A new three-locus model for rootstock-induced dwarfing in apple revealed by genetic mapping of root bark percentage
Rootstock-induced dwarfing of apple scions revolutionized global apple production during the twentieth century, leading to the development of modern intensive orchards. A high root bark percentage (the percentage of the whole root area constituted by root cortex) has previously been associated with rootstock-induced dwarfing in apple. In this study, the root bark percentage was measured in a fu...
متن کاملClarifying the effects of dwarfing rootstock on vegetative and reproductive growth during tree development: a study on apple trees.
BACKGROUND AND AIMS Despite the widespread use of dwarfing rootstocks in the fruit-tree industry, their impact on tree architectural development and possible role in the within-tree balance between growth and flowering are still poorly understood, in particular during the early years of growth. The present study addressed this question in apple trees, through a detailed analysis of shoot popula...
متن کاملIdentification of DNA Markers Linked to Blooming Time in Almond
In this study flowering time and other important morphologic traits were evaluated during two years in F1 almond progenies of seventy two seedlings from cross between the intermediate flowering Italian cultivar ‘Tuono’ and the extra-late blooming Iranian cultivar ‘Shahrood-12’. A modified-bulk segregant analysis in combination with the application of the 140 RAPD primers, 87 nuclear ...
متن کاملAdvances in Apple Culture Worldwide1
Over the last 60 years, planting densities for apple have increased as improved management systems have been developed. Dwarfing rootstocks have been the key to the dramatic changes in tree size, spacing and early production. The Malling series of dwarfing rootstocks (M.9 and M.26) have been the most important dwarfing rootstocks in the world but are poorly adapted in some areas of the world an...
متن کاملBlends of Agar/Galactomannan for Marubakaido Apple Rootstock Shoot Proliferation
Galactomannans (GMs) extracted from seeds of a native Brazilian specie designated Cassia fastuosa (cassia) and from Cyamopsis tetragonolobus (guar gum – a commercial GM) were mixed with agar, in the proportion of 3/3 g.L (w/w), and used as a gelling agent in Marubakaido apple rootstock (Malus prunifolia Borkh) micropropagation. The rheological measurements of the gels showed a good interaction ...
