| Abstract | ||||
| The Morphological and physiological responses of 6 olive cultivars seedlings namely; “Agezee”, “Koroneiki”, “Picual”, “Nebal”, “Manzanillo” and “Coratina” to three levels of calcium carbonate in soil (9.4%, 22% and 38.1% CaCO3) and two irrigation levels which were 60% and 30% available water “A.W” were studied during two successive seasons, 2012 and 2013.The present study was achieved on one-year old seedlings grown in black plastic bags under saran green house conditions at the experimental farm of the Fac. of Agric. at Demo, Fayoum, Egypt. A negative relationship was found between CaCO3% in soil and/or deficit irrigation on growth Parameters of seedlings (plant height, leaf area, total shoot length/plant, dry weight/plant, root length density), total chlorophyll (mg/g fresh weight) and total carbohydrate %. There were great differences among cultivars in their response to CaCO3% in soil and drought. The cvs. that were most tolerant are “Nebal” followed by “Agezee” but “Coratina”, “Koroneiki” and “Manzanillo” were most susceptible; while “Picual” was intermediate tolerant. 53 | ||||
