Proline is considered endogenous regulator that alleviates environmental stresses as water stress. This study investigated the effect of seed priming with proline on summer squash plant to mitigate water stress. Four squash cultivars were used SQ250, Behera, Sp 11/4 and Kaha5/7. The seed priming were hydro-priming (as a control) and priming seeds that primed with 20 mmol proline for 24 hours. The study was conducted in greenhouse where the squash plants were subjected to three irrigation levels (100% FC (Field capacity), 75% FC and 60% FC) in three replicates. The results revealed that water stress significantly decreased all measured physiological parameters (plant height, number of leaves, dry weights, fresh weights, fruit weights and relative chlophyll content index), while proline contents in plants increased with water stress Meanwhile seed priming with proline significantly ameliorate squash tolerance to water stress through improve these parameters. Sp11/4 and Kaha5/7 gave the highest fruit weights so they are the recommended squash cultivars that can be used under water stressed condition after seed priming with proline.

“…Seed priming has many advantages as accelerate germination through increase enzymes activities (Varier et al, 2010). Also is shorting emergency time by 28% even in stress conditions (Qamar et al, 2022). Primed seeds have higher antioxidant defense that increase plant tolerant to different environmental stresses .…”

Sustainable agriculture, essential for global food security, calls for innovative methods to improve crop yields and conserve resources. Nanopriming, utilizing nanoparticles to enhance seed germination and growth, builds preresistance to diseases and reduces dependence on pesticides and fertilizers. Here, we address two major challenges in the field: effects of varying nanoparticle sizes on seed nutrient enhancement and the lack of efficient, automated systems for germination monitoring. Focusing on zinc oxide (ZnO) nanoparticles, we synthesize them using hydrothermal and solvothermal methods. Our experiments on bitter gourd (Momordica charantia) and red amaranth (Amaranthus gangeticus) show that nanopriming with these particles, especially those smaller than 30 nm, significantly improves seed germination and seedling growth. Specifically, we observe up to a 23% increase in germination and a 40% rise in shoot length for bitter gourd and a 43% increase in germination with a 20% boost in shoot length for red amaranth. Nanopriming at a concentration of 150 mg/L significantly enhances bitter gourd plant growth, with a notable 90% increase in height and 74% increase in leaf count compared to hydroprimed plants, showcasing the positive impact on fresh biomass production. For field-level monitoring, we propose a sophisticated smart monitoring system incorporating a custom-designed two-axis CNC machine with a single-board computer and high-resolution camera to redefine seed germination and growth assessment.

“…Increasing crop yields, improving crop quality, and enhancing crop resistance through chemical control technologies are some of the key agronomic measures in modern agricultural planting technology systems ( Wang, 2019 ; Zhang et al., 2021 ; Cheng et al., 2020 ). Plant growth regulators are widely used in crop production to improve plant architecture, increase the photosynthetic rate, enhance root function, improve resistance to stress, increase yield, and improve quality ( Zhao & Wang, 2012 ; Huang et al., 2021 ; Qamar et al., 2022 ; Dhaka et al., 2022 ).…”

Effects of exogenous auxin on yield in foxtail millet (Setaria italica L.) when applied at the grain-filling stage

et al. 2023

Foxtail millet (Setaria italica L.) is of high nutritious value, which is an important crop in arid and semi-arid regions. The objective of this experiment was to explore the effects of the synthetic auxin naphthalene acetic acid (NAA) on the physiological processes of foxtail millet, and to provide a theoretical basis and technical approaches for its efficient use in millet cultivation. Two foxtail millet varieties (‘Jingu 21’ and ‘Zhangzagu 5’) were treated with six concentrations of NAA from 0-144 mg L-1 at the grain-filling stage in field experiments. The photosynthetic pigment contents, gas exchange parameters, chlorophyll fluorescence parameters, and grain yield were measured in foxtail millet. The results showed that low concentrations of NAA (18-36 mg L-1) increased the contents of photosynthetic pigments, and increased the activities of antioxidant enzymes, the photosynthetic rate, and the activity of photosystem system II (PS II). At higher NAA concentrations, the facilitation effect of the treatments diminished, showing a clear concentration effect. In this study, yield was significantly and positively correlated with PS II effective quantum yield (Y(II)) and the PSII electron transport rate (ETR), and the net photosynthetic rate (Pn) was significantly and positively correlated with chlorophyll content, stomatal conductance (Gs), Y(II), and ETR. These results also indicated that exogenous NAA application promotes the production of ATP and NADPH by increasing the efficiency of electron transfer within the photosystems and also improved photochemical utilization, which facilitates the fixation and reduction of carbon, ultimately leading to an increase in Pn and increasing grain yield in foxtail millet.
