The hyperspectral imaging technology is used to detect early-maturing pear’s effective acidity nondestructively, and effective prediction model is established. 145 pears’ hyperspectral images are obtained in the wavelength range of 400nm-1000nm. Total 145 pears are separated into the calibration set (77 samples) and prediction set (68 samples). Early-maturing pear’s effective acidity partial le...

BACKGROUND Some European pear varieties treated with 1-methylcyclopropene (1-MCP) often remain 'evergreen', meaning that their ripening process is blocked and does not resume after removal from cold storage. In this work this was confirmed also to be the case in 'Conference' pears. To reverse the blockage of ripening 1-MCP treatments combined with external exogenous ethylene were tested. RESU...

L-ascorbic acid (L-AA) concentration changes during the development of cv. Conference pears and the influence of postharvest handlings (gas condition, cooling rate, cooling duration) on L-AA breakdown were studied. L-AA concentration fluctuates in young fruits, remains stable during fruit maturation, and starts to decline 1 week before commercial harvest. The most rapid decrease in L-AA concent...

Color is an important agronomic trait of pears, and the anthocyanin content of fruit is immensely significant for pear coloring. In this study, an anthocyanin-activating R2R3-MYB transcription factor gene, PyMYB10.1, was isolated from fruits of red sand pear (Pyrus pyrifolia cv. Aoguan). Alignments of the nucleotide and amino acid sequences suggested that PyMYB10.1 was involved in anthocyanin r...

To better understand the cold-induced regulation of scald-like disorders in pears and specific roles played by ethylene ?-farnesene, three pear cultivars with different patterns production chilling requirement were used this study. Fruit treated 1-MCP (ethylene inhibitor) Lovastatin (?-farnesene stored at -0.5 °C 90 % RH during 6 months. Changes targeted metabolites, enzymes genes monitored per...

marrow material taken during therapy, it will be possible to explore if these second cancers emerge before the initiation of thiopurine therapy.4 Second, if de Boer et al are correct in their hypothesis, we would expect a reduced level of DNA-6TGN incorporation in the HGPRT-deficient t-AML/MDS clones compared with the normal bone marrow cells when such cases occur during thiopurine therapy. Usi...
