Abstract

This research was done in order to study and determine the quantity of the useful mineral components in leaves and finding out leaf parameters such as leaf area , wet and dry weight , dampness percentage and the leaf area proportional to its mass in usual conditions for pistcia mutica trees in the forest area of mah Parviz pass in Yasuj on a slope altitude of 1850–2600 meters. In this research 30 PISTACIA MUTICAl trees were selected and 4 leaves from each base in four geographical directions were selected and totally there were 120 leaves. sampling was entirely random in four geographical directions. The samples were selected from different heights the lower, ceteral and upper part of the crown of PISTACIA MUTICA trees. Meanwhile the SPECIAL LEAF AREA and the mineral components of the leaves were determind in the laboratory, too. the results obtained analysing the leaves show that the samples from pistacia mutica in the dry material were (92.04%), Ca(1.47%), P(0.12%), K(0.99%), Na(0.005%), Mg (0.74%), CU (2.48%) and N(0.43%).The results obtained from studying the SPECIAL LEAF AREA and changes show that the ratio of the dry and wet weight in different geographical directions and different parts of the trees crown don’t show glaring differences, but the SPECIAL LEAF AREA shows a noticeable difference in different parts of the tree crown and different directions in a case that in the north an south directions in a dry state the SPECIAL LEAF AREA at the upper part of the tree crown in order are between 68.9 to 79.1 and 66.6 to 76.6 square millimeters and in a wet state 33.3 to 38.5 and 33.8 to 39.8 square millimeters and in the east and west directions in dry weight state are respectively 55.1 to 63.6 and 62.4 to 68.6 square millimeters and in wet weight state the differences are between 33.3 to 34.3 and 30.2 to 37.2 square millimeters.
