It is evident the masses ofovule is composed of the following morphological parts, meristimatic cells represent a stage of undeveloped ovulesnucleus, integuments, embryo sac, funiculus’s and that leads to reduction in initial, final fruit set and yield.micropyles (Figs 9 and 10). However, different types ofabnormal ovaries were consistently formed in the control CONCLUSIONflowers. Histological features of abnormal development insections of ovaries from flowers of the control trees are It can be concluded from results of the present studysections with reduced number of developed carpel’s, that 30 cm root pruning at bud break treatmentsome had only 4 or 3 carpel’s (abnormal or malformed significantly improved flowering, fruiting and fruit qualityovary), carpels without ovules or absence carpels (Figs 8a of ‘Le Conte’ pear trees, consequently it is recommendedand b). A mass of meristimatic cells making differentiated to be effectively applied under the same conditions.
