خانواده گز یک خانواده بنسبت کوچک از 3 تا 5 جنس و حدود 100 گونه است. جنس tamarix بزرگ ترین جنس این خانواده است. جنس گز بدلیل داشتن گل های ریز و صفات ریخت شناسی متنوع یکی از مشکل ترین جنس های شاخه نهاندانگان است. در این پژوهش مطالعه تشریحی و نموی ساختار زایشی نر و مقایسه ی آن در دو گونه ی t. ramosissima و t. korolkowii انجام گرفت. نتایج نشان می دهد که فرایند های تمایز بافتی در دو گونه یکسان می با...
Many species have been found to be capable of foliar water uptake, but little research has focused on this in desert plants. Tamarix ramosissima was investigated to determine whether its leaves can directly absorb water from high humidity atmosphere and, if they can, to understand the magnitude and importance of foliar water uptake. Various techniques were adopted to demonstrate foliar water up...
Cousinia Cass. is one of the widespread genera Asteraceae family. There a large number ofpharmacological activity studies on this genus and it has not yet been examined phytochemically in detail. Pseudo taraxasterol (ψ-taraxasterol) pentacyclic triterpene with different pharmacological such as antinociceptive, anti-inflammatory. In report, we aimed to evaluate ψ-taraxasterolcontent, which isola...
Clarifying the water uptake patterns and competition among riparian plants under different ecological conveyance conditions is crucial for stability of ecosystem in arid areas. Here, we have utilized Bayesian isotope mixing model to quantify plant sources two typical (Tamarix ramosissima Phragmites australis) along Manas River Xinjiang, Northwest China. The relationship between these evaluated ...
Blackbrush (Coleogyne ramosissima Torr.) is the dominant shrub on three million hectares across transition zone between western North American warm and cold deserts. This paper presents a study of blackbrush population structure at stand level sixteen sites species range. New stand-level information then integrated with what already known about ecology to explore consequences several unusual fe...
A Bowen ratio energy balance was conducted over a Tamarix ramosissima (saltcedar) stand growing in a riparian corridor along the Virgin River in southern Nevada. Measurements in two separate years were compared and contrasted on the basis of changes in growing conditions. In 1994, a drought year, record high temperatures, dry winds, and a falling water table caused partial wilt of outer smaller...
