Under normal environmental conditions, many plants synthesize cyanogenic glycosides, which are able to release hydrogen cyanide upon hydrolysis. Each year, there are frequent livestock and occasional human victims of cyanogenic plants consumption. The present work aims to determine the hydrocyanic acid content in different samples of cyanogenic plants, selected from the Tunisian flora, and in t...

Global warming, through affecting the dormancy progression of temperate fruit trees, has a profound impact on bud break, flowering and fruiting performance. This may lead to economic losses in production genus Prunus sp., which cultivation is common regions worldwide, producing edible drupes such as almond, apricot, cherry, plum, peach nectarines. To overcome climate change-related tree disorde...

A comprehensive model of stem and root diameter variation was developed. The stem (or root) was represented using two coaxial cylinders corresponding with the mature xylem and the extensible tissues. The extensible tissues were assumed to behave as a single cell separated from the mature xylem by a virtual membrane. The mature xylem and the extensible tissues are able to dilate with temperature...

The aim of this study was to trace the Fe uptake pathway in leaves of Prunus rootstock (GF 677; Prunus dulcis × Prunus persica) plants treated with foliar Fe compounds using the Perls blue method, which detects labile Fe pools. Young expanded leaves of Fe-deficient plants grown in nutrient solution were treated with Fe-compounds using a brush. Iron compounds used were the ferrous salt FeSO4, th...

Physiological factors have effects on most forest parameters such as forest classification so that understanding knowledge about this subject is important to manage forests. The forests of Sorkhake-sanjabi village with area of 1645 ha located in Eslam Abad city, Kermanshah province, Iran were selected. 23 sample plots with rectangular shape (40m*50m) were selected and the species, origin of spe...

BACKGROUND Growing evidence shows the potential of nutritional interventions to treat obesity but most investigations have utilized non-digestible carbohydrates only. Peach and plum contain high amounts of polyphenols, compounds with demonstrated anti-obesity effects. The underlying process of successfully treating obesity using polyphenols may involve an alteration of the intestinal microbiota...

The North American plums are a closely related group that are not easily circumscribed, have overlapping morphologies, and are known to hybridize. We previously showed that the North American plums are a closely related, monophyletic group of taxa with little to no cpDNA sequence divergence between taxa. In that study, we came to the unanticipated conclusion that relationships inferred among th...
