The impact of the season on flowering time and the organization and morphogenesis of the reproductive structures are described in three tomato mutants: compound inflorescence (s), single flower truss (sft), and jointless (j), respectively, compared with their wild-type cultivars Ailsa Craig (AC), Platense (Pl), and Heinz (Hz). In all environmental conditions, the sft mutant flowered significant...

Flowering is one of the most influential events in the life history of a plant and one of the main determinants of reproductive investment and lifetime fitness. It is also a highly complex trait controlled by dozens of genes. Understanding the selective pressures influencing time to flowering, and being able to reliably predict how it will evolve in novel environments, are unsolved challenges f...

Pollen-mediated gene flow in space is well documented and isolation distances are recommended to ensure genetic purity of Brassica napus seed crops. Isolation in time could also contribute to gene flow management but has been little investigated. We assessed the effects of asynchronous and synchronous flowering on intraspecific B. napus gene flow by seeding adjacent plots of transgenic spring c...

This experiment was conducted, to study the effect of planting time and planting density on savory (Satureja sahendica Bornm.) in 2012 in Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran. The experiment was carried out in split plot in time in the form of a randomized complete block design with three replicates. The main plots were planting times in two levels ...

Organisms across the globe are experiencing shifts in phenological events as a result of ongoing climate change. Recently, variety novel methods have been applied order to fill gaps data set, which records often patchy temporal, spatial, and/or taxonomic resolution. Here, I tested whether changes flowering phenology could be detected through months stated 11 guides Swedish flora published over ...

Cytokinins may reflect soil water status and regulate rice (Oryza sativa L.) grain filling. This study investigated the changes in cytokinin levels in rice plants and their relations with grain filling under alternate wetting and drying irrigation. Two 'super' rice cultivars were field grown. Three irrigation regimes, alternate wetting and moderate soil drying (WMD), alternate wetting and sever...

PURPOSE To determine whether long-term brimonidine (BRI) treatment prevents the hyperglycemia-induced increase in vitreoretinal vascular endothelial growth factor (VEGF) expression and breakdown of the blood-retinal barrier (BRB) in streptozotocin (STZ)-induced diabetic rats. METHODS Brown Norway/Long-Evans rats were divided into three groups with similar distributions of blood glucose and bo...

A 10 yr old male with hypoxaemia, progressive infiltration on the chest radiograph and biopsy-proven desquamative interstitial pneumonia was treated with daily oral prednisolone for 6 months. Intravenous methylprednisolone pulses were concomitantly administered in doses averaging 10 mg x kg body weight(-1) on three consecutive days every 4-6 weeks. After 6 months improvement could be noted and ...
