Communities of Arbuscular Mycorrhizal Fungi in Pyrus pyrifolia var. culta (Japanese pear) and an Understory Herbaceous Plant Plantago asiatica
We investigated communities of arbuscular mycorrhizal fungi (AMF) in the fine roots of Pyrus pyrifolia var. culta, and Plantago asiatica to consider the relationship between orchard trees and herbaceous plants in AMF symbioses. The AMF communities were analyzed on the basis of the partial fungal DNA sequences of the nuclear small subunit ribosomal RNA gene (SSU rDNA), which were amplified using...
متن کاملCommunities of Arbuscular Mycorrhizal Fungi in the Roots of Pyrus pyrifolia var. culta (Japanese Pear) in Orchards with Variable Amounts of Soil-Available Phosphorus
We examined the colonization rate and communities of arbuscular mycorrhizal fungi (AMF) in the roots of Pyrus pyrifolia var. culta (Japanese pear) in orchards to investigate the effect of phosphorus (P) fertilization on AMF. Soil cores containing the roots of Japanese pear were collected from 13 orchards in Tottori Prefecture, Japan. Soil-available P in the examined orchards was 75.7 to 1,200 m...
متن کاملRadical Scavenging Activity in Fruit Extracts
Phytochemicals in plants, vegetables and fruits have been reported to prevent oxidative stress related diseases, such as cancer, cardiovascular disease, cataracts, brain and immune-system dysfunction and inflammation. Many plant phenolic flavonoids have been shown to have antioxidant activity. In our study, the polyphenolic content and the radical scavenging activity of a number of Thai fruit e...
متن کاملIdentification of QTLs controlling harvest time and fruit skin color in Japanese pear (Pyrus pyrifolia Nakai)
Using an F1 population from a cross between Japanese pear (Pyrus pyrifolia Nakai) cultivars 'Akiakari' and 'Taihaku', we performed quantitative trait locus (QTL) analysis of seven fruit traits (harvest time, fruit skin color, flesh firmness, fruit weight, acid content, total soluble solids content, and preharvest fruit drop). The constructed simple sequence repeat-based genetic linkage map of '...
متن کاملVariation of Phenolics and Antioxidant Activity between Peel and Pulp Parts of Pear (pyrus Communis L.) Fruit
The aim of present study was to appraise the antioxidant activity and phenolic contents in peel and pulp parts from two locally harvested verities of pear. The extraction yield of antioxidant components obtained with 80% methanol (80:20 methanol-water v/v) was found to be 14.30-17.50% for peel and 11.50-13.00 g/100 g for pulp on dry weight basis. The total phenolic contents and total flavoniod ...
