“…Then, similar effects of ALA were reported in peaches [252], pears [253,254], grapes [255][256][257][258], litchi [259,260], pomegranates [261], and mangoes [262]. In addition to fruit coloration, soaking wheat seeds with 50 mg L −1 ALA not only improves frost tolerance but also increases anthocyanin accumulation in coleoptiles [263].…”

The review briefly introduces the natural occurrence, physicochemical properties, and biosynthesis of 5-aminolevuinic acid (ALA) and highlights a variety of applications in the planting industry and its possible mechanisms. It has been known that ALA can be used as biological pesticides, fungicides, and herbicides when the concentrations are higher than 838 mg L−1 (about 5 mmol L−1). When ALA concentrations are 100–300 mg L−1, it can be used to thin surplus flowers in the spring of orchards and promote fruit coloration before maturation. When the concentrations are lower than 100 mg L−1, especially not higher than 10 mg L−1, ALA can be used as a new plant growth regulator to promote seed germination, plant (including root and shoot) growth, enhance stress tolerance, increase crop yield, and improve product quality. In photosynthesis, ALA is involved in the regulation of the whole process. In stress tolerance, ALA induces plant preventive and protective systems through the NO/H2O2 signaling network. In secondary metabolism, ALA regulates many gene expressions encoding transcription factors or function proteins to promote anthocyanin and flavonol biosynthesis and accumulation. In general, ALA promotes plant health and robustness, reduces the use of chemical fertilizers and pesticides—which is conducive to improving the ecological environment, human production, and living conditions—and has a broad application prospect in agroforestry production. As a new plant growth regulator with multiple and powerful functions, the underlying regulatory mechanisms need more study.

“…Anthocyanin has a specific antioxidant effect [2], which can protect winter wheat from oxidative damage. Increasing its value can improve stress tolerance and disease resistance and promote the growth and development of winter wheat [3]. However, a decrease in its value will cause impaired photosynthesis, decreased antioxidant capacity, and weakened stress tolerance in winter wheat, leading to growth and development limitations.…”

“…Then, three MLs and three corresponding GA_MLs were constructed with SBS, VIo2, and VIo3 as input variables for estimating the values of anthocyanin in winter wheat leaves, respectively. The research objectives of this paper were (1) to compare the performance of all models and to investigate the potential of MLs(SBS) and MLs(VIo) for estimating anthocyanin values at four fertility stages of winter wheat; (2) to analyze the effect of FDS on the input variables SBS and VIo for estimating anthocyanin values in winter wheat, and to dissect the accuracy of anthocyanin prediction model and its influencing factors; (3) to Analyze the optimization effect of genetic algorithm on the model. The results of this study will provide some technical support for the potential application of hyperspectral technology in detecting and diagnosing anthocyanin in winter wheat.…”

Anthocyanin can improve the stress tolerance and disease resistance of winter wheat to a certain extent, so timely and accurate monitoring of anthocyanin content is crucial for the growth and development of winter wheat. This study measured the ground-based hyperspectral reflectance and the corresponding anthocyanin concentration at four key growth stages—booting, heading, flowering, and filling—to explore the spectral detection of anthocyanin in winter wheat leaves. Firstly, the first-order differential spectra (FDS) are obtained by processing based on the original spectra (OS). Then, sensitive bands (SBS), the five vegetation indices for optimal two-band combinations (VIo2), and the five vegetation indices for optimal three-band combinations (VIo3) were selected from OS and FDS by band screening methods. Finally, modeling methods such as RF, BP, and KELM, as well as models optimized by genetic algorithm (GA), were used to estimate anthocyanin content at different growth stages. The results showed that (1) among all the models, the GA_RF had incredible performance, VIo3 was the superior parameter for estimating anthocyanin values, and the model GA_RF of FDS data based on VIo3 for the filling stage (Rv2 = 0.950, RMSEv = 0.005, RPDv = 4.575) provided the best estimation of anthocyanin. (2) the first-order differential processing could highlight the degree of response of SBS, VIo2, and VIo3 to the anthocyanin values. The model performances of the FDS were better than that of OS on the whole, and the Rv2 of the optimal models of FDS were all greater than 0.89. (3) GA had optimizing effects on the RF, BP, and KELM, and overall, the GA models improved the R2 by 0.00%-18.93% compared to the original models. These results will provide scientific support for the use of hyperspectral techniques to monitor anthocyanin in the future.
