“…Accordingly, under root hypoxia, we found a significant increase in electrolyte leakage, a condition which is strongly associated to a loss of the integrity of the cell membranes in tomato plants [28]. This hypothesis is consistent with the observed promoting effect of lipid peroxidation in leaf cells under root hypoxia [29]. The present correlation analyses bear this out, as the electrolyte leakage was positively associated to F 0 , and negatively to F V /F M , A N , E and gs.…”

Chlorophyll Fluorescence, Photosynthesis and Growth of Tomato Plants as Affected by Long-Term Oxygen Root Zone Deprivation and Grafting

A greenhouse experiment was conducted to study the effects of the O2 root zone level and grafting on chlorophyll fluorescence, photosynthesis and growth of cherry tomato grown in a hydroponic system. Two O2 concentrations in the root zone, namely Ox (saturation level) and Ox- (2–3 mg L−1), were applied for 30 days on self-grafted cherry tomato Dreamer or grafted onto the hybrids Arnold, Beaufort, Maxifort and Top Pittam. Root hypoxia increased minimum fluorescence (by 10%) while it decreased variable fluorescence and the maximum quantum yield of PSII (up to 16 and 8%, respectively). Moreover, it reduced leaf photosynthesis, transpiration and stomatal conductance (by 12, 17 and 13%, respectively), whereas it increased leaf electrolyte leakage (by 2.1%). The graft combinations showed a different ability in buffering the effects of root hypoxia on plant growth and related components, and these differences were related to their root biomass. The minimum fluorescence was negatively correlated to plant growth, so it may be a useful indicator to select tolerant rootstocks to root hypoxia. Our results suggest the occurrence of both diffusive and metabolic constraints to tomato photosynthesis under root hypoxia, a condition that can be mitigated by selecting rootstocks with a more developed root system.

“…Use of different exogenous protectant to overcome waterlogging/flooding is common in plant science, but the potential use of GB in alleviating the effects of waterlogging/flooding stress in plants is very rare. Rasheed et al [105] investigated the effect of GB on the growth and physiology of tomato plants under waterlogged conditions (Tab. 3).…”

In the era of climate change, abiotic stresses (e.g., salinity, drought, extreme temperature, flooding, metal/metalloid(s), UV radiation, ozone, etc.) are considered as one of the most complex environmental constraints that restricts crop production worldwide. Introduction of stress-tolerant crop cultivars is the most auspicious way of surviving this constraint, and to produce these types of tolerant crops. Several bioengineering mechanisms involved in stress signaling are being adopted in this regard. One example of this kind of manipulation is the osmotic adjustment. The quarternary ammonium compound glycinebetaine (GB), also originally referred to as betaine is a methylated glycine derivative. Among the betaines, GB is the most abundant one in plants, which is mostly produced in response to dehydration caused by different abiotic stresses like drought, salinity, and extreme temperature. Glycinebetaine helps in decreased accumulation and detoxification of ROS, thereby restoring photosynthesis and reducing oxidative stress. It takes part in stabilizing membranes and macromolecules. It is also involved in the stabilization and protection of photosynthetic components, such as ribulose-1, 5-bisphosphate carboxylase/oxygenase, photosystem II and quarternary enzyme and protein complex structures under environmental stresses. Glycinebetaine was found to perform in chaperone-induced protein disaggregation. In addition, GB can confer stress tolerance in very low concentrations, and it acts in activating defense responsive genes with stress protection. Recently, field application of GB has also shown protective effects against environmental adversities increasing crop yield and quality. In this review, we will focus on the role of GB in conferring abiotic stress tolerance and the possible ways to engineer GB biosynthesis in plants.

“…Se was demonstrated to improve the quality of treated plants, including tomatoes [16]. Glycine betaine was recently reported to increase the quality of the tomato fruits from plant submitted to waterlogging stress [37]-and therefore, for plants grown under stress. However, to the best of our knowledge, our study is the first-one regarding the effects of the combination between BYV/glycine betaine with Se on tomatoes fruit quality.…”

“…Glycine betaine is an osmoprotectant/compatible solute, i.e., a substance highly soluble in water, which protects the proteins from denaturation and enhances plant tolerance to abiotic stress [30,31]. Exogenous glycine-betaine, applied as foliar treatment to tomatoes, enhances plant response to various types of abiotic stress-drought [32,33], salinity [32,34], chilling [35], high-temperatures [36], and water logging [37].…”

Plant Biostimulant Effects of Baker’s Yeast Vinasse and Selenium on Tomatoes through Foliar Fertilization

et al. 2020

The application of selenium (Se) to tomatoes enhances accumulation of bioactive compounds. The physiological window of Se is very narrow, and Se overdose reduces the yield. Glycine betaine was shown to reduce Se’s negative effects on plants and to potentiate its beneficial effects. In this study, baker’s yeast vinasse (BYV), as an affordable source of glycine betaine, was tested for its interaction with Se in an optimized foliar fertilizer. The application dose was selected after a laboratory experiment, wherein assays on plant height, leaves surfaces, stomatal conductance, and chlorophyll fluorescence were done. The Se and BYV supplemented foliar fertilizers were tested for their effects on accumulation of bioactives in drip-irrigated tomatoes cultivated in a greenhouse. Under laboratory conditions, assays demonstrated Se and BYV induced effects on tomatoes plants. Both the stomatal conductance and photosynthesis efficiency increased compared to a water treated control. The greenhouse experiment demonstrated that BYV and Se addition increases the number of tomato fruits in the “extra” marketable class and enhances the accumulation of ascorbic acid, carotenes, polyphenols, and flavonoids. The effects depend on the composition of the foliar fertilizer, the most significant effects being recorded for the foliar applied product with the highest BYV and nitrogen content.
