Water content, thickness of linden leaf blades in relation to spider mite populations in urban conditions. Progress in Plant Protection, 37: 65-67.
Abstract
Specific leaf area (SLA), dry matter content in the leaves of linden (Tilia) trees growing in traffic-polluted areas of Warsaw, Poland, were studied. The leaf samples were taken from the trees during two growing seasons (1995 and 1996). The relationship between leaf morphology and water content and the number of Eotetranychus tiliarium was studied. It was found that the leaves of linden trees growing in the most polluted area of Warsaw (B-1) during the dry summer of 1995 (in contrast to the wet summer of 1996) had a higher dry matter content (lower water content). They had the greatest area and were the thickest (the lowest value of SLA). The leaves taken from the most polluted sites were attractive to E. tiliarium.
