“…6 There are some agronomic measures have been used to promote the Se uptake by crops from soil, including intercropping, straw extracts, and phytohormones.

So, screening out additional methods for promoting the Se uptake in crops is necessary.…”

Selenium (Se) is an important trace element for human body, and the fruit Se source is one option for human Se supplementation. To increase grapevine uptake of Se, grape seedlings were transplanted in soils supplemented with sodium selenite, and the concentrations of 0, 1, 2, 4, and 6 g L−1 chitosan were sprayed on grapevine seedling leaves. Next, the effects of chitosan on grapevine Se uptake were studied. The chitosan‐based foliar application increased the biomass, photosynthetic pigment content, antioxidant enzyme activity, and soluble protein content of grapevine. Chitosan application also increased the total Se, inorganic Se, and organic Se contents in grapevine. However, while the root organic Se was increased, the shoot inorganic Se was decreased. Compared to the control, the concentrations of 1, 2, 4, and 6 g L−1 chitosan increased the shoot total Se content by 9.29%, 12.39%, 17.70%, and 14.16%, respectively. Chitosan application also increased the nitrogen (N), phosphorus (P), and potassium (K) contents in grapevine. Moreover, correlation, gray relational, principal component, and cluster analyses revealed that the root total Se, shoot total N, and root total K contents were the top three indicators closely associated with the shoot total Se content. Therefore, foliar‐based chitosan application on grape seedlings can promote the Se uptake in grapevine under sodium selenite supply, and 4 g L−1 is the best concentration.

The phytohormone gibberellic acids (GAs) play a crucial role in the processes of growth, organ development, and secondary metabolism. However, the mechanism of exogenous GA3 regulating the growth and flavonoid synthesis in Phellodendron chinense Schneid (P. chinense Schneid) seedlings remains unclear. In this study, the physicochemical properties, gene expression level, and secondary metabolite of P. chinense Schneid seedlings under GA3 treatment were investigated. The results showed that GA3 significantly improved the plant height, ground diameter, fresh weight, chlorophyll content, soluble substance content, superoxide dismutase, and peroxidase activities. This was accompanied by elevated relative expression levels of Pc(S)-GA2ox, Pc(S)-DELLA, Pc(S)-SAUR50, Pc(S)-PsaD, Pc(S)-Psb 27, Pc(S)-PGK, Pc(S)-CER3, and Pc(S)-FBA unigenes. Conversely, a notable reduction was observed in the carotenoid content, catalase activity and the relative expression abundances of Pc(S)-KAO, Pc(S)-GID1/2, and Pc(S)-GH 3.6 unigenes in leaves of P. chinense Schneid seedlings (p < 0.05). Furthermore, GA3 evidently decreased the contents of pinocembrin, pinobanksin, isosakuranetin, naringin, naringenin, (−)-epicatechin, tricetin, luteolin, and vitexin belonged to flavonoid in stem bark of P. chinense Schneid seedlings (p < 0.05). These results indicated that exogenous GA3 promoted growth through improving chlorophyll content and gene expression in photosynthesis and phytohormone signal pathway and inhibited flavonoid synthesis in P. chinense Schneid seedlings.

An excess of selenium (Se) can cause toxicity to plants. Treatment with melatonin (MT) can alleviate the stress conditions in plants. Limited research exists on the impact of MT on Se stress and uptake in fruit trees. To address Se stress and enhance Se accumulation in Cyphomandra betacea Sendt. (Solanum betaceum Cav.), the effects of exogenous MT (50–200 µmol L−1) on C. betacea growth and Se accumulation under Se stress were studied. MT increased the biomass, photosynthetic pigments levels, and peroxidase activity of C. betacea under Se stress. Only at concentrations of 150 and 200 µmol L−1 did MT increase superoxide dismutase and catalase activities, as well as soluble protein content in C. betacea leaves. MT treatment also boosted the Se content and bioconcentration factor of C. betacea under Se stress while reducing the translocation factor. The dose of MT was directly related to the Se content, and the highest levels of Se in roots and shoots were observed at 150 µmol L−1, which was an increase of 114% and 60%, respectively, compared with the control. In addition, correlation, principal component, cluster, grey, and path analyses revealed a strong correlation between root Se content and shoot biomass with the shoot Se content. Therefore, MT treatment can mitigate Se stress and enhance Se uptake in C. betacea, and the most effective dose of MT is 150 µmol L−1.
