The present review article is dealing with the potentiality of micronutrients in terms of seed priming treatment and its effect within the plant system is considered. Since last 3 to 4 decades various scientists are working with different planting methods and introduced several seed invigoration techniques, one of them is seed priming. Seed priming is basically a restricted hydration treatment with appropriate timing, in which seeds are treated with various types of organic and inorganic compounds. Whereas in this review, we have discussed the potential of different micronutrients in seed priming treatments for escalating crop growth, development and grain yield. Micronutrient priming has several beneficial effects in the morpho-physiological, biochemical and molecular aspects of the plants. In most cases, micronutrient application through seed treatment has astonishingly performed better than other application methods. Being an easy and cost effective method of micronutrient application, seed priming offer an attractive option for resource-poor farmers. [ABSTRACT FROM AUTHOR]

3 on late sown sesame crop (Sesamum indicum) var. T-4 (V1 ), T-12 (V2 ) and Shekhar (V3 ) in respect of germination, physiomorphological, biochemical and yield parameters were observed. The treatments comprised of KNO3 [10 mM (T1 ), 15 mM (T2 )] and distilled water (DW) primed sets (T0 ). The results showed that the KNO3 treatment promoted germination percentage, root and shoot length, fresh and dry weights of seedling, catalase, peroxidase and proline content as well as yield attributes like number of capsules plant-1 , number of seeds capsule-1 , test weight (1000 seed weight in g) and yield plant-1 (g). After 80 h, the highest germination percentage was recorded in 15 mM KNO3 (T2 ) primed seeds of Sesamum indicum var. T-4, T-12 and Shekhar. The average of root length, shoot length, fresh weight, and dry weight was recorded highest in treatment T2 in comparison to distilled water primed seeds (control) at 25 DAS in all varieties i.e., T-4, T-12 and Shekhar respectively. Yield attributes like number of capsules plant-1 , number of seeds capsule-1, test weight and yield plant-1 were also highest in treatment T2 in all varieties V1 , V2 and V3 respectively. Variety V1 and treatment T2 recorded the highest values of catalase, peroxidase and proline content followed by variety V3 and V2 and treatment T1 and T0 at 45 DAS respectively. It had been found that seed priming with KNO3 ameliorate the effect of late sowing. [ABSTRACT FROM AUTHOR]- Published

Sulfur is a growth-limiting and secondary macronutrient as well as an indispensable component for several cellular components of crop plants. Over the years various scientists have conducted several experiments on sulfur metabolism based on different aspects of plants. Sulfur metabolism in seeds has immense importance in terms of the different sulfur-containing seed storage proteins, the significance of transporters in seeds, the role of sulfur during the time of seed germination, etc. The present review article is based on an overview of sulfur metabolism in seeds, in respect to source to sink relationships, S transporters present in the seeds, S-regulated seed storage proteins and the importance of sulfur at the time of seed germination. Sulfur is an essential component and a decidable factor for seed yield and the quality of seeds in terms of oil content in oilseeds, storage of qualitative proteins in legumes and has a significant role in carbohydrate metabolism in cereals. In conclusion, a few future perspectives towards a more comprehensive knowledge on S metabolism/mechanism during seed development, storage and germination have also been stated.

An experiment was conducted in both laboratory (germinative attributes) and field conditions (growth attributes) with completely randomized design (CRD) and randomized block design, respectively, to view the responses of different priming treatments in two wheat varieties: HUW-234 (V1) and BHU-3(V2). In the present study, seeds were primed with water (hydro; T2), Mg (NO
3 )2 (T3), ZnSO4 (T4), and a combination of both salts (T5). Their carry over effects were observed on the germinative and vegetative phases of growth. All treatments were compared with the performance of nonprimed control seeds (T1). Maximum germination percentage (98.33, 100%) was noted with T3, whereas length of shoot (8.83, 10.23 cm) and root (9.47, 10.73 cm) and their fresh (0.34, 0.45 g) and dry weights (0.05, 0.07 g) were recorded maximum in T5 for both varieties; however, the vigor index I and II showed varietal difference, but primed sets were found always superior with respect to nonprimed control. Study of plant height, leaf number and area, fresh and dry weights of total leaves and stem showed the best performance under combined use of both salts, i.e., Mg (NO3 )2 and ZnSO4 as priming agents, followed by ZnSO4 , Mg (NO3 )2 , hydro, and the nonprimed one. The study of biochemical parameters such as protein content and nitrate reductase activity of leaves showed the highest increment in combined priming treatment and increased 63.77, 90.37, 37.44% and 12.81, 5.61, 7.75%, respectively, after 35, 45, and 60 days after sowing. It is likely that chlorophyll, nitrogen, iron, and zinc content also followed a similar pattern and were enhanced in combined priming treatments as compared to nonpriming treatment. Therefore, the result suggests that priming seeds with Mg (NO3 )2 and ZnSO4 worked synergistically at varietal level and improved growth attributes at field conditions.

• Heat stress in plants causes several morphological, physiological and molecular changes affecting growth and yield attributes. • Seed priming is an eco-friendly technology to induce uniform and rapid emergence of seed that leads to better stand establishment and improvement in yield, under both optimal and adverse environments. • Nitrate priming of seeds improves seed germination, crop growth, nitrogen metabolism and increases nitrate reductase activity, enabling reversal of heat stress induced responses in plants, maintaining the yield potential of the plants. Exhaustion of natural sources due to expanding usage leads to an increase in global temperature. Heat stress and rising CO 2 severely impact crop growth and catastrophic loss of agriculture ecosystem, productivity and quality. The physiological and metabolic processes of plants are affected by heat stress due to denatured proteins, lipid structure, alteration in membrane integrity and inactivation of enzymes incurred at various growth stages. To diminish heat stress losses in plants, many techniques such as conventional breeding, genetic engineering, molecular breeding were used by the agriculturists, which helped develop tolerant varieties of crops with increased quality and production. Recent advancement in seed priming has many fold impacts such as mitigation of stress via improving tolerance mechanisms in plants, reduction in soil and water pollution, improved production and food quality of important agriculture crops. It is one of the low-cost, reliable and profitable crop improvement techniques. Nitrates have several roles in modulating the plant processes. Priming with nitrate salts improves nitrate reductase and amylase activity, nitrogen, amino acid and chlorophyll content in leaves, causes increase in proline, sugar content, antioxidant metabolism, grain yield, protein and nutrient content in various crops. Despite positive responses of nitrate seed priming, this technology has been less applied in the area of crop production in the field condition. Considering these facts, this review depicts responses of the plants under heat stress and their management through nitrate seed priming. [ABSTRACT FROM AUTHOR]
