Abstract

The stability of some morphological and biometric characteristics of ‘Nonpareil’ almond [Prunus dulcis (Mill.) D.A. Webb, syn. P. amygdalus Batsch.] pollen was evaluated to determine its usefulness in distinguishing among different cultivars. The influence of rootstock, irrigation, geographical location, and year on pollen grain size and pollen ultrastructural microsculpture was followed. No parameter was influenced by irrigation or rootstock, but grain size and pore diameter class distribution were significantly different for the years and localities studied.

changes of leaf L:W ratio in response not only to ADT, but to day/night temperatures clearly show the diurnal thermoregulation of plant morphology. The smaller leaf L:W ratio at lower temperatures is in agreement to that observed by Lin and Lee (1988

strategy for urban landscape development. In a saline environment, morphological and physiological processes in plants are disturbed, leading to an inhibition of growth ( Alvarez and Sanchez-Blanco 2014 ). High concentrations of salts in soil or water

advancement. A large variation in tree architecture and other morphological characters was found in different fruit species, for example, apple ( Lespinasse, 1977 ), pear ( Sansavini and Musacchi, 1994 ), and peach ( Scorza, 1984 ). Implementation of these

studies have catalogued the morphological diversity because the crop is hard to establish and maintain ( Tangarife et al., 2009 ). However, molecular studies with easily extracted DNA have been common, with various types of genetic markers showing that
