To date, the effects of nanoparticles on woody plants remain unaddressed. This study reveals some of the physiological and biochemical effects of SiO2 nanoparticles on wild pear seedlings. The seedlings were irrigated with different concentrations of nano silica (0, 10, 100, 500 and 1000 mg/l) for 14 days. Nanoparticle adsorption and absorption, biomass allocation, gas exchange, relative water ...

The effects of grafting on the morphology, physiology, and aerenchyma balsam pear aboveground under waterlogging stress were studied using a two-factor randomized block design. At 8 16 days, degree reduction grafted was lower than those self-rooted pear, although height leaf number pears remarkably reduced stress. Compared with considerably decreased malondialdehyde content leaves but substanti...

The white grub Laniifera cyclades Druce of prickly pear cactus or nopal is a pest that limits the commercial production of Opuntia . The gregarious larvae perforate the cladodes devouring the inner part, thereby forming large galleries until reaching the central axis of the plant; during their movement through the inner part of the cactus, the larvae make orifices to the exterior to expel their...

This article provides a review of Pear Deck which allows teachers to create interactive slide presentations. In this article, we first provide an overview Decks’ features and some background information about tool. Then, discuss its technological as well pedagogical features. Next, evaluate the teacher fit in terms theoretical underpinning tool how it can support student learning. We underline ...

The endogenous and environmental regulation of red colour development in blushed and fully red pears is reviewed. Colour development in pears has an underlying developmental component. Generally, highest anthocyanin concentrations are attained in immature pears and colour tends to fade towards harvest. This is contrary to most other crop species where maximum pigmentation and colour are attaine...
