ذخیره سازی در فراسرد یا c°196- روشی جدید و بسیار کارآمد در نگهداری بلندمدت ژرم‎پلاسم گونه‎های گیاهیست. با استفاده از روش فراسرد می توان بذر، اندام رویشی، سلول و دانه گرده گیاهان را برای بلندمدت نگهداری و در صورت بروز هر گونه تهدید یا خطر انقراض نسبت به بازگشت و احیاء گونه اقدام کرد. در شرایط فراسرد، اغلب فعالیت‎های متابولیکی سلول تقریباً متوقف و طول مدت نگهداری بطور چشمگیری افزایش می یابد. بذر گ...

In the study were presented data for comparison of antibacterial activities between long time stored acacia (Robinia pseudoacacia L.), multifloral and oak (Quercus spp.) honeydew honeys towards Staphylococcus aureus (ATCC 9144). The results showed that the antibacterial activity of oak honeydew and multifloral honeys was much higher in comparison with acacia honeys with the lowest antibacterial...

Mycorrhizal technology was applied for reclamation of saline wasteland of Indian Thar Desert. For this purpose an exotic tree species Acacia colie an endemic legume of Australia was selected. Studies revealed increased biomass production and nutrient uptake of Acacia collie by native AM fungi. Different AM fungi showed their variation towards response to this tree species. However, AM fungi res...

The vegetative performance of four nectarine tree scion/rootstock combinations, with varying growth capacities, were analysed in the Spring after the canopy:root ratio was dramatically reduced by severe pruning in the dormant season. We anticipated that severe pruning and reduction of the shoot:root ratio would mitigate known root water supply limitations related to the various rootstocks and d...

We studied relationships between diurnal patterns of stem water potential (PsiSTEM) and stem extension growth of the same scion cultivar growing on three rootstocks with differing size-controlling potentials. The peach trees (Prunus persica (L.) Batsch) used in this field experiment consisted of an early-maturing freestone cultivar, 'Flavorcrest,' grafted onto three different rootstocks: Nemagu...

Present experiments were conducted to determine the possibility of artificial culture with various sawdust of P. gilvus. The pH value was 6.0 of oak sawdust, 6.5 of mulberry sawdust, 6.6 of elm sawdust, 6.3 of acacia sawdust and 6.1 of apple tree sawdust. Mycelial density on elm sawdust and acacia sawdust were lower than those of oak sawdust, and apple sawdust. Weight of fresh fruiting body sho...

به منظور شناسایی گونه­های جنس pseudocercospora نمونه برداری از مناطق مختلف استان­های شمالی کشور در طول تابستان و پاییز سال 1389 انجام شد. علاوه بر این نمونه­های موجود در مجموعه قارچ­های وزارت جهاد کشاورزی واقع در مؤسسه تحقیقات گیاه­پزشکی کشور نیز مورد بازبینی قرار گرفتند. گونه­های pseudocercospora atromarginalis (روی solanum nigrum)، p. cruenta (روی vigna sinensis)، p. griseola (روی phaseolus v...

Three closely related oRUulosic q l i c latex 6ims were prepared employing acacia pulp fibers, cellulose whiskers and daclocellulose balls and their respective strength properties were determined. Wulose whisker reinforced composites had &md stl.ength properties compGired to the acacia pulp and nanoball composites. APM analysis indicated that the d u b w h i s h &or& composite exhibited d e c r...

By applying a fed-batch strategy, production of Penicillium occitanis mannanases could be almost doubled as compared to a batch cultivation on acacia seeds (76 versus 41 U/mL). Also, a 10-fold increase of enzyme activities was observed from shake flask fermentation to the fed-batch fermentation. These production levels were 3-fold higher than those obtained on coconut meal. The high mannanase p...

Obligate Acacia ant plants house mutualistic ants as a defense mechanism and provide them with extrafloral nectar (EFN). Ant/plant mutualisms are widespread, but little is known about the biochemical basis of their species specificity. Despite its importance in these and other plant/animal interactions, little attention has been paid to the control of the chemical composition of nectar. We foun...
