It is studied reactions crack and the basic cells the bottom and top surface of a leafat on action of heats (27°, 35°, 40°, 45°) variation of water-security of leaves of types of sort Juglans at constant humidity of air (45 %) and at exception adjustable influences of root system. It is shown, that the least water-keeping capacity leaves J. manshurica, J. siboldiana, J. cordiformis, that comparably big fraction of freely water in fabrics of a leaf possess; the greatest water-keeping capacity leaves J. regia, J. nigra. Cracks J. regia J. nigra possess, J. cinerea possess high stability to temperature, conductivity crack significantly decreases to 40°С, crack have expressed of a leaf a layer on a surface. Crack J. manshurica, J. siboldiana, J. cordiformis are characterized the big conductivity at action 35°C, distinctive feature cracks - absence expressed of a leaf a layer on surfaces, their acting position above a surface of a leaf. The basic cells the bottom and top surface of a leafat loss of a moisture reduce the area, the factor of tortuosity anticlinal wall increases. The increase become thick a cellular wall, expressiveness of a leaf a layer on surfaces of the basic cells increases stability of cells of a leaf to lose water. Basic cells J. manshurica differ the least stability to water deficiency (especially the basic cells top surface of a leaf).
