Riparian phreatophytes in hyperarid areas face selection pressure from limiting groundwater availability and high transpiration demand. We examined whole-plant water use hydraulic traits Populus euphratica Tamarix ramosissima seedlings to understand how they adapt variations. These species coexist the Tarim River floodplain of western China. Measurements were performed on 3-year-old grown lysim...
How genome divergence eventually leads to speciation is a topic of prime evolutionary interest. Genomic islands of elevated divergence are frequently reported between diverging lineages, and their size is expected to increase with time and gene flow under the speciation-with-gene-flow model. However, such islands can also result from divergent sorting of ancient polymorphisms, recent ecological...
During the last decades the importance of the genus Populus increased because the poplar genome has been sequenced and molecular tools for basic research have become available. Poplar species occur in different habitats and harbor large genetic variation, which can be exploited for economic applications and for increasing our knowledge on the basic molecular mechanisms of the woody life style. ...
اندوخته شدن کربن در زیتوده گیاهی ساده ترین و به لحاظ اقتصادی عملیترین راهکار برای کاهش دی اکسید کربن اتمسفری است. تحقیق حاضر در مورد چهار گونه صنوبر کاشتهشده در ایستگاه تحقیقات صنوبر بلداجی واقع در استان چهارمحال و بختیاری انجام شده است. این چهار گونه شامل دو گونه بومی استان یعنی populus alba و p. nigra و دو هیبرید p. alba × p. euphratica و p. euphratica × p. alba هستند. نمونهبرداری از درختا...
