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.
