“…According to the sampling method reported by Ma et al, the open-field soils were collected from agricultural soil planting with wheat, which are irrigated less than five times during the growing period of wheat (7–9 months) . In the greenhouses, vegetables and fruits are the main crop products, which are generally irrigated every 10 days and operated all year round . All the soil samples were from non-rhizosphere to minimize the impacts of rhizosphere effects of different crops.…”

Perfluoroalkyl substances (PFASs) are widely present in agricultural soils, but their sources and fate in greenhouse soils remain unclear. In this study, the sources, fractionation, and migration of PFASs were compared in the greenhouse and open-field soils of the Fen-Wei Plain, China. The total concentrations of PFASs (Σ17PFAS) were comparable in the greenhouse and open-field soils but with different profiles. Detrended correspondence and correlation analyses indicated that dry deposition was an important source of PFASs in the open-field soils, whereas surface water had a notable contribution to the greenhouse soils due to more frequent irrigation. The PFASs in the soils were mainly present in water-soluble fraction (F1). The F1 proportions of short-chain and long-chain PFASs were negatively correlated with the anion exchange capacity (AEC) and organic carbon content (f oc) in soil, respectively, with that of short-chain PFASs being higher than long-chain ones. The AEC was significantly higher while f oc was lower in the greenhouse soil than the open-field soil, leading to lower proportions of F1 for short-chain PFASs while higher for long-chain ones in the greenhouse soil. Frequent irrigation and elevated temperatures promoted the migration of PFASs in greenhouse soil; thus, the Σ17PFAS and F1 exhibited an increasing trend with soil depth.

“…In recent years, a series of studies examined the high yield and resilience to adversity of pineapple, including various studies on flowering [ 43 – 46 ], reduction of browning [ 47 – 50 ], quality and harvest [ 51 – 54 ], growth and ripening changes [ 55 ], salt tolerance [ 56 ], tissue culture and breeding [ 57 – 60 ], growth of seedlings [ 61 ], irrigation of cultivation [ 62 ], the effects of drought on growth [ 39 ], and the effects of high temperatures postharvest [ 63 ]. Despite pineapples being drought-tolerant, extreme and persistent drought exert negative impacts on yield, requiring attention to be paid to this issue.…”

Effect of plant growth regulators DA-6 and COS on drought tolerance of pineapple through bromelain and oxidative stress

et al. 2023

Background Due to global warming, drought climates frequently occur on land, and despite being drought resistant, pineapples are still subjected to varying degrees of drought stress. Plant growth regulators can regulate the stress tolerance of plants through hormonal effects. This experiment aims to investigate the regulatory effects of different plant growth regulators on Tainong- 16 and MD-2 Pineapple when subjected to drought stress. Results In this experiment, we examined the regulatory effects of two different plant growth regulators, sprayed on two pineapple varieties: MD-2 Pineapple and Tainong-16. The main component of T1 was diethyl aminoethyl hexanoate (DA-6) and that of T2 is chitosan oligosaccharide (COS). An environment similar to a natural drought was simulated in the drought stress treatments. Then, pineapples at different periods were sampled and a series of indicators were measured. The experimental results showed that the drought treatments treated with T1 and T2 plant growth regulators had a decrease in malondialdehyde, an increase in bromelain and antioxidant enzyme indicators, and an increase in phenotypic and yield indicators. Conclusion This experiment demonstrated that DA-6 and COS can enhance the drought resistance of pineapple plants to a certain extent through bromelain and oxidative stress. Therefore, DA-6 and COS have potential applications and this experiment lays the foundation for further research.
