Abstract :
The impact of harvest time and the type of quantitative and qualitative indicators covering some applesseed (Red delicious) Naser Kazemi1- Mohammad Gholami Pareshkoohi2 - Davood Mohammad Zamani3 1- MA, in of Mechanics of agricultural machinery, Department of Agronomy, University Takestav ,Islamic Azad University,Gazvin, Iran 2- Assistant Professor, in of Mechanics of agricultural machinery, Department of Agronomy, University Takestav ,Islamic Azad University,Gazvin, Iran 3- Assistant Professor, in of Mechanics of agricultural machinery, Department of Agronomy, University Takestav ,Islamic Azad University,Gazvin, Iran Abstract The tests in 1394 and completely randomized in a factorial design. Fruits in two stages and were taken to the morgue at an interval of 15 days and then packed into 3 categories with 3 repetitions were divided. And the quantitative and qualitative characteristics more mass, soluble solids, dry matter percentage changes, weight changes box, change the mass of dry matter were measured immediately after harvest. The results showed that more mass gradually during storage, box weight and soluble solids and dry matter content increased crime reduction. The soluble solids gradually break with fruit ripening and complex polysaccharides into simpler substances and sometimes also increased due to decreased respiration and decomposition of sugars. Fruits wrapped in paper Graph smaller reduction in the weight of the box (first), TSS (second stage) as well as a lower increase in dry matter (second stage) showed. Reducing dissolved solids (first stage) and an increase in mass of dry matter (first phase) in the fruits wrapped in the guise of graph paper + oil + straw compared to the coverage graph and graph paper straw was lower. Graph paper + straw wrapped fruit to fruit wrapped in paper graph Vgraf oil + straw reduce Drjrm less than (first phase), more crime (second period), box weight (second period), and a lower increase in the percentage of female dry (first phase) and the mass of dry matter (second stage) showed. According to the results, through the coverage studied, covering graph paper + straw highest performance in maintaining fruit quality apple varieties Red Delicious and Red Delicious varieties most suitable time to harvest apples picked in the second round (20 October).
