Association of carbon isotope discrimination with leaf gas exchange and water use efficiency in maize following soil amendment with superabsorbent hydrogel
... WUE at the yield level requires data on the actual crop water consumed during the season, which is difficult to measure. The weighing lysimeter and soil water balance equation are often used to estimate crop water ...

Changes in leaf water relations, gas exchange, growth and flowering quality in potted geranium plants irrigated with different water regimes
... INTRODUCTION The most important stress factor for seasonal plants in urban green areas is drought, especially for plants grown in containers. Plants have involved many physiological and morphological adaptations which ...
