Abstract
An experiment was conducted to determine the contents of K, Ca, P, Mg and Na, chlorophyll a, b and carotenoids in pineapple in vitro plantlets under salinity stress.
The cultivars N36, Morris and Sarawak were cultured on MS medium containing 0, 34, 68, 103, 137, 171, 205 or 240 mM NaCl for four weeks.
Increasing amounts of NaCl reduced the K, Ca, P and Mg content while Na increased in all pineapple cultivars.
Levels of chlorophylls and carotenoids generally showed no change or increased with increasing NaCl to 68 mM and then decreased as NaCl levels continued to increase.
Levels of chlorophylls and carotenoids were much higher in N36 than in the other two cultivars.
