Effect Of Exogenously Applied Spermidine On Growth And Physiology Of Citrus Rootstock Troyer Citrange Under Saline Conditions, Muhammad Akbar Anjum
Turkish Journal of Agriculture and Forestry
The aim of this study was to assess the effects of spermidine (Spd) on ameliorating adverse effects of salinity in Troyer citrange seedlings. For this purpose, 6-month-old, uniform-sized seedlings of Troyer citrange were transplanted to plastic containers containing Hoagland nutrient solution. Addition of 75 mM NaCl into the nutrient solution reduced the plant growth, leaf chlorophyll content, chlorophyll fluorescence yield (Fv/Fm), net photosynthetic rate, respiration rate, and total Spd, N, and Ca^{2+} + Mg^{2+} contents of the leaves. It increased the leaf proline, total putrescine (Put), total spermine (Spm), Na^+, and Cl^- contents of the leaves. Addition of Spd (0.1 …

The present study was undertaken to contribute to the continuous search for efficient in vitro protocols for the micropropagation of olive trees, with special focus on the Oueslati cultivar. It investigates the main factors involved in the micropropagation process, namely medium composition, growth regulators, rooting, and acclimatization conditions. It demonstrates that under particular conditions, the Oueslati cultivar displays a high capacity to proliferate. During the multiplication phase, the multiplication medium, which is a modification of Rugini medium with zeatin (1 and 2 mg L^{-1}), yielded the highest multiplication rates, with an average of more than 9. Furthermore, almost 91% of …
