Synthesized auxins, ethylene, abscisic acid, cytokinin, and gibberellins are only a few of the key PGRs that have been studied and used for quite a long period of time. brassinosteroids, salicylic acid, jasmonic acid, CPPU (N-(2-chloro-4-pyridyl)-N'-phenylurea), putrescine, hexanal, triacontanol, melatonin, and other chemicals have been added to the list of PGRs. These PGRs can be considered the new generation of plant growth regulators. These relatively novel hormones are critical for a plant's growth and development. They aid in the increase of not only the quantity (fruit set, length, weight, yield, volume, pulp percentage, and so on) but also the quality of fruit crops (fruit colour, firmness, total soluble solids, total sugar, ascorbic acid content, etc). They also help to prolong the shelf life of certain fruits and minimize the losses after harvesting. As a result, these new-generation PGRs can be used to boost an orchard's productivity and income while minimizing pre and post-harvest losses to the greatest extent possible. Hence, this extensive review discusses the impact of these new-generation PGRs on fruit crops.

The total phenolic content determined by the spectrophotometric method using Folin-Ciocalteu reagent varied from 34.84 to 149.28 to mg GAE/100 g FW depending on the cultivar/rootstock combination. The concentration of total anthocyanins was determined by using the pH-differential method and it ranged from 0.46 to 11.54 mg CGE/100 g FW. Highest level of the total phenolic content and concentration of the total anthocyanins content was detected in the cultivar 'Regina' grafted onto the Gisela 6 rootstock. Neochlorogenic acid, catechin, chlorogenic acid and quercetine-3-O-glucoside were detected using HPLC method. Significant variation of detected individual polyphenols in sweet cherry fruits grafted on different rootstocks was observed. The lowest content of individual polyphenols was measured in 'Regina' cultivar grafted on the SL 64. Ferric reducing antioxidant power assay indicated that all investigated fruits possessed similar antioxidant activity. There was a statistically significant correlation observed between the total phenolic content and antioxidant activity (correlation coefficient 0.972, P-value below 0.01), as well as between the anthocyanins and antioxidant activity (correlation coefficient 0.855, P-value below 0.01).

It was found that there were 134 differential metabolites. These differential metabolites were enriched in 40 metabolic pathways. Studies on the biosynthetic pathways and regulatory mechanisms of metabolites in sweet cherry leaves showed that low-light and drought stresses in RS plants were related to the amino acid biosynthesis metabolic pathway and that of flavone and flavonol biosynthesis. Sweet cherry trees exhibited improved tolerance to drought stress by regulating the increase in the content of metabolites, such as proline in the amino acid metabolic pathway and the content of flavonoids in the phenylpropane metabolic pathway. To cope with low-light stress, sweet cherry leaves can increase their photosynthetic efficiency by regulating the flavonol content in the flavone and flavonol biosynthetic pathway under the catalysis of a series of enzymes.

Abstract: Seed deterioration resulting from production and storage factors is the major cause of differences in the seed vigour that results in low seedling emergence in both the laboratory and in the field. An experiment was conducted to evaluate the effect of seed invigoration by osmo-conditioning on the radicle emergence and the physiological parameters of naturally deteriorated seed lots of the true seed of shallots. The experiments were arranged in a completely randomised design with a repeated measurement for radicle emergence and a randomised complete block design for seedling vigour in the field with four replicates. The results indicated that the radicle emergence of the invigorated seed with ZnSO4 correlated well with the seed viability and vigour parameters for seed lots stored under uncontrolled conditions. The radicle emergence of invigorated seeds stored under the uncontrolled condition were more predictive and strongly correlated with the seedling vigour parameters in the field, i.e., the field emergence, field emergence rate and mean emergence time with r = 0.968, r = 0.970 and r = -0.947, respectively. Furthermore, the coefficients of determination were significant (P < 0.05) with R2 = 0.936 field emergence, R2 = 0.941 field emergence rate and R2 = 0.898 for the mean emergence time. Seed invigoration with 0.5% ZnSO4 further significantly reduced the time of a single count of RE from 72 hours and 68 hours to 60 hours with field prediction rates ranging from 90-99%. It was concluded that the radicle emergence of TSS can be improved by invigorating the seeds with 0.5% ZnSO4 thereby increasing the germination percentage, vigour index, and germination rate and reducing the mean germination time.

