China Title: Effect of leaf-to-fruit ratio on kernel quality formation of walnut trees Abstract: The study focused on the relationship between leaf-to-fruit ratio (LFR) and walnut kernel quality in Juglans regia 'Wen 185'. It was investigated how LFR influences single kernel weight, the contents and percentages of organic matter in kernels, the 13C distribution proportion (13CDP) in crude fat and protein, and the number and size of oil bodies within the kernels. A gradually decreasing LFR led to reduced single kernel weight, the contents of crude fat, crude protein, and soluble sugar dramatically (P < 0.05), with no significant changes in the percentages and (13CDP) of crude fat, crude protein, and soluble sugar (P > 0.05). Moreover, there were no significant differences in the number of oil bodies per unit area and the size of oil bodies in kernel cotyledons and endosperm storage cells among the different LFR (P > 0.05). We propose that the walnut kernel quality depends on the proportion of sugar converted into fat and protein in the kernels, that the changes in LFR affect the amount of sugar accumulated in kernels but not the proportion of sugar converted to fat and protein, and that the LFR, therefore, have no effect on the percentages of crude fat and crude protein in walnut kernels.

Over a four-year period (2017-2020), temporal variations in flowering were evaluated in 'Honeycrisp' apple trees on eight rootstocks (G.30, G.969, G.202, G.41, G.11, M.9T337, M.26 EMLA and V.6) planted in 2014 in Chihuahua, México. Among the variables evaluated were the probability of late-spring frost, winter chill units, growing degree days, flowering period, foliar nutrient concentrations, trunk cross-sectional area, number and weight of fruit per tree, and production efficiency. Significantly different chill unit accumulations occurred over the four years, with values falling between 974 and 1 415, where for the latter value, the start of flower opening was earlier, but there was a higher risk of damage by temperatures ≤ -2 °C. There was no effect of rootstock on the time of onset and end of flowering. The most productive combinations were 'Honeycrisp' on G.969, G.11 and V.6 with yield estimates of 35 300, 34 200 and 33 600 kg/ha, respectively. The commercial production of 'Honeycrisp' apple trees requires the evaluation of their agronomic performance with different rootstocks. Flowering is particularly important since this phenological stage is so closely linked to productivity and is strongly affected by variations in winter temperatures.

Nevertheless, one significant challenge for gerbera flowers is their relatively short vase life. Commercially, synthetic chemicals are used to prolong the vase life of flowers; however, they are not environmentally friendly, posing sustainability concerns. Therefore, we used different concentrations of the biocontrol spore suspension of Streptomyces exfoliatus FT05W and evaluated their effect on vase life, bacterial population, and different morphology and physiological indices of gerbera cut flowers, with the objective of determining the optimal concentration for maximum efficiency. The results revealed that all spore suspensions of S. exfoliatus FT05W (1 × 106 CFU mL) significantly extended vase life and were 4 days longer than the control. S. exfoliatus FT05W treatment also increased bottle life extension days, blossom diameter, and fresh weight, and maintained water balance. In addition, it decreased malondialdehyde (MDA) levels and relative electrolyte leakage (REL), leading to decreased oxidative stress. S. exfoliatus FT05W significantly increased antioxidant enzymes, including superoxide dismutase (SOD) activity, catalase (CAT) activity, peroxidase (POD) activity, soluble sugar (SS), and soluble protein (SP), compared to the control. Furthermore, it can effectively inhibit bacterial proliferation, resulting in a decline in colonies and a significant delay in the flower ageing process. The beneficial impacts of S. exfoliatus FT05W were most pronounced at a concentration of 1 × 106 CFU/mL. The findings of this research suggest that S. exfoliatus FT05W has great potential as a bio-fertiliser for cut flowers, as it is capable of addressing the challenges associated with flower cultivation.

