Classification of Korla fragrant pears using NIR hyperspectral imaging analysis

SPIE Proceedings, 2012
Korla fragrant pears are small oval pears characterized by light green skin, crisp texture, and a pleasant perfume for which they are named. Anatomically, the calyx of a fragrant pear may be either persistent or deciduous; the deciduouscalyx fruits are considered more desirable due to taste and texture attributes.

Investigations into the production of volatile compounds in Korla fragrant pears (Pyrus sinkiangensis Yu)

Food Chemistry, 2020
The composition of volatile compounds in Korla fragrant pears was determined using headspace solid-phase microextraction followed by a gas chromatography-mass spectrometry analysis using fruits at 30, 90, and 150 days after bloom. Hexanal, (E)-2-hexenal, 1-hexanol, (E)-2-hexen-1-ol, (Z)-3-hexen-1-ol, and hexyl acetate were identified as the major ...

[Effects of nitrogen application level on photosynthate distribution of Korla fragrant pear trees].

Ying yong sheng tai xue bao = The journal of applied ecology, 2021
Using 13C pulsed labeling technique, we examined the biomass and carbon accumulation of different organs as well as the distribution characteristics of 13C assimilate of 6-year-old Korla fragrant pear trees under three nitrogen application levels, i.e., 150, 300, and 450 kg N·hm-2 (marked as N1, N2, and N3, respectively).

The Model of the Korla Fragrant Pear Mature Based on Effective Accumulated Temperature

Applied Mechanics and Materials, 2014
In order to investigate the mature law of Korla fragrant pear with mathematics method, Korla pears in Aksu area be taken as the study object, and the fruit hardness and soluble solid content (SSC) be selected as the research index. The data of the two indices in the mature process are analyzed with Excel, SigmaPlot and Matlab.

Cloning and expression analysis of an MYB gene associated with calyx persistence in Korla fragrant pear

Plant Cell Reports, 2014
We isolated an MYB-like gene from Korla fragrant pear using differential display RT-PCR. Expression of this gene in flowers appears to be correlated with calyx persistence. Korla fragrant pear (Pyrus brestschneideri Rehd) is an economically important pear cultivar in China. A persistent calyx results in the deformation of the fruit.

CGS-YOLOv11s: target detection algorithm for Korla fragrant pears in multiple natural environments

Engineering Research Express
Abstract The color of Korla fragrant pears often closely resembles that of the surrounding leaves. Furthermore, mutual occlusion among fruits and foliage increases detection difficulty, making them harder to identify than common fruits under natural environments.
