“…The discrepancy might be because the response of SD to environmental stress is non‐monotonic, but has a threshold (Xu and Zhou, 2008) and depended on plant varieties (Guo et al, 2018). No matter how SD responded to environmental stress, SD and a max were still the main determinants of g smax (Gilbert and Medina, 2016; Haworth et al, 2013; Lawlor, 2013; Putra et al, 2012; Zhu et al, 2016), which were consistent with our study (Figure 2). We came to more specific conclusions that g smax was determined by both SD and a max across different salt levels under W1, whereas g smax was more affected by a max than SD under W2 (Figure 2).…”

“…Stomata are the main gate for water and carbon exchanges between plant leaves and the environment. The maximum opening of stomata can be characterized by maximum stomatal conductance ( g smax ), which is determined by stomatal area ( a max ) and stomatal density ( SD ) (Gilbert and Medina, 2016; Haworth et al, 2013; Lawlor, 2013; Putra et al, 2012; Zhu et al, 2016). Stomatal conductance ( g s ), a measure of the degree of stomatal opening, is determined by g smax , and the actual apertures of stomatal pores (Leakey et al, 2019).…”

Stomatal conductance (g s ) affects water use efficiency (WUE) through coordinating photosynthesis and transpiration and is regulated by chemical and/or hydraulic signals. However, the regulation mechanism of g s of tomato leaves has not been fully explored under combined water and salt stress. Here, we set up four salt treatments and two water treatments in a climate greenhouse and measured stomatal morphologies and conductance and other photosynthesis parameters. Water and salt stress reduced stomatal length (SL), width, perimeter, area (a max ), density (SD), and the maximum stomatal conductance (g smax ). Water and salt stress had a separate weakening effect on net photosynthetic rate (A) and transpiration rate but interactively reduced g s . The contents of abscisic acid (ABA) and Na + in tomato leaves increased with the NaCl concentration, while leaf water potential (Ψ l ) and chlorophyll content decreased. Under full irrigation, g smax was coordinated by SD and a max , and g s by ABA content under salt stress. Under water and salt combined stress, g smax was affected by a max , and g s was coordinated with ABA and Ψ l . The decrease of A was caused by both a reduction of chlorophyll content and g s under water and salt stress. Intrinsic WUE did not reduce under full irrigation or mild to moderate salt stress but decreased under a combination of water and severe salt stress, indicating that the leaves of the tested tomato cultivar performed better under moderate salt stress.Collectively, these results can provide useful insights for the efficient management of water and salt to adapt to drought and high salt environments.

“…Proline (Pro) is considered a biochemical indicator of stress due to the improvement of these levels in plants exposed to heat, resulting in a destruction or decrease in protein biosynthesis, as well as through their negative effect on membrane stability (Putras et al 2012). Current results suggest that Pro content (Fig.…”

The drop in SP recorded by plants with no Si can be associated to the improvement in Pro levels in plants under stress conditions, resulting from a destruction or decrease in the biosynthesis of proteins, which can affect membrane stability, according to Putras et al (2012) in Musa sp. studies.…”

The protective effect of silicon (Si) against environmental stress has been observed in many crops. The objective of this work was to evaluate the impact of SiK® (potassium silicate) fertilization on the resilience capacity of chestnut plants growing under high air temperature conditions and their recovery capacity after a turnover to adequate temperatures. Castanea sativa plants were supplied with 0 mM, 5 mM, 7.5 mM, and 10 mM SiK® and exposed sequentially to 25°C, 32°C, and 25°C for 1 month each. Data suggested that silicon are involved in increasing the heat tolerance of chestnut plants by reducing the oxidative damage and improving the antioxidant enzymes and metabolites. Under heat stress (32°C), there was an increase in the catalase, ascorbate peroxidase, and peroxidase activities, as well as in the phenol content of supplemented plants, which consequently reduced the electrolyte leakage, lipid peroxidation, and hydrogen peroxide content. Additionally, a lower proline content was measured inside the leaves' tissues of Si-treated plants. Besides the resilience against heat stress, after exposure to 32°C, the recovery was also quick.

“…Pengaplikasian boron dan silikon dapat digunakan sebagai alternatif untuk mengurangi dampak negatif cekaman kekeringan dan pemanasan terhadap pertumbuhan tanaman. Aplikasi B pada tanaman yang tercekam temperatur tinggi dan kekeringan memberikan pengaruh positif terhadap kekuatan dan stabilitas sel (Putra et al, 2011). Selain itu B dapat menstimulasi sintesis beberapa jenis antioksidan yang berperan untuk menghilangkan pengaruh ROS sehingga dapat menurunkan kerusakan oksidatif (Rodriguez et al, 2010).…”

Rendahnya produktivitas dan upaya perbaikan peningkatan produktivitas dimasa mendatang dihadapkan pada berbagai kendala, teknis maupun non teknis. Kendala non teknis yang dialami oleh petani akhir-akhir ini adalah perubahan iklim global. Salah satu penyebab terjadinya perubahan iklim adalah pemanasan global oleh efek gas rumah kaca. Salah satu tanaman yang terkena dampak perubahan iklim adalah kelapa sawit.
