the present study was done to investigate the correlation between biochemical changes of grafted tree fruits and rootstock fruits in gorgan university of agricultural science and natural resources in 2012-2013. for this purpose, the antioxidant activity and the total content of phenol and  flavonoid on four rootstocks such as yuzu (citrus junos), shelmahalleh (citrus sinensis var. shel mahalleh...

the type of training system and application of calcium spray have considerable effects on storability of fruits. in this study, the effects of calcium chloride spray (0, 0.75, 1.5 and 3 g.l-1) in three times during 2, 4 and 6 weeks before harvest time on apple (malus domestica) fruits cvs. ‘gala’ and ‘delbarestival’, which trained in three different training systems (v shape, hightech and cordo...

Covariance functions and variograms play a fundamental role in exploratory analysis and statistical modelling of spatial and spatio-temporal datasets. In this paper, we construct a new class of spatial covariance functions using the Fourier transform of some higher-order kernels. Moreover, we extend this class of spatial covariance functions to the spatio-temporal setting using the idea used in...

pistachio has a special ranking among iranian agricultural products. iran is known as the largest producer and exporter of pistachio in the world. agricultural products are imposed under different thermal treatments during storage and processing. designing all these processes requires thermal parameters of the products such as specific heat capacity. regarding the importance of pistachio proces...

Tests were conducted to determine whether the lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), selects rough rice (Oryza sativa L. (Poales: Poaceae)) kernels with cracked hulls for reproduction when these kernels are mixed with intact kernels. Differing amounts of kernels with cracked hulls (0, 5, 10, and 20%) of the varieties Francis and Wells were mixed with intact ke...

most of the citrus fruits, especially in north of iran are stored in common storages. this experimen in oder to persevere appearance and internal fruit quality were conducted in the citrus research station at 1392, britex-ti wax, storage wax, polyethlene bag (individual fruit), polyethlene bag (pair fruits) were used alone and with combination with methyl salicylate (mesa) vs. control (without ...
