Reducing levels of fruit set is often desirable in many European pear (Pyrus communis L.) cultivars. With a negative linear relationship between crop load and size, management early the season minimises wastage tree carbohydrate resources provides maximum benefits terms size quality. There are several tools available for managing including hand thinning, chemical photosynthetic inhibition throu...

گلابی pyrus communis l. از مهم‎ترین میوه‎های دانه‎دار در جهان است. علاوه بر این، وجود سایر گونه‎های متعلق به جنس pyrus نظیر گلابی ژاپنی p. pyrifolia, syn. p. serotina سبب گستردگی و تنوع بیشتر این میوه شده است. در کشور ایران، نقاطی نظیر استان‎های ساحلی دریای خزر به‎ویژه استان گیلان، استان‎های غربی، نظیر استان کردستان و استان‎های واقع در رشته کوه‎های البرز و زاگرس، مراکز تنوع قابل توجه برای گون? ...

The nutritional value of the peeled and unpeeled fruit (peel plus flesh tissues) was studied using four peach (Prunus persica L.; Red Heaven, Maria Blanca, Big Top, Queen Giant), two pear (Pyrus communis Santa Maria, Pyrus pyrifolia N.; Nashi), three apple (Malus domestica Borkh.; Gala, Granny Smith, Chief) cultivars. Based on principal components analysis (PCA) models, there a clear differenti...

Genetic maps are essential tools for pear genetics and genomics research. In this study, we first constructed an integrated simple sequence repeat (SSR) and single nucleotide polymorphism (SNP)-based consensus genetic map for pear based on common SSR markers between nine published maps. A total of 5,085 markers, including 1,232 SSRs and 3,853 SNPs, were localized on a consensus map spanning 3,2...

This project work focuses on the comparison of engineering properties Pyrus communis under solar and air-drying method. Green samples wood were dried simultaneously in both kiln open air for 15 days. The daily moisture content reduction (%MC) drying conditions observed recorded. Mechanical tests (shear strength, compressive hardness tensile strength) conducted. results showed that air-dried woo...
