The study was conducted to determine the effects of nitrogen fertilizing systems and harvest frequency on levels of hard-seedness and hard-seed softening trend in M. scutellata var. Robinson. The study was carried out at Agricultural Research Farm of University of Tehran in Karaj during 2006. The experimental design was a randomized complete block with a split-split plot arrangement with four r...
Leaf-level morphological and physiological responses of mature, winter-deciduous, shade-tolerant Acer saccharum Marsh. trees to gap formation caused by selection harvest were studied experimentally over a 2-year period. We found no evidence for either physiological stress or positive acclimation following gap creation during the 1-2-week post-harvest period. Rather, lower-canopy leaves showed g...
the yield and quality features of raisin are affected by various factors especially har-vest date and dipping solutions. combinations of different harvest date (four harvest dates) and post harvest alkaline emulsion (three alkaline solutions) were tested in vitis vi-nifera l. cv ‘paycamy’ green raisin production in kashmar, khorasan province of iran. such raisin quantitative and qualitative cha...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

The activity of ionically bound peroxidases from an asparagus spear increased from 5-24 h post-harvest. Isoelectric focusing showed that the post-harvest increase of the total peroxidase activity was due to the increase of several distinct isoperoxidases. Concomitantly, a decrease in the activity of two anionic peroxidases was observed. Peroxidases with pI 5.9, 6.4 and 9.2 were detected only at...
Post-harvest diseases are one of the main causes of reducing the supply of fresh garden products. The occurrence of post-harvest diseases can affect the quality and limit the shelf life of fresh horticultural products. Currently, strict ordinances apply to import agricultural products. One of these regulations is the minimum residual pesticide residue in the fresh food sector. On the other hand...
