2010/11/24
The S-phenotypes (self-incompatibility phenotypes) of Japanese pear (Pyrus pyrifolia Nakai) ‘Chikusui’, ‘Shinseiki’, ‘Seigyoku’ and ‘Housui’ determined their S-genotypes by molecular markers were veri...
Influences of Applied Nitrogen Amount in Autumn on Cold Hardiness and Lipid Content of Japanese Pear
global warming meteorological disasters nitrogen unsaturated lipid
2010/11/24
We investigated the influence of the amount of applied nitrogen on cold hardiness and lipid content of Japanese pear ‘Nijisseiki’ and ‘Hosui’. ‘Hosui’ was more sensitive to excessive nitrogen applicat...

2009/7/8
The effects of 0, 25 or 100 mM NaCl treatments on ion uptake and gas exchange of the Japanese pear ‘Akibae’ grown on the rootstocks P. betulaefolia, P. calleryana and P. pyrifolia were investigated. T...
Characterization of Fruit-Type Sucrose Synthase Gene Promoters Isolated from Tomato and Japanese Pear
promoter sucrose synthase
2010/3/4
We isolated the 5’ upstream promoter regions of the fruit-type sucrose synthase (SS) gene from tomato and Japanese pear by inverse PCR. The 5’ region of the tomato SS gene (TOMSSF) contained an intron...
