We investigated the effects of different concentrations (0, 1, 2 and 4 mM) of putrescine on chilling injury, fruit quality, ethylene production rate, fatty acid composition and the antioxidant system of cold-stored kiwifruit (Actinidia chinensis Planch. var. chinensis 'Hongyang'). We achieved a significant decrease in ethylene production, maintained fruit quality and alleviated chilling injury ...

The theory has recently been put forward by Renwick (1972a) that anencephalus and spina bifida are caused by exposure early in pregnancy to potatoes which are affected by blight or are imperfect for other reasons. In support of this, a temporal correlation was claimed to exist between the severity of blight and the frequency of anencephalus, largely because of a strong correlation between the a...

A kivi (Actinidia chinensis Planch. var. deliciosa (A. Chev.) A. két kivadult egyedét mutattuk ki Pécsett, városi környezetben. Mindkét tő téglafalak lábazatánál, ereszcsatornák kifolyóinál lévő repedésekben, zöldséges árudák bejáratának közelében fordult elő a város különböző pontjain. gyakori visszavágás ellenére 2019-ben elsőként megtalált példány minden évben erőteljes vegetatív hajtásokat ...

Austral summer frosts in the Andean highlands are ubiquitous throughout the crop cycle, causing yield losses. In spite of the existing warming trend, climate change models forecast high variability, including freezing temperatures. As the potato center of origin, the region has a rich biodiversity which includes a set of frost resistant genotypes. Four contrasting potato genotypes--representing...

the use of nitrogen in nutrient media is essential for growth and helps identify highly productive media for potato (solanum tuberosum l.) micropropagation and adventitious shoot formation. three potato cultivars (agria, marfona and savalan cultivars) were examined for their growth response with medium containing four different levels of kno3 (1, 1.25, 1.5 and 1.75 times as much 1.9 g l-1) and ...

This study was carried out to evaluate the effects of salicylic acid in Marfona potato cultivar (Solanum tuberosum L.) for reducing the pathogenesis of Rizoctonia solani in potato tubers under greenhouse conditions. The pots sterilized soils had been infected by R. solani (21B1 strain) two weeks before transplanting the potato plantlets. The seedlings were treated with 0 (control), 0.1, 0.2, 0....
