“…All of these growth-promoting characteristics mentioned can be found in PGPR. One of the most important is the production of IAA, which is one of the most physiologically active auxins (phytohormones) and plays a key role in different processes during plant development, such as increasing the length and number of roots, density of root hairs, enhancement of nutrient uptake, induction of flowering buds, and fruit setting [ 16 , 17 , 18 , 19 ]. Iron solubilization by siderophores is also crucial for plants, considering that iron in soil occurs mostly in non-bioavailable forms [ 20 ].…”

Current agricultural methodologies are vulnerable to erratic climate and are dependent on cost-intensive fertilization to ensure high yields. Sustainable practices should be pursued to ensure food security. Phaseolus vulgaris L. is one of the most produced legumes worldwide and may be an alternative to reduce the environmental impact of meat production as a reliable source of high-quality protein. Plant growth-promoting rhizobacteria (PGPR) are emerging as a sustainable option to increase agricultural production. To understand the dynamics between plants and microorganisms, the culturable microbiota of bean roots was isolated and identified at distinct stages of plant development (early and late vegetative growth, flowering, and pod) and root compartments (rhizoplane, endosphere, and nodules). Diversity and abundance of bacteria associated with root compartments differed throughout the plant life cycle. Bacterial plant growth promotion (PGP) and protection abilities (indole-3-acetic acid production, siderophore synthesis, and antifungal activity) were assessed and associated with plant phenology, demonstrating that among the bacteria associated with plant roots, several strains had an active role in the response to plant biological needs at each stage. Several strains stood out for their ability to display one or more PGP traits, being excellent candidates for efficient stage-specific biostimulants for application in precision agriculture.

“…Many studies have reported that drought can induce flowering in several plant species, including durian [10,11], mango [15], citrus fruits [9], longan [13], lime [12], loguat [14], and mangosteen [17]. A drought period lowers soil moisture and increases soil temperature.…”

“…Many studies have shown that mangosteen reproductive phenology (i.e., flowering and fruiting) is associated with climatic conditions (e.g., rainfall, temperature, radiation levels, and photoperiod), height above sea level, availability of shade, and geographical locations [2][3][4][5][6][7][8]. Drought-inducing flowering has been reported in several plant species, including citrus fruits [9], durian [10,11], lime [12], longan [13], loguat [14], mango [15], and mangosteen [5,16,17]. Many studies have reported that drought-inducing flowering in mangosteens with 15-30 dry days for flower bud formation and flowering, occurs naturally after the dry period [2,3,5,[17][18][19].…”

The objective of this study was to investigate the differences in climatic factors and fruit quality between on- and off-season production periods. Climate, soil, and mangosteen measurements were all studied during on- and off-season production. We chose 40 mangosteen trees and observed flowering and fruit set rates over two production periods. The results showed that the number of flowers per branch, the number of fruits per branch, the circumference of fruits, and the fruit weight were higher during the on-season mangosteen production period than during the off-season mangosteen production period. However, the number of edible pulp segments, peel thickness, percentage of translucent flesh, and fruit gumminess were lower in the on-season mangosteen production period than in the off-season mangosteen production period. The percentage of fruit scars did not differ between the on- and off-season mangosteen production periods. When compared to the on-season mangosteen production period, there was lower relative humidity, soil moisture at 120 cm depth, and leaf wetness at 15 cm above ground during the off-season mangosteen production period; however, there was higher air temperature, soil moisture, and soil temperature at all four depth levels.

“…GA3-promoted flower bud differentiation may be related to the activation of FT genes for flowering [30,31]. In addition, ZT is one of the cytokinins that coordinate flower bud differentiation with genes such as 7FL1 and AP1 and usually acts to promote bud differentiation [32][33][34]. In our study, ZT in buds was significantly lower than the ZT in buds of T2, which was opposite to the trend with ABA, Plant flower bud differentiation is closely related to endogenous hormones and is regulated in various ways, for example, by influencing nucleic acid, protein or enzyme activity.…”

To explore the reasons for the differences in flower bud differentiation in Camellia oleifera under different sink–source relationships, different types of new shoots (T1 and T2) were selected to represent different sink–source relationships (new shoots with one fruit borne alongside at the bottom of the new shoots-T1; new shoots without one fruit borne alongside at the bottom of the new shoots-T2), and the flower bud differentiation rate, endogenous hormones and photosynthetic characteristics were determined. With the increase in the sink, the flower differentiation rate decreased significantly and the IAA and GA3 content in the leaves and ABA content in the buds increased significantly, while the GA3 and ZT content in the buds decreased significantly, which were significantly and positively correlated with the flower differentiation rate, with correlation coefficients of 0.777 and 0.817, respectively. Furthermore, an increase in the number of sinks contributed significantly to the increase in soluble sugar and starch content in leaves, while the soluble sugar and starch content in flower buds decreased significantly with the increase in sinks, with maximum differences of 3.45 mg·g−1 (soluble sugar in leaves), 4.09 mg·g−1 (soluble sugar in flower buds), 7.08 mg·g−1 (starch in leaves) and 4.87 mg·g−1 (starch in flower buds), and the high soluble sugar and starch content in flower buds at preflower bud differentiation with correlation coefficients of 0.854 and 0.837, respectively. The chlorophyll content and net photosynthetic rate increased with increasing sinks. In the presence of fruit at the base of the new shoot, more 13C assimilates were allocated to fruit and less to flower buds, resulting in a decrease in the rate of flower bud differentiation. The 13C assimilate allocated to the flower buds of T1 (6.71 mg·g−1) was significantly lower than the 13C assimilate allocated to the flower buds of T2 (10.26 mg·g−1) during late bud differentiation, and the difference between T1 and T2 was greatest during this period. Our work demonstrated that the sink–source relationship regulated Camellia oleifera flower bud differentiation by influencing endogenous hormones and photosynthetic characteristics. To achieve stable production of Camellia oleifera in successive years in the future, the ratio of the number of new shoots of the two types in relation to the different sink–source relationships should be reasonable.
