Souhrn

Autor popisuje metodu stanovení vodního deficitu v terčíeích, vyseknutých z listů. Terčíky o průměru 8 mm se sytí položeny na polyetylenových kroužcích v otvorech v plotně z polyuretanové pěny, nasycené vodou (obr. 1, foto 1 a 2). Toto uspořádání umožňuje dokonalé nasycení pletiva během 3 hod. za minimální možnosti infiltrace.

Summary

The author describes a method for the determination of water deficit in disks punched out of leaves. The disks, 8 mm. in diameter, are placed on polyethylene rings and saturated in the apertures of a polyurethane foam plate which has been saturated with water (fig. 1, photo 1 and 2). This arrangement makes it possible for the tissue to be completely saturated in 3 hours with a minimum opportunity for infiltration.

Резюме

Автором описывается метод определения водного дефицита в дисках, высеченных из листьев. Диски диаметром 8 мм насьщаются после их установления на полиэтиленовые кольца в отверстиях в плите из полиуретановой пены, насыщенной водой (рис. 1, фот. 1 и 2). Данная схема позволяет полное насыщение ткани в течении 3 часов при минимальной возможности инфильтрации.
