high-density planting system is one of the effective methods for improving production and profitability of tree orchards. in this research, the effects of four planting densities (1904, 2666, 3137 and 4800 tree/ha) on annual shoot growth, tree yield, physicochemical properties of fruit and leaf mineral contents of apple (malus domestica borkh cv ‘granny smith’treegrafted on m26 clonal rootstock...

In other to study the effects of salicylic acid on reproductive characters of ‘Elberta’ Peach (Prunus persica L. Batsch) tree, an experiment was carried out based on randomized complete blocks design with four replications in commercial orchard, Kerman, Iran. The application of three concentrations of salicylic acid 0 (control), 1and 2 mM at swollen bud stage were used. Results showed that appl...

finding frequent patterns plays a key role in exploring association patterns, correlation, and many other interesting relationships that are applicable in tdb. several association rule mining algorithms such as apriori, fp-growth, and eclat have been proposed in the literature. fp-growth algorithm construct a tree structure from transaction database and recursively traverse this tree to extract...

Tree growth helps US forests take up 12% of the fossil fuels emitted in the USA (Woodbury et al. 2007), so predicting tree growth for future climates matters. Predicting future climates themselves is uncertain, but climate scientists probably have the most confidence in predictions for temperature. Temperatures are projected to rise by 0.2 °C in the next two decades, then by 1.5–3.5 °C at the e...

We introduce regenerative tree growth processes as consistent families of random trees with n labelled leaves, n ≥ 1, with a regenerative property at branch points. We establish necessary and sufficient conditions on the growth rules under which we can apply results by Haas and Miermont to establish self-similar random trees and residual mass processes as scaling limits. This framework includes...

Relationships between tree size and growth are sometimes assumed to show increasing with only until intermediate sizes reached, followed by a phase where rates decline further increases in size. However, this “rise-and-fall” pattern has been challenged studies suggesting continuously This study examined relationships diameter above-ground biomass (AGB) how such can differ depending on whether t...

abstract       1   most tree characteristics such as annual growth ring are influenced by climatic changes. dendroclimatology, a branch of dendrochronology science, studies the effects of climate parameters such as temperature and precipitation on the characteristics of annual growth ring. to carry out this research, 30 quercus persica coppice trees were selected in oak forest in khorramabad, l...
