Abstract: (960 Views)
In order to investigate the effect of yellow and blue nets and their installation time on the characteristics of figs, a factorial experiment was carried out in the form of a randomized complete block design with three factors in three replications on rainfed fig. By assessing many of the leaf and fruit features of figs, the results showed that there is a slight difference between the two times of the net installation. It also confirmed the superiority of trees with shading than without a covering net in terms of leaf properties (increased leaf width and reduced margin necrosis) and fruit quality (increase in size). In addition, colored nets were able to compensate for the lack of fruit water during ripening by maintaining the relative water content of the leaf and the optimal reduction of the leaf’s temperature in rainy conditions. The use of shaded nets in Sabz and Siah fig trees prolonged the storage life of their fresh fruits. There was a slight difference between the two-colored nets, the blue net was better than the yellow net, with an increase in some favorable characteristics, especially the rate of photosynthesis, fresh fruit storage life, titratable fruit acids up to 11.5 µmol m−2 s−1 ,14.1 days and 0.24, respectively. Installing a blue net on the fig tree in mid-May increased leaf photosynthesis. The use of shading improves the quality of the economic performance of figs and increases the economic efficiency of fig orchards. The use of the blue net had an economic advantage compared to the yellow net.
