abstract to optimal use of available water, irrigation scheduling is important to over scarcity of water resources in arid and semi-arid area. in this research to estimate of maximum allowable deficit (or: management allowed depletion) and irrigation scheduling of fodder mays based on canopy-air temperature difference, a field study was conducted in agricultural faculty of karaj. the lower limi...

The term vitamin E refers to a group of eight lipophilic compounds known as tocochromanols. The tocochromanols are divided into two groups, that is, tocopherols and tocotrienols, with four forms each, namely α-, β-, γ-, and δ-. In order to explore the temporal biosynthesis of tocochromanols in olive (Olea europaea cv. 'Koroneiki') fruit during on-tree development and ripening over successive gr...

High temperature is one of the most important environmental factors that affect the successful cultivation of apple (Malus × domestica Borkh). The expression of genes related with anthocyanin synthesis and sugar accumulation by high temperature treatment was investigated in the fruits of “Fuji” apple at different developmental stages in different temperature conditions through realtime PCR. In ...

this study performed to evaluate genetic diversity of some wild and domesticated (unknown foreign cultivars) blackberries in sanru collection based on morphological traits. results showed high diversity for flowering, ripening time and fruit juice. wild genotypes showed significant differences in leaf, flower, thorn number, fruits and seed fresh weight compared to domesticated cultivars. based ...

The rate at which tomato fruits ripe was investigated via the biosynthesis of lycopene in two tomato varieties under the conditions of field and ambient temperature ripening. Results showed that the biosynthesis of lycopene follows a first-order kinetics in both varieties with calculated rate constants of 1.2×10-2 and 1.4×10-2 d-1 for Ibadan local and Roma types respectively under the field rip...

partitioning of photoassimilates between the sinks is one of the most important physiological processes related to the yield of crops which are affected by drought stress. therefore, the effect of drought stress in flowering and grain filling stages, on the percentage partitioning of photoassimilates among different organs was studied in 14 rapeseed cultivars in a split plot experiment based on...
