natural resources-university of mohaghegh ardabili research farm during 2010-2011. the plant materials (81 wheat cultivars) were evaluated using a simple lattice design with two replications under irrigate...

The main types of reproductive system structure, development and functions in cephalopods are described from personal observations and use of the literature. There is one type in males and three in females which are order specific. These have provided a basis for examining possible evolutionary trends in reproductive system development and in reproductive strategies within coleoid cephalopods a...

Accumulation of bioactive compounds, during developmental stages of Graptopetalum paraguayense E. Walther, was investigated between 30 and 90days as a function of physiological maturity. Three distinct phases were defined: immature phase (30days), intermediate developmental phase (30-60days), and maturation phase (60-90days). Gallic acid and quercetin, antioxidative bioactive compounds, were id...

Abstract In plants, a fascinating set of post-fertilization events result in the development dispersal unit known as seed. During maturation phase, seeds accumulate storage reserves and acquire desiccation tolerance, followed by an increase seed vigour during drying. Physiological (or mass) maturity may be attributed to stage when maximum dry matter accumulation has occurred, marking end seed-f...

seven maize inbred lines were crossed in a complete diallel cross design at the seed and plant improvement institute, karaj, iran, during the 2006 growing season. the parents and 42 f1 hybrids were grown in the research field of islamic azad university of firoozabad, firoozabad, iran, using a randomized complete block design (rcbd) with three replications, during the 2007 growing season. the ha...