China Title: Metabolite changes in cucumber xylem sap under rhizosphere aeration Abstract: The impact of rhizosphere aeration on the composition of xylem sap in cucumber grown in soil was studied to determine its effects on (i) water and nutrient uptake, (ii) xylem transport, and (iii) amino acid synthesis in the roots. Plants grown under three different aeration conditions were subjected to progressive gas stress throughout the whole growth period. The shoot and root growth, xylem nitrate (NO3-) concentration, potassium (K+) concentration, xylem sap flow rate, and amino acid concentrations were higher in the Z1 treatment plants than in the control (CK) plants, and the former also showed a lower CO2 (0.25-0.84%) and a higher O2 (18.22-20.02%). However, the Z3 treatment plants exhibited decreased xylem loading of amino acids, NO3- concentrations, and K+ concentrations and a lower flow rate of xylem sap, which restricted shoot and root growth due to poor aeration caused by a higher CO2 (0.75-3.68%) and a lower O2 (11.51-18.6%). Furthermore, the xylem pH in these plants was lower by approximately 0.17 units, and the conductivity was decreased by approximately 0.31 mS/cm. Based on the observed results, the CO2 and O2 in the soil can potentially regulate root and shoot growth and the xylem sap composition in cucumber. Therefore, rhizosphere aeration is important for the vigorous growth of plants.

China Title: Identification of tomato circular RNAs in response to Botrytis cinerea Abstract: Botrytis cinerea is one of the main pathogens that harm the tomato yield and cause huge economic losses worldwide. Studies of circRNAs in response to the stress caused by pathogens have received more and more attention in tomato and other model crops. In this study, four groups were treated with ZaoFen (ZF), CuiLi (CL) (susceptible and tolerant genotypes to B. cinerea, respectively), ZFBc, CLBc (48 hour response to a B. cinerea infection). A total of 918 circRNAs were identified, among which exonic circRNAs (70.70%) accounted for the majority of them, and 118 circRNAs (12.85%) were located in chr1. A total of 18 (1.96%) circRNAs were shared among the four libraries. A total of 6 circRNAs showed fold changes in the differential expression analysis between the time and cultivar control groups, and circRNA115, circRNA145 and circRNA223 repeatedly appeared in the different control treatments. Notably, the gene targeted by circRNA115 was an ethylene-forming enzyme. At the same time, we predicted the target genes of the six circRNAs obtained in the study, and a total of 319 miRNAs were predicted. This study contributes to the mechanism in response to B. cinerea stress in the tomato, and paves the way for the further study of circRNAs under tomato pathogen stress.

This study aims to test whether the drought tolerance of chrysanthemums can be improved by brassinolide and to clarify the underlying physiological mechanism. An own-root chrysanthemum and a corresponding grafted-root line (Artemisia annua rootstock) were treated with brassinolide under three water levels in a randomised complete block design with five replications. The results showed that brassinolide increased the relative water content, net photosynthetic rate, chlorophyll (Chl) fluorescence parameters, Rubisco, ascorbate peroxidase, glutathione reductase, dehydroascorbate reductase and monodehydroascorbate reductase activities, ascorbate/dehydroascorbate, glutathione/oxidised glutathione and dry mass, and reduced the H2O2 content in the own-root and grafted-root chrysanthemums, especially under drought stresses. The magnitude of the changes to the parameters was greater in the own-root line than in the corresponding grafted-root line under brassinolide treatment. The above parameters showed significant differences (P < 0.05) between the brassinolide chrysanthemums and the corresponding non-brassinolide chrysanthemums under drought stresses. This might be the physiological mechanism of improved drought tolerance by brassinolide in chrysanthemums.
