Shang et Su ZHAO Yi-ning, LIU Yan-hong, ZHENG Peng-li, ZHOU Ming-qin HUBEI AGRICULTURAL SCIENCES    2024, 63 (5): 70-76.   DOI: 10.14088/j.cnki.issn0439-8114.2024.05.013 Abstract （261）      PDF （4693KB）（197）       Knowledge map    Save The seeds of Fraxinus hupehensis stored at normal temperature for 2 years were taken as the research object. Before the experiment, the radicle end covering tissue was removed to expose the radicle. Taking water as a control, after soaking the seeds with 150 mg/L gibberellin solution for 24 h, the physiological and biochemical indexes and the contents of endogenous hormones in seeds during germination were measured. The results showed that gibberellin treatment could enhance seed germination rate, with a germination rate of 24.67% after gibberellin treatment compared to 16.67% in the control group. During germination, gibberellin-treated seeds exhibited a trend of initially increasing and then decreasing in soluble sugar content. Soluble protein content showed a decreasing trend but remained significantly higher than the control group at all stages. Superoxide dismutase （SOD）, peroxidase （POD）, and catalase （CAT） activities showed an increasing trend on the whole. The content of endogenous jasmonic acid methyl ester （JA-Me） in seeds after gibberellin treatment was significantly lower than that in the control, which favored an increase in endogenous gibberellin （GA3） and zeatin riboside （ZR） content. The ratios of gibberellin to abscisic acid （GA3/ABA） and zeatin riboside to abscisic acid （ZR/ABA） were significantly positively correlated with the ratio of indole-3-acetic acid to abscisic acid （IAA/ABA） at 0.01 and 0.001 levels, respectively, and GA3/ABA was significantly positively correlated with ZR/ABA at 0.001 level. Gibberellin immersion significantly increased the germination rate of Fraxinus hupehensis seeds, and the seeds treated with gibberellin exhibited a stronger balance of protective enzyme activity system, delayed membrane damage, and the resistance was better. The lower levels of endogenous JA-Me and the higher levels of endogenous GA3 and ZR favored the initiation of seed germination and the release of dormancy. Reference | Related Articles | Metrics

The ratio of lesion area to total leaf area on the same leaf was used as the basis for disease severity grading, and the degree of black measles disease in grapes was predicted. 419 grapes disease images from the PlantVillage public database were accurately annotated and subdivided into three categories： background, leaves, and lesions, and data augmentation techniques were applied to increase sample diversity. Using BiSeNet as the benchmark model and introducing GhostNet as the backbone extraction network for context paths not only maintained a small number of model parameters, but also achieved a significant improvement in accuracy, meeting the needs of disease severity classification prediction. A cumulative atrous spatial pyramid pooling （CASPP） module was proposed to replace the single context embedding module in the BiSeNet model, in order to enhance the multi-scale context information extraction ability of the BiSeNet model and improve the segmentation accuracy of the model. After testing, the average Intersection over to Union of this research model in the test set was 94.11%. When predicting the degree of black measles disease in grapes, the accuracy reached 98.21%, which could accurately predict the degree of black measles disease in grapes.

Electronic nose analysis on scent of different varieties of rose flowers and buds WANG Shu, GUO Rui-qi, ZHAO Qiu-chen, WANG Ping, SUN Xin-ru, WANG Meng HUBEI AGRICULTURAL SCIENCES    2024, 63 (5): 77-83.   DOI: 10.14088/j.cnki.issn0439-8114.2024.05.014 Abstract （241）      PDF （5193KB）（97）       Knowledge map    Save With rose flowers and buds as test materials, the electronic nose technology was used to investigate the scent characteristics of different varieties of rose flowers and buds through multivariate statistical methods such as cluster analysis, Principal Component Analysis（PCA）and Orthogonal Partial Least-squares Discriminant Analysis（OPLS-DA）. The results showed that, 14 varieties of roses were divided into three categories, and the difference markers among the groups were W1W, W5S, and W2S, namely inorganic sulfides, nitrogen oxides, alcohol ether aldehydes and ketones. The intensity of the three difference markers was group 1 > group 2 > group 3, all of which had significant differences. The flower buds of 8 rose varieties were divided into three categories, and the difference markers among the groups were W5S and W1W, that was, nitrogen oxides and inorganic sulfides. The intensity of the two difference markers was group 1 > group 2 > group 3, all of which had significant differences. There were differences in the content of volatile components between rose flowers and buds. Most rose buds had higher content of volatile components than rose flowers, while a few rose buds had lower content of volatile components than rose flowers or had little difference in component contents. The main difference markers were W1W, W5S, W2S and W2W, that was, inorganic sulfides, nitrogen oxides, alcohol-ether aldehydes ketones, and organic sulfides. Electronic nose technology could quickly and effectively distinguish the difference of volatile components of different varieties of rose flowers and buds, and which could provide reference for rose aroma research and rose quality evaluation.

Ant species diversity of Dongchuan dry-hot-valley, Kunming City ZHU Hui-qin, XU Zheng-hui, QI Biao, LI Biao, CHEN Chao, GUO Ning-yan, QIAN Yi-shun HUBEI AGRICULTURAL SCIENCES    2024, 63 (5): 136-142.   DOI: 10.14088/j.cnki.issn0439-8114.2024.05.024 Abstract （205）      PDF （1659KB）（96）       Knowledge map    Save In order to clarify the ant diversity regularity in Dongchuan dry-hot-valley, Kunming City, and provide theoretical support for local vegetation restoration, the ant community was surveyed through the plot-sampling method. The results showed that 53 species belonging to 24 genera and 5 subfamilies of Formicidae were recognized in the 8 sample plots, of which Tetramorium wroughtonii （Forel） was the dominant species. Meanwhile, 7 common species （occupying 13.21% of the total species）, 11 relatively common species （occupying 20.75%）, 21 relatively rare species （occupying 39.62%） and 13 rare species （occupying 24.53%） were observed. Main indexe of ant communities was shown that species number was from 5 to 22 （average 12.8）, individual density was from 4.8 to 147.2 head/m2 （average 62.4 head/m2）, diversity index was from 1.049 2 to 2.048 0 （average 1.463 3）, evenness index was from 0.505 8 to 0.708 6 （average 0.595 4）, and dominant index was from 0.209 1 to 0.486 6 （average 0.347 2）. Similarity coefficients between ant communities from the 8 sample plots were 0.000 0~0.300 0, indicating that the similarity between the two different plots in the survey area was at the level of extremely dissimilar to moderately dissimilar. The ant species richness of Dongchuan dry-hot-valley was generally lower, and the combined effect of air temperature and humidity had important influence on vegetation, then influencing the main indexes of the ant community.
