Rachises of grape (Vitis vinifera L.) clusters that appeared healthy or displayed symptoms of the ripening disorders berry shrivel (BS) or bunch-stem necrosis (BSN) were treated with the cellular viability stain fluorescein diacetate and examined by confocal microscopy. Clusters with BS and BSN symptoms experienced a decrease of cell viability throughout the rachis, and their berries contained ...

In this special issue on the Evo-Devo of amniote integuments, Alibardi has discussed the adaptation of the integument to the land. Here we will discuss the adaptation to the sky. We first review a series of fossil discoveries representing intermediate forms of feathers or feather-like appendages from dinosaurs and Mesozoic birds from the Jehol Biota of China. We then discuss the molecular and d...

With the development of open science and technological innovation, using sharing data molecular biology techniques in study taxonomy systematics have become a crucial component plants, which undoubtedly helps us discover more hidden outliers or deal with difficult taxa. In this paper, we take Dennstaedtia smithii as an example, based on database, virtual herbarium plant photo bank, to clarify t...

A field experiment was executed under sub-tropical conditions during the period from April 2020 to March 2021 observe effects of bulb sizes on flower and yield tuberose cv. single. The consisted three namely, a small-sized (1.0-1.5 cm in diameter); medium-sized (1.6-2.5 diameter) large sized (2.6-3.0 diameter). Results disclosed that plant height, number leaves plant-1, leaf length breadth, lat...

Two new species of Tetradiplosis inducing galls on Prosopis caldenia are described from Argentina: Tetradiplosis panghitruz Martínez n. sp. and Tetradiplosis rayen Martínez n. sp. Tetradiplosispanghitruz induces multilocular galls on vegetative stems, whereas T. rayen induces unilocular galls containing multiple larvae on the rachis of the developing inflorescences. The adult male, female, pupa...
