Among fruit-fly species of the genus Drosophila there is remarkable variation in sperm length, with some species producing gigantic sperm (e.g., > 10 times total male body length). These flies are also unusual in that males of some species exhibit a prolonged adult nonreproductive phase. We document sperm length, body size, and sex-specific ages of reproductive maturity for 42 species of Drosop...
in order to achieve high quality seeds, producers must be able to estimate the accurate harvest maturity time seeds. the objective of this study was to investigate changes in seed quality during seed development and maturation in the two cultivars native of the sari and gorgan and two cultivars modified of the darab14 and yellowhite. a field experiment was conducted in during 2009 at gorgan uni...
Due to its indeterminate growth habit, maturation of cotton (Gossypium hirsutum L.) is affected by many environmental and cultural factors. An easy and reliable measure of its progression toward maturity that can be attained during crop development is needed for both production and research programs. As a cotton plant develops, first-position flowers progress toward the plant apex, and their re...
This research was designed and implemented to determine the effect of different irrigation regimes on the grain yield, dry matter, tiller number per unit area, degree of maturity, panicle harvest index, percentage of leaf rolling, day to 50% flowering, and the physiological maturity of rice genotypes, using a split plot randomized complete block design in two years (2014 and 2015). Four irrigat...
Transcriptional studies in relation to fruit ripening generally aim to identify the transcriptional states associated with physiological ripening stages and the transcriptional changes between stages within the ripening programme. In non-climacteric fruits such as grape, all ripening-related genes involved in this programme have not been identified, mainly due to the lack of mutants for compara...
