Mineral nutrient composition in leaf and root tissues of fifteen polyembryonic mango genotypes, grown under varying levels of salinity

Mango (Mangifera indica L.) is a salt sensitive crop and its cultivation in affected area declining day by day. There need to find out the rootstocks sustain under saline conditions which can be used for commercial of superior cultivars through grafting. To achieve this, present study was carried understand tolerance nature fifteen polyembryonic mango rootstock seedlings (EC-95862, Bappakkai, Vellaikolamban, Nekkare, Turpentine, Muvandan, Kurukkan, Kensington, Olour, Manipur, Deorakhio, Vattam, Mylepelian, Sabre Kitchener) were exposed 0 mM, 25 50 mM 100 concentration NaCl+CaCl2 (1:1) salt. The outcome this revealed that there reduction K+, Ca++, Mg++, Fe++ Zn++ while content Cu++ Mn++ both leaf root tissues found increase with gradual from mM. overall results salinity stress caused alterations mineral nutrient composition genotypes. Among genotypes Olour Bappakkai respond better maintaining status higher level salinity.
