Tamarix is one kind of shrub which is widespread species in sand and saline land in arid and semi-arid regions. Tamarix has been paid more attentions for its unique physiological and ecological features, and important socioeconomic effects. In order to study the biomass and growth status of Tamarix, we need to measure the morphological parameters (e.g. height, perimeter of canopy). However, the...
مطالعه ای از جنس گز (tamarix) در پاکستان شامل اصول نامگذاری، کلید شناسایی، شرح واحد های رده بندی، لیست ایستگاه های جمع آوری و نکات انتقادی دیگری ارائه می گردد. این مقاله بر اساس مطالعه مقدار قابل توجهی از نمونه های زنده و نمونه های هرباریوم تهیه گردیده بطوریکه نگارنده کلیه نمونه های تیپ واحدهای رده بندی مشروحه را مشاهده و از نزدیک مورد مطالعه قرار داده است. بطوریکه جمعاً 25 گونه گز در پاکستان شن...
We examined the impact climate change (CC) will have on the availability of climatically suitable habitat for three native and one exotic riparian species. Due to its increasing prevalence in arid regions throughout the western US, we predicted that an exotic species, Tamarix, would have the greatest increase in suitable habitat relative to native counterparts under CC. We used an ecological ni...

Tamarix ramosissima has bi-seasonal flowering and fruit-setting characteristics. This study compared the morphology and germination characteristics of seeds from Tamarix ramosissima plants during the spring flowering period and the summer flowering period. The results are as follows: there is no significant difference in morphology, such as size and thousand-seed weight, between seeds from diff...

Fungal strains naturally occurring on the wood and leaves of the salt-excreting desert tree Tamarix were isolated and characterized for their ability to produce cellulose- and starch-degrading enzymes. Of the 100 isolates, six fungal species were identified by ITS1 sequence analysis. No significant differences were observed among taxa isolated from wood samples of different Tamarix species, whi...
Patterns of woody-plant mortality have been linked to global-scale environmental changes, such as extreme drought, heat stress, more frequent and intense fires, and episodic outbreaks of insects and pathogens. Although many studies have focussed on survival and mortality in response to specific physiological stresses, little attention has been paid to the role of genetic heritability of traits ...
The paleartic tamarix leafhopper, Opsius stactogalus Fieber (Hemiptera: Cicadellidae), can reduce the growth of tamarisk due to the aggregate feeding imposed by their populations. The species was mentioned for Argentina in Metcalf's catalogue (1967) without locality or region reference, and the contributions on Cicadellidae published by many authors after Metcalf omitted this distributional dat...
Antioxidant activity of a selection of commonly occurring wild plants growing in Beni-Sueif governorate, Upper Egypt, has been tested. The plants selected are Tamarix nilotica, Ambrosia maritima, Zygophyllum coccenium, Conyza dioscoridis, Chenopodium ambrosioides, and Calotropis procera. The in vitro antioxidant assays used in this study were 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scaven...
