“…When we analyzed differences in sink strength between treatments, we found a marked reduction with P0 treatment, as revealed by decreased values of PNA and SNA. The above may be due to the increased loss of pod and seed development (viability) caused by high daytime as well as nighttime temperatures [ 21 , 36 ], along with a very low supply of P. However, the earliness of both lines may not only be attributed to the high temperature escape response [ 22 , 50 ], but may also be due to the stimulatory effect of P on growth hormones that induce early flowering in common bean plants, as described by Bhattacharya [ 55 ], which translated into a strong correlation between phenological variables (DF and DPM) and yield [ 56 ].…”

Many common bean (Phaseolus vulgaris L.) plants cultivated in areas of the world with acidic soils exhibit difficulties adapting to low phosphorus (P) availability, along with aluminum (Al) toxicity, causing yield loss. The objective of this study was to evaluate the influence of an increase in P supply level on the agronomic, phenological, and physiological performance of two common bean breeding lines grown in acidic soil, with low fertility and under high temperature conditions, in a screenhouse. A randomized complete block (RCB) design was used under a factorial arrangement (five levels of P × 2 genotypes) for a total of 10 treatments with four replications. The factors considered in the experiment were: (i) five P supply levels (kg ha−1): four levels of P0, P15, P30, and P45 through the application of rock phosphate (RP), and one P level supplied through the application of organic matter (PSOM) corresponding to 25 kg P ha−1 (P25); and (ii) two advanced bean lines (BFS 10 and SEF10). Both bean lines were grown under the combined stress conditions of high temperatures (day and night maximum temperatures of 42.5 °C/31.1 °C, respectively) and acidic soil. By increasing the supply of P, a significant effect was found, indicating an increase in the growth and development of different vegetative organs, as well as physiological efficiency in photosynthesis and photosynthate remobilization, which resulted in higher grain yield in both bean lines evaluated (BFS 10 and SEF10). The adaptive responses of the two bean lines were found to be related to phenological adjustments (days to flowering and physiological maturity; stomatal development), as well as to heat dissipation strategies in the form of heat (NPQ) or unregulated energy (qN) that contributed to greater agronomic performance. We found that, to some extent, increased P supply alleviated the negative effects of high temperature on the growth and development of the reproductive organs of bean lines. Both bean lines (BFS 10 and SEF 10) showed adaptive attributes suited to the combined stress conditions of high temperature and acidic soil, and these two lines can serve as useful parents in a bean breeding program to develop multiple stress tolerant cultivars.

“…Growth regulators can alleviate abiotic stresses (salinity, extreme temperatures, drought, etc.) by modulating plant growth and development and improving growth for many plants, whether they are naturally occurring in the plant or added to the plant in order to increase its productivity and improve its efficiency under extreme conditions [22]. In addition, it can act separately or coordinate with other signaling pathways in a complex network.…”

Enhancing Anna Apples’ Productivity, Physico-Chemical Properties, and Marketability Using Sprays of Naphthalene Acetic Acid and Inhibitors of Ethylene for Alleviating Abiotic Stresses

In order to improve the resistance of apples to stresses (abiotic stresses) during hot and dry summers to enhance their productivity and marketability, Anna apple trees were treated with aminoethoxyvinylglycine (AVG), 1-methlcyclopropene (1-MCP), and naphthalene acetic acid (NAA), alone, or in combination, in two successive seasons. All treatments significantly increased the yield per tree, the average fruit volume, fruit diameter, and fruit weight compared to the control (growing under hot and dry summers without any treatments). All treatments significantly reduced the apple size, total soluble solid (TSS) content, anthocyanin content, carotenoid content, total sugar solids, and sugar percentage, and they led to fruit softening, loss of fruit weight, firmness, breakdown percentage, as well as a decreased polyphenol oxidase and peroxidase activity at one-week post-harvest (except for 20-ppm NAA) in comparison with the control. Trees treated with 320-ppm 1-MCP + 250-ppm AVG exhibited maximum yield per tree, fruit firmness, and no-reducing sugars or starch. On the other hand, the 20-ppm NAA produced the maximum TSS content, total sugars, with a reduced sugar percentage, carotenoid and anthocyanin fruit content, and (TSS)/acidity ratio. The application of 320-ppm 1-MCP + 250-ppm AVG effectively delayed the harvest for 14 days compared to the control. Our results show that the sprays of NAA and inhibitors of ethylene had a significant effect on the productivity and marketability of Anna apples under abiotic stresses.

In order to improve Anna apples resistance to hot and dry summer stresses (abiotic stresses) to enhancement the productivity and marketability, Anna apple trees were treated with three growth regulators [naphthalene acetic acid (NAA), 1-methlcyclopropen (1-MCP), and aminoethoxyvinylglycine (AVG)] alone or in combination in two successive seasons. All treatments significantly increased the yield per tree, average fruit volume, fruit diameter and fruit weight compared to control (growing under hot and dry summers which received no treatment). All treatments significantly reduced apple, total soluble solid (TSS) content, fruit softening, anthocyanin content, carotenoid content, total sugar solids, and sugar percentage compared to control. Trees treated with 320-ppm 1-MCP + 250-ppm AVG exhibited maximum yield per tree, fruit firmness, and no-reducing sugars and starch. While 20-ppm NAA produced the maximum TSS content, total sugars, and reducing sugar percentage, carotenoid and anthocyanin fruit content, and (TSS)/acidity ratio. In terms of fruit marketability, the application of all growth regulators remarkably declines the fruit weight loss, fruit firmness loss, and breakdown percentage, as well as decreasing polyphenol oxidase and peroxidase activity at 1-week post-harvest, except for 20-ppm NAA. Additionally, the application of 320-ppm 1-MCP + 250-ppm AVG effectively delayed the harvest for 14 days, whereas the application of NAA effectively moved the harvest date 2 days forward with respect to control. Our results show that specific growth regulator sprays have a significant effect on the productivity and marketability of Anna apples under abiotic stresses