Abstract: In recent years, grafting has emerged as an efficient and alternative tool to the relatively slow conventional breeding methods, aiming to increase tolerance to abiotic stresses and soil pathogens while improving yield and quality attributes in fruit vegetables. In the present investigation, six inter-specific cucurbitaceous rootstocks, viz. sponge gourd (SG), ridge gourd (RG), ash gourd (AG), bottle gourd (BG), and Summerfit (SF), an inter-specific hybrid of snap melon × acidulus melon, were evaluated for cucumber (C) cv. 'Kashi Nutan'. Experimental findings revealed that cucumber grafted onto inter-specific SF exhibited a 14.63%, 57.5%, and 20.05% increase in vine length, number of branches, and dry matter production, respectively, compared to the self-rooted control. Photosynthetic parameters such as photosynthetic rate (Pn), stomatal conductance (gs), and maximum quantum efficiency of photosystem II (PS II) (Fv/Fm) were also higher in cucumber leaves grafted onto the SF rootstock. Compared to self-rooted plants, cucumber grafted onto SF recorded 72.3% more fruits, a 36.9% increase in fruit weight, and an 80.9% higher fruit yield. The SF rootstock also showed a 44.54% increase in total root length (TRL), a 77.11% increase in root volume, and a 27.25% increase in average root diameter over self-rooted cucumber.

The mentioned problems appear more in areas with hot and humid summers. The research focused on the quality of the kernel in terms of colour and marketability, as well as the dry matter of the kernels. Additionally, the ease of mesocarp separation from endocarp was examined. Experimental trials were designed with 27 treatment combinations to address the mentioned issues using varying concentrations of 2-chloroethylphosphonic acid (ethephon) at different harvest dates. In this study, using 1 920 ppm of ethephon on August 22nd resulted in the best quality walnut kernels and mesocarp. Researchers in this project successfully achieved the highest quality of walnut kernels and nuts in a region where over 90% of the harvest consisted of dark-kernel walnuts.

TOR3209 induces plant tolerance in a wide range of stress conditions. However, the protection of photosystem under cold stress has not been fully understood. Here we reported that the photochemistry activity of photosystem II (PSII) was increased in tomato plants receiving TOR3209 treatment, including the maximum quantum efficiency of PSII photochemistry (Fv/Fm), PSII operating efficiency (ΦPSII), PSII maximum efficiency (Fv'/Fm'), and non-photochemical quenching (NPQ). Microscopic study revealed that the integrity of chloroplast structure was greatly improved by TOR3209, which was damaged at low temperature. Moreover, TOR3209 treatment resulted in good protection on leaf stomatal and guard cell size. In response to TOR3209 treatment, the intercellular CO2 concentration (Ci) and stomatal limitation values (Ls) were decreased while the mesophyll conductance (gm) and chloroplast CO2 concentration (Cc) were increased. The carotenoid content in TOR3209-treated tomato was accumulated at a higher level, which was involved in photoprotection and biosynthesis of abscisic acid (ABA), as well as the increased amounts of ABA in the leaves were subsequently verified in the plants treated with TOR3209. These results demonstrated that TOR3209 treatment comprehensively protected tomato photosynthesis at low temperatures.

Plants were grown in a growth chamber under LED (light-emitting diode) cold white, red and blue light and under fluorescent cold white light (control). The results showed that white and blue light treatments were the best for microgreen growth. Higher concentration of pigments was recorded in plants grown under LED light compared to those grown under FL (fluorescent lamp) light. The content of phenols and flavonoids had a positive and significant correlation with DPPH (2,2-diphenyl-1-picrylhydrazyl) antioxidative capacity (r = 0.66 and r = 0.90, respectively). The first two principal components account for 97.92 % of the total variation of all observed traits in this trial. Based on the PCA (principal component analysis) results, it can be concluded that the traits total phenols content, carotenoid content, chlorophyll a and b content make up the largest share of variability in the obtained results and that the red light conditions were the most unfavourable for the content of phytochemical compounds and antioxidant potential.
