“…There was a little bit of variation in the analyzed data, especially in the levels of total sugars in the endosperm and roots. A possible reason could be that the low vigor of rice seed resulted over time of storage in negative consequences on sugars metabolism and amylase activity (Thobunluepop et al, 2009). Also, it will be interesting to analyze the activity of rice amylases under aluminum toxicity alone or in the combination with the addition of silicon because heavy metals can downregulate hydrolysis ability of amylases during germination (Ahsan et al, 2007;Gautam et al, 2010).…”

Silicon has versatile functions in plant biology, especially in plant defense and tolerance to both biotic and abiotic stressors. In this study, it was investigated if silicon could reduce the toxic effect of aluminum on rice. Aluminum was applied to OM4900 rice seedlings, and then their growth and sugar metabolism were determined. At doses of aluminum chloride of 100 and 200 µM, plant height was significantly enhanced and root elongation was reduced. The accumulation of photosynthetic pigments was tightly correlated with the aluminum concentration showing highest amounts at 400 µM. Sugar levels in roots and endosperm decreased upon aluminum addition. Aluminum toxicity in rice seedlings was relieved by addition of silicon in the form of sodium silicate. In the presence of 200 µM aluminum chloride, the addition of 100 mg/L sodium silicate to the hydroponic solution showed no contribution to plant growth or buildup of photosynthetic pigments. At this concentration, root development was not affected while it was at higher concentrations. Sodium silicate addition did not alter the reduction in sugar levels by aluminum. The presence of 200 µM aluminum chloride with or without sodium silicate in the growing solution significantly decreased silicon content in rice husks.

“…Since the chemical attributes of seeds are relevant for successful seedling establishment [11,12], an exploration of the biochemical changes could better evaluate and predict changes in the quality of seeds stored in deep underground spaces. Biochemical indicators associated with seed quality include proteins and sugars, oxidation-related indicators, and hormones.…”

Understanding the impact of deep underground environment on seed storage is an essential prerequisite for realizing the idea of “deep underground agriculture”. To explain the changes in seed germination performance after deep underground storage, we examined the biochemical properties of envelope-packed canola seeds stored for three different durations (66, 90, and 227 days) in four different depths (0, 240, 690, and 1410 m) of a gold mine. Results showed that deep underground storage duration was the leading cause of biochemical properties changes of canola seed, while storage depth exacerbated such changes. Deep underground environment significantly suppressed seed superoxide dismutase (SOD) and soluble sugar (SS), which could be the main reason for the accelerated loss of seed vigor. The appearance of the “compensatory effect” was mainly attributed to the increase in seed growth hormone and the decrease in abscisic acid (ABA) content. The most significant enhancement in growth hormone content was observed in seeds stored at a depth of 1410 m for 66 days, where indoleacetic acid (IAA), gibberellin (GA), and cytokinin (CTK) increased by 63.37%, 21.77%, and 79.36%, respectively. In this study, short-term deep underground storage could enhance seedling growth, but the recommended storage duration for canola seeds should not be longer than 90 days.

Seed Coating in Direct Seeded Rice: An Innovative and Sustainable Approach to Enhance Grain Yield and Weed Management under Submerged Conditions

Dry direct-seeded rice is an alternative cropping technique that should require less water and labor than the classical method of transplanted-flooded rice. Weed competition is the major biological constraint in this resource-conserving production technique reducing the crop yield by 30–80%. This study evaluated the effects of different seed coating treatments on the performance of dry direct seeded rice under field conditions. The seed coating treatments used were preliminarily optimized under lab conditions. The rice seeds were coated with sodium lauryl sulphate (20:1), calcium peroxide (CaO2) (20:6), alginate (20:6), and plant growth promoting bacteria Bacillus sp. KS-54 (20:6 g:mL) on a dry weight basis. Among treatments, seed coating with CaO2 resulted in higher field emergence (85%) and suppressed the fresh and dry biomass of weeds at 15 and 35 days after sowing which subsequently improved the seedling growth of direct seeded rice followed by other treatments and the control. Rice seeds coated with CaO2 and Bacillus sp. KS-54 were effective at enhancing morphological, yield and yield related attributes as compared to other treatments and the control under field conditions. The better morphological attributes and yield of rice plants raised from seeds coated with CaO2 and Bacillus sp. KS-54 were associated with higher concentrations of reducing sugars and enhanced antioxidant enzymes activities.
