“…C. aucheri, as well as previously studied species native to the Gulf, have reported to contain high level of carbohydrates content (nitrogen-free extract), and the content was found to increase during dry periods (Morsy et al 2008;Shaltout et al 2008;Gad et al 2012). However, when compared to other lignocellulosic biomasses, such as prairie grasses or corn stover (Cybulska et al 2012), the glucan fraction of halophytes was found to be relatively low (< 20 g/100gDM) and the total extractives fraction relatively high (> 30 g/100gDM), as it contained the extractable ash washed out from the salty plants.…”

Extensive comparative characterization was performed to explore halophytes native to the Persian (Arabian) Gulf. Ten species collected from the Western region of Abu Dhabi, United Arab Emirates (UAE) were analyzed for their lignocellulosic components as well as for ash and extractives content. It was found that the species significantly differ in the content of carbohydrates, lignin, total ash-free extractives and total ash. The total ash content was found to negatively influence the content of carbohydrates. Based on the characteristics, it is concluded that Cornulaca aucheri is the most attractive as a source of carbohydrates, and Tetraena (Zygophyllum) qatarensis has the potential to produce the highest yield of the extractives fraction.

Coastal Pinus thunbergii (Japanese black pine) forests in the northern Shandong Peninsula of China recently experienced widespread natural regeneration failure. This study identifies critical factors that affect natural regeneration of P. thunbergii. Seeds from trees of various ages (13-32 years) were used to investigate the effects of age and burial depth in sand on germination and seedling establishment. Results show that seed density in 2-5 cm soil decreased with increased distance from the shoreline. Sand burial decreased seed germination but did not affect the relative growth rate of seedlings at depths from 0.5 to 3 cm. Germination, leaf mass ratio, and relative growth rates were higher with seedlings originating from older trees, all of which enhanced seedling resistance to sand burial. Tree age and seed burial were found to be determining factors for natural regeneration of the coastal P. thunbergii forest. Silvicultural treatments that promote quality of seed sources and mitigation of sand burial can be used in the future to improve the regeneration of these coastal forests.Keywords: coastal forest, seed germination, biomass allocation, relative growth rate, seedling establishment RÉSUMÉ Les forêts côtières de Pinus thunbergii (pin noir du Japon) situées dans la péninsule septentrionale de du Shandong ont affiché été victimes dernièrementrécemment d'importants échecs de la régénération naturelle.

Paronychia argentea is a wild medicinal herbaceous herb that contains many secondary metabolites. It grows wild in Jordan under harsh high salinity soil conditions. This study was conducted to investigate the effect of salinity stress on growth, biochemical responses, and ion uptake of in vitro Paronychia argentea micro plants. Our results revealed a clear reduction in all growth parameters in response to an increase in salinity level used (0, 25, 50, 100, 200 mM). When the growth medium was supplemented with 200 mM NaCl; the fresh and dry weights were reduced by 40% compared with the control treatment. Moreover, micro plant uptake of phosphorus calcium and potassium ions decreased with increasing salinity levels. The Mg++ content was increased by 10% at the 25 mM level of NaCl compared with control, while it declined by 20% at 200 mM of NaCl. On the other hand, Na+ uptake increased with increasing salinity levels and reached a maximum value of (18328 ppm/D. W) at 200 mM NaCl. Moreover, proline content increased in response to salinity level to record maximum value (80.8 µmole/g) at 200 mM NaCl compared to (30.4 µmol/g) obtained in the control. Quercetins content in P. argentea micro plants was increased by 1.7-fold in concentration in response to salinity at 50 mM of NaCl, while an about 7-fold increase in the concentration of isorhamnetin content was obtained due to salinity at 100 mM.
