Citrus Huanglongbing (HLB) is nowadays one of the most fatal citrus diseases worldwide. Once the citrus tree is infected by the HLB disease, the biochemistry of the phloem region in midribs would change. In order to investigate the carbohydrate changes in phloem region of citrus midrib, the semi-quantification models were established to predict the...
Citrus Huanglongbing (HLB) has posed a great challenge to the citrus production. Timely removal of HLB infected trees was considered as one of the most effective strategies for citrus orchard management. Therefore, rapid detection of HLB disease is urgently needed. The study was aimed to propose an effective method for HLB disease detection by deve...
Salt stress is one of the abiotic factors that causes adverse effects in plants and there is an urgent need to detect salt stress in plants as early as possible. Multicolor fluorescence imaging, as a powerful tool in plant phenotyping, can provide information about primary and secondary metabolism in plants to detect the responses of the plants exp...
Deep learning is known as a promising multifunctional tool for processing images and other big data. By assimilating large amounts of heterogeneous data, deep-learning technology provides reliable prediction results for complex and uncertain phenomena. Recently, it has been increasingly used by horticultural researchers to make sense of the large d...

Spectral imaging is a promising technique for detecting the quality of rice seeds. However, the high cost of the system has limited it to more practical applications. The study was aimed to develop a low-cost narrow band multispectral imaging system for detecting rice false smut (RFS) in rice seeds. Two different cultivars of rice seeds were artifi...
The purpose of this study was to establish an extraction method for the kinsenoside compound from the whole plant Anoectochilus roxburghii. Ultrasound assisted extraction (UAE) and Ultra-high performance liquid chromatography (UPLC) method were used to extract and determine the content of kinsenoside, while response surface method (RSM) was used to...
Chinese narcissus (Narcissus tazetta L. var. chinensis Roem.) is a popular flower in Asia. However, flower colors are limited with all cultivars having a white perianth and yellow corona. Previous studies have shown no anthocyanin accumulation in this species. The reason for an absence of anthocyanins remains unknown, with the flavonoid biosyntheti...
Light is essential for plant growth. Light intensity, photoperiod, and light quality all affect plant morphology and physiology. Compared to light intensity, photoperiod, little is known about the effects of different monochromatic lights on crop species. To investigate how different lighting conditions influence crops with heterogeneous colors in...

... LS-SVR uses radial basis function (RBF) as the kernel function and a grid search (GS) algorithm to find the optimal of model regularization parameters gamma (γ) as well as radial basis function sig2 (σ 2 ) bandwidth. The LS was used to calculate the regression coefficients and deviations value, and the final prediction model was obtained [32,33]. ...
... Zeng et al. [14] utilized lightweight dense scale network to identify corn disease and deployed it on a mobile phone. He et al. [15] used MobileNetV3 to detect citrus Huanglongbing disease with multispectral pictures and dispatched it on a handheld device. Those studies require manual inspection of planting sites. ...
... Shadowing caused by the equipment itself requires consideration. However, hyperspectral images and chlorophyll fluorescence meters [42,51,52] can control interference from an external complex light environment to reduce imaging noise when acquiring pictures. Such sensors generally need to be used with a black box and a controllable light source. ...
... Non-destructive detection is advantageous for picking out disordered fruit without destroying them, which utilizes new computer technologies and collects big data to detect the internal state of the fruit (Yang and Xu, 2021). Changes in physicochemical characteristics during the disorder progress may lead to the variance in optical properties, which could be used to detect the disorder (Peiris et al., 1998). ...
... Despite the desirable classification results obtained by applying MSI in analyzing and detecting the quality of crop seeds, it is still challenging to turn these laboratory-based techniques into more practical applications, owing to the high cost. Thus, a low-cost imaging system capable of obtaining spectral features at specific key wavelengths and viable classification models to monitor crop seed quality are urgently needed [13]. ...
... At the same time, RSM establishes a mathematical model for prediction based on the statistics of data compatibility with polynomial models (Sekhar et al. 2021). It has been widely used as an optimization method for different extraction experiments of polysaccharides, polyphenols, saponins, alkaloids, etc. (Teng and Choi 2012;Yang et al. 2020;Pandey et al. 2018;Raza et al. 2017). The Box-Behnken design (BBD) is convenient to explore the linear effects, quadratic effects and interaction effects of the extraction process (Feki et al. 2021). ...

... However, its flower color is scarce. A few studies have focused on the identification of single pigment-related gene (Li et al. 2013) and the composition of flavonoids and carotenoids (Li et al. 2015), as well as formation of flavonol (Amwar et al., 2019;Wang et al. 2018). In our previous research, we systematically constructed the pigment metabolic pathways and critical structural genes in Narcissus tazetta "Jingzhanyintai" during flower development by transcriptome profiling and pigment metabolite analysis (Ren et al. 2017). ...
... At higher dosage rates, a decrease in PSII energy transfer was found, most likely due to ROS generation caused by gamma radiation, which clearly indicates the dosedependent inhibition of photosynthesis [85]. Another study on Capsicum also proved that high dosages of ionising radiations can act as stress, limiting photosynthetic parameters, whereas at a low dosage, it can act as a stimulant [88]. ...
