| Popis: | Influence of 2.75 to 11 moles sucrose as an exogenous osmoprotectant on salt stressed (7.8-9.1 and 18.2 ms/cm) and temperature stressed (42.36C) Azolla (A. filiculoides Lam.) was studied. Results showed that enriching salt stressed (9.1 ms/cm) Azolla by 5.5 moles sucrose significantly increased survival percent (S%) and freshness percent (F%), in comparison with control treatment in which no sucrose was used. Enriching Azolla media by 2.75, 5.5 and 8.25 moles sucrose in optimum growth condition (24.18C and 0.65 mS/cm), had no significant effects on growth doubling time (D.T), S% and F% in comparison with control. Enriching Azolla media by 11 moles sucrose in optimum growth condition decreased significantly the S% and F%, in comparison with control plots. Enriching Azolla media by 5.5 moles sucrose, in all salinity levels (0.65, 7.8, 9.1 and 18.25 ms/cm), and air temperatures (24.18 and 42.36C), non increased S% and F% but not significantly and decreased D.T.A positive correlation was o..... |
