We assessed changes in ultrastructure, membrane lipid peroxidation and antioxidant systems for cucumbner seedlings subjected to low temperature stress (day/night temperature of 8 oC /5 oC) that had been either pre-treated with 10% PEG for 2 days or not. We found extensive cell structure damage in the non-treated seedlings, whereas the seedlings pretreated with PEG to simulate drought remain...

Abstract: The occurrence of damage and empty space inside the seed can directly affect germination. aim this study was to evaluate relationship between or cowpea seeds physiological potential. In study, seven lots cultivar ‘BRS Guariba’ were subjected X-ray test identify by tissue deterioration, mechanical damage, insects malformed and, later, germination test. percentage embryonic area coat de...

Underplanting tree seedlings in areas where natural regeneration is limited may offer a tool by which desired overstory composition can be maintained or restored in forests. However, invasive plant species and ungulate browsing may limit the effectiveness of underplanting, and in-turn, the successful restoration of forest ecosystems. Individually, the invasive shrub Lonicera maackii and browsin...

An alternative in vitro protocol for embryo induction directly from intact living seedlings of Phalaenopsis aphrodite subspecies formosana was established in this study. Without the supplementation of plant growth regulators (PGRs), no embryos were obtained from all the seedlings when cultured on the solid medium. In contrast, embryos formed from the seedlings on the 2-layer medium and the 2-st...

Seedling is an indispensable stage in plant cycle life, and seedling survival is important during natural vegetation restoration, especially on the Loess Plateau. In 2007, we selected 4 plots of Artemisia scoparia communities (ASC) and 4 plots of Artemisia gmelinii + Artemisia giraldii communities (AGC), examined seedling richness, diversity during the rainy season, and examined mature vegetati...

Wormwood sagebrush (Artemisia sieberi Besser) is one of the most widely distributed shrub species in Iran and Turkistan steppes, its establishment on dry lands has generally been proven difficult because of low seedling vigor, inability to compete with herbaceous species, poor seed quality, and altered edaphic conditions. In order to evaluation of planting methods and seedling establishment, se...

the present study evaluate the histopathologic findings and clinical indications in hysterectomized patients based on sonographic assessments. this study population consisted of all patients who were referred to the pathology ward of imam reza educational and treatment center (kermanshah, iran) during march 2006 to may 2012. the samples were stained with hematoxylin-eosin after fixation in form...

objective: hashimoto encephalopathy (he) is known as a steroid-responsive encephalopathy associated with autoimmune thyroiditis or nonvascular inflammation-related autoimmune meningoencephalitis. the average age of onset of he is approximately 50 years; and it is more common in women. the onset of he may be acute or subacute. the course of most he cases is relapsing and remitting, which is simi...
