to determine the best planting date and irrigation schedule in a cotton field (gossypium hirsutum var.varamin) in garmsar region an experiment was conducted in 2011. the experimental design was splitplot based on randomized complete block with three replications. three irrigation termination dates (2011sep 11th, 2011 sep 21st and 2011 oct 2nd) arranged in main plots as main factor and three pla...

this study was carried out to investigate flower yield and yield components in iranian rosa damascena using 20 genotypes, collected from different regions of iran and grown in drylands and deserts research station of kashan, iran, using a randomized complete block design with three replications in 2007-2008. flower yield per plant, number of flowers per plant, plant height, leaf length, width, ...

Flowering time in rice (Oryza sativa L.) is determined primarily by daylength (photoperiod), and natural variation in flowering time is due to quantitative trait loci involved in photoperiodic flowering. To date, genetic analysis of natural variants in rice flowering time has resulted in the positional cloning of at least 12 quantitative trait genes (QTGs), including our recently cloned QTGs, H...

†Background and Aims Ageing effects may be due to dysfunction leading to decreasing reproduction and survival with age. In plants, however, other (physiological) causes, associated with size for example, may also play a role. Iteroparous plants with genetically variable life spans can be helpful in unravelling these two aspects of changes associated with growing older. †Methods In a long-term e...
