ADJUSTMENT OF SOME ATRIPLEX SPECIES TO SALT AND HEAT STRESSES
Mohamed Abd El-Latif lbrahim Zaied;
Abstract
The present study aimed to asses the impact of heat, salt
and their interaction on growth, photosynthesis,. carbohydrate, nutrient element and protein contents as well as protein patterns in two halophytes Atriplex nummu/aria and A. halimus .
The study included two steps; the first one is intended to
determine the maximum tolerance of salinity and temperature levels for each species.
Seeds of each species were divided into eight groups, four
were planted in plastic pots ( 20 seeds each ), containing pure sand and irrigated with distilled water for one month, then with one-half strength nutrient solution for another two months. At the begining of the third month, three groups were subjected to salt application; I 00, 300 or 600 mM NaCl and one was left
as control ( at 20 ± 2°C ). The other four groups of seeds, three
• only were incubated for 12 hours under different temperature
pretreatments; 25, 35 and 45°C and one was left as control, then transferred to be planted and to complete their growth for three months as mentioned above
