| Abstract:
The influence of the irrigation rates on the development of water saturation deficit (WSD) was studied and expressive gradients were found in the plant. Pepper plants grown at the low level of soil moisture received a xeromorphic character and the youngest vegetative organs had a distinct preference in water supply. The relatively high WSD and its expressive gradient between the upper and medium canopies caused various changes in the metabolism, followed consequently by various depressions reflected in the total plant productivity. The plants grown at higher irrigation rates showed lower WSD values and small differences in its gradient proved the steady water balance connected with more intensive productive plant activity. Various adaptability to differentiated irrigation rates was revealed by estimating the cultivar. | |
