We have been using a mutational approach to determine how plant-beneficial bacteria such as Enterobacter cloacae 501R3 obtain carbon and energy for colonization of subterranean portions of cucumber and other plants. Reduced carbon detected in cucumber root exudate consisted of 73.3 % amino acids, 22.2 % organic acids and 4.4 % carbohydrate. Ent. cloacae M2, a mini-Tn5 Km transposon mutant of st...

The great challenge of the agricultural sector is to produce more crop from less water, which can be achieved by increasing crop water productivity. The modernization of the irrigation systems offers a number of possibilities to expand the economic productivity of water and improve the virtual water status. The objective of the present study is to assess the global water productivity (GWP) with...

Abstract Negative pressure irrigation (NPI), which is a new subsurface technique, promotes vegetable yield, water productivity (WP), and nitrogen use efficiency (NUE). However, it not clear how NPI improves growth, especially in terms of supply characteristics uniformities soil nitrogen. In this study, cucumber pot experiment that had 0 kPa (PW1), –5 (PW2), –10 (PW3), –15kPa (PW4), traditional ...

irrigation scheduling means applying the right amount of water at the right time. in this research, thecurrent irrigation scheduling implemented in the mirza-kuchak-khan sugarcane agro-industry farmslocated in ahwaz was compared with the actual sugarcane crop water requirement using swapmodel. due to lack of field measured data, the swap model was calibrated and evaluated usinglandsat 7 etm+ im...

introduction: water scarcity is one of the primary problems in arid and semi-arid regions such as iran. in these regions, increasing water productivity in agriculture sector is inevitable. water productivity can be increased using the drip irrigation method and application of irrigation strategies such as deficit irrigation. potato is the major crop in dehgolan plain. researches have shown that...

Antioxidants and diets supplemented with foods high in oxygen radical absorbance capacity (ORAC) reverse age-related decreases in cerebellar beta-adrenergic receptor function. We examined whether this effect was related to the antioxidant capacity of the food supplement and whether an antioxidant-rich diet reduced the levels of proinflammatory cytokines in the cerebellum. Aged male Fischer 344 ...

With the development of science and technology, the problem about the quality safety traceability of agricultural products has already become the hot topic of researchers in various fields. Cucumber is one of the main vegetable crops in China. It is convenient for eating and contains various beneficial minerals. With the constant expansion of the planting areas, it plays a more and more importa...

Phenotypic plasticity in response to environmental variation occurs at all levels of organization and across temporal scales within plants. However, the magnitude and functional significance of plasticity is largely unexplored in perennial species. We measured the plasticity of leaf- and shoot-level physiological, morphological and developmental traits in nursery-grown Populus deltoides Bartr. ...

The effect of ultraviolet B (UV-B) radiation on the thermal sensitivity of cucumber (Cucumis sativus L.) was studied using UV-B-sensitive cv Poinsett 76 and UV-B-resistant cv Ashley grown under control and elevated (300 mW m-2) UV-B radiation levels. Using both cotyledon and leaf discs, the ability of the tissue to reduce triphenyl tetrazolium chloride (TTC) was determined after treatment at 50...

BACKGROUND Holothuria arenicola is the most important and abundant sea cucumber species in the Mediterranean Sea on the Egyptian coast. The present study aims to assess the anti-oxidative and anticholestatic effects of the sea cucumber Holothuria arenicola extract (HaE) in a model of bile duct ligation in male albino rats. METHODS Fifty four male Wistar albino rats were assigned into two main...
