“…Starch breakdown and sugar synthesis and metabolism is a complex process influenced not only by ethylene but other hormones, the control and interaction of which are not fully understood [ 46 ]. Growing conditions have also been shown to affect the composition of the fruit [ 60 , 61 ]. Thus, it is not unreasonable to presume that differences in ripening conditions, treatments used to control ripening, cultivar, transport times, and other variables influence the ultimate content and relative concentrations of sugars and starch in bananas at the point of consumption.…”

The goal of this work was to evaluate changes in dietary fiber measured by the traditional enzymatic-gravimetric method (AOAC 991.43) and the more recently accepted modified enzymatic-gravimetric method (AOAC 2011.25), mono- and disaccharides, and starch as a function of assessed ripeness in a controlled study of a single lot of bananas and in bananas at the same assessed stages of ripeness from bananas purchased in retail stores, from different suppliers. Sugars, starch, and dietary fiber were analyzed in bananas from a single lot, at different stages of ripeness, and in retail samples at the same assessed stages of ripeness. Mean fiber measured by the traditional enzymatic-gravimetric method (EG) was ~2 g/100g and not affected by ripeness. Mean fiber assessed with the recently modified method (mEG) was ~18 g/100g in unripe fruit and decreased to 4–5 g/100g in ripe and ~2 g/100g in overripe bananas. Slightly ripe and ripe bananas differed by ~1.1 g/100g in the controlled single-lot study but not among retail samples. There was a large increase in fructose, glucose and total sugar going from unripe to ripe with no differences between ripe and overripe. Aside from stage of ripeness, the carbohydrate composition in retail bananas is likely affected by differences in cultivar and post-harvest handling. Results from this study demonstrate the importance of measuring dietary fiber using the mEG approach, developing more comprehensive and sensitive carbohydrate analytical protocols and food composition data, and recognizing the impact of different stages of maturity and ripeness on carbohydrate intake estimated from food composition data.

“…Hence, a high shoot-to-root biomass ratio is plausible. Although the allocation of carbon to the youngest leaves appears to be more dominant than to the root [ 176 , 177 ] yet, higher root-over-shoot growth is observed in certain species subjected to low Mg condition [ 177 ]. As such, Mg starvation reduces the growth of younger leaves compared with that of the roots.…”

Photosynthetic carbon converted to sucrose is vital for plant growth. Sucrose acts as a signaling molecule and a primary energy source that coordinates the source and sink development. Alteration in source–sink balance halts the physiological and developmental processes of plants, since plant growth is mostly triggered when the primary assimilates in the source leaf balance with the metabolic needs of the heterotrophic sinks. To measure up with the sink organ’s metabolic needs, the improvement of photosynthetic carbon to synthesis sucrose, its remobilization, and utilization at the sink level becomes imperative. However, environmental cues that influence sucrose balance within these plant organs, limiting positive yield prospects, have also been a rising issue over the past few decades. Thus, this review discusses strategies to improve photosynthetic carbon assimilation, the pathways actively involved in the transport of sucrose from source to sink organs, and their utilization at the sink organ. We further emphasize the impact of various environmental cues on sucrose transport and utilization, and the strategic yield improvement approaches under such conditions.

“…4, the synergistic effect between many nutrients in chamomile re ects the diverse roles of these nutrients in the growth, yield, and uptake of other nutrients by chamomile. For example, su cient Mg causes a proportional distribution of carbohydrates in the root and shoot; promoting the chamomile root growth (He et al, 2020). On the other hand, Mg affects biomass production and plant growth by proper distribution of carbohydrates and the appropriate allocation of hydrocarbons to different parts of plants (Verbruggen and Hermans 2013) or improving the plant access to N (Haberman et al 2019) and iron (due to its vital role in photosynthesis) (Dong et al 2019) with an effective role in vegetative growth and ultimately the accumulation of plant dry weight.…”

BackgroundWater-deficit stress is one of the most important sources of damage to crop production worldwide. Adopting appropriate varieties using soil microorganisms such as arbuscular mycorrhiza(AM) can significantly reduce theadverseeffectsofwater deficiency.This study is aimed to evaluate the role of Funneliformismosseaeon nutrients uptake and some physiological traits of two chamomile varieties namely Bodgold (Bod) and Soroksári(Sor) under water-deficit stress. The pot experiment was performed in a hydroponic system within a completely randomized design considering four replications. Three levels of water-deficit stress (PEG 6000) were taken into account at water potentials of -0.4 and -0.8MPa. The second factor was AM inoculation.ResultsWater-deficit stress significantly reduced the uptake of macro-nutrients (N, P, and K) and micro-nutrients (Fe, Cu, Mn, and Zn) in the shoots and roots. Moreover, the level of osmolytes (total soluble sugars and proline) and the activity of antioxidant enzymes in the shoots of both varieties increased under water-deficit stress. In the case of Sor variety, the level of these compounds was more satisfactory. AM improved plant nutrition uptake and osmolyte contents while enhancing antioxidant enzymes and reducing theadverseeffectsofwater-deficit stress. Under water-deficit stress, the growth and total dry weight improved upon AM inoculation. ConclusionsIn general, inoculation of chamomile with AM balanced the uptake of nutrients increased the level of osmolytes, antioxidant enzymes, and hence improved plant characteristics under water-deficit stress in both varieties, however, it was more effective in reducing stress damages in Sor variety.
