植物叶片细胞液浓度,是反映植物水分状况的重要生理指标之一。它能比较灵敏地反映外界条件的变化,目前已用来診断蔬菜作物、棉花、小麦、玉米、向日葵等作物对水分虧缺的程度。测定方法簡便,指示准确,能在田间直接診断植株水分状况。植物叶片细胞液浓度的测定,是由苏联学者洛鮑夫提出的。他根据的原理是细胞液浓度与蔗糖溶液浓度百分率相当,单位是用浓度百分率或者大气压表示。近几年我們在研究小麦和棉花植株水分 Plant cell cytosol concentration, is one of the important physiological indicators of plant water status. It can more sensitively reflect changes in external conditions, has now been used to diagnose vegetable crops, cotton, wheat, corn, sunflower and other crops on the extent of water deficit. The determination method is simple and accurate, which can directly diagnose the water status of plants in the field. The determination of the concentration of plant leaf cytosol was proposed by the Soviet scholar Lobauf. His rationale is that the concentration of the cytosol is comparable to that of the sucrose solution, and the unit is expressed as percent concentration or atmospheric pressure. In recent years we are studying the moisture of wheat and cotton plants
