ABSTRACT
The effect of varying potassium (0-control, 5, 10, 18 and 28 mM as potassium nitrate) and calcium (0-control, 5, 10, 18 and 28 mM as calcium nitrate) supply on growth of NaCl stressed (0-control, 100 and 150 mM) mature embryos of cucumber (Cucumis sativus L.) in vitro condition. NaCl caused decrease root (rooting percent, root number, root length and root fresh weight) and shoot (shoot length, shoot FW, leaf FW, whole plant FW) growth. Root/shoot length index and root/plant FW index was generally lower in the 100 and 150 mM NaCl concentrations than control (absence of NaCl). There was an increase in callus induction of NaCl treated cucumber embryos. Callus induction was decreased by K+and Ca2+ applications at both NaCl concentrations In general, root and shoot growth of cucumber embryos was improved by supplemental potassium (10 mM potassium nitrate) and calcium (20 mM calcium nitrate).
