primary bud necrosis in grapevine is a physiological disorder observed in the compound buds. this study was conducted to investigate the anatomical changes in cv. askari grapevine in winter dormant buds. bud samples were taken from askari grapevine at sisakht vineyards, south-western of iran. compound buds were dissected and assessed under a binocular microscope at 10-40x magnification and a di...

Optimal control in a multistage physiologically structured insect population model. Abstract: We present an age-and stage-structured population model to study some methods of control of one of the most important grapevine pests, the European grapevine moth. We consider control by insecticides that reduce either the proportion of surviving eggs, larvae or both, as well as chemicals that cause ma...

Growing grapevine (Vitis vinifera) is a key contribution to the economy of many countries. Tools provided by genomics and bioinformatics did help researchers in obtaining biological knowledge about the different cultivars. Several genetic markers for common diseases were identified. Recently, the impact of microbiome has been proved to be of fundamental importance both in humans and in plants f...

The Greek grammarian and lexicographer, Hesychius of Alexandria (5th–6th c. CE) included a Pamphylian gloss: βουρικυπάρισσος ἡ ἄμπελος. Περγαῖοι in his dictionary rare dialectal words. Based on microphilological lexical analysis, I suggest that the text should be read as follows: βουρί˙κυπάρισσος ἢ (“bourí: cypress or grapevine. Citizens Perge”). gloss question represents two different borrowin...

black meristematic fungi are cosmopolitan and able to adapt to extreme fluctuations of ultraviolet radiation, temperature, and moisture and grow in exposed habitats such as stone surfaces. in a survey on fungi associated with fruit rots, leaf spots, canker, gummosis, dieback and trunk diseases of grapevine and walnut trees in kurdistan province (iran), some black meristematic fungal isolates re...
