Grafting has been utilized to develop horticultural crops increase plant vigor, yield potential, and tolerance various environmental stresses. employs selected rootstocks of the same species or near relatives. Moreover, dwarfing is a desirable feature for intensive cultivation efficient orchard management. However, information on regulatory mechanisms rootstock-induced vigor control remains unc...

Rhizobium radiobacter is a significant causal agent that ranks among the top ten bacteria of molecular plant pathology in world, has largest range hosts pathogenic bacteria, and limits production leads to economic losses agriculture. The distinctive feature from other Ti plasmid, extrachromosomal structure present all virulent types. In this study, virulence five R. isolates (1A, 1B, 2A, 2B RK ...

Surveys were conducted in the major apple growing regions of New York state to determine the incidence of borers infesting burrknots on clonal apple rootstocks. Dogwood borer, Synanthedon scitula (Harris), was generally prevalent throughout the state, but American plum borer, Euzophera semifuneralis (Walker), was limited to western New York apple orchards near infested stone fruit trees. Insect...

Grape root borer, Vitacea polistiformis (Harris), is an oligophagous and potentially destructive pest of grape in commercial vineyards throughout much of the eastern United States. Larvae feed on vine roots, although little is known about their below-ground interactions with host plants. The behavioral response of groups of grape root borer neonates to stimuli from host and nonhost roots was ev...

Apple chlorotic leaf spot virus (ACLSV) is the type member of the Trichovirus genus, the family Flexiviridae (Martelli et al., 1994; Adams et al., 2004) and is known to infect most pome and stone fruit tree species, including apple, peach, pear, plum, almond, cherry and apricot (Lister, 1970; Németh, 1986). ACLSV has a worldwide distribution and induces a large variety of symptoms in sensitive ...

Shoots of apple rootstocks raised in vitro were transferred to various rooting media to study the effect of different factors on root initiation and development. Various concentrations of indole-3-butyric acid (IBA) initiated rooting but maximum rooting percentage was found with 2.0 and 2.5 mg l(-1) of IBA in M7 and with 1.0 mg l(-1) of IBA in MM106. The drawback was that the roots were thick, ...
