Effect of Pre-sowing Seed Treatments and Synthetic Polymer Coating on Seed Quality and Storability in Redgram (Cajanus cajan. L.)

Successful agriculture depends on high-quality seed, which is a fundamental and important ingredient. Under unfavourable environmental conditions like drought, pre-sowing seed treatment such as seed coating and seed priming could boost the seed germination and seedling vigour. The coating agents often include plant growth regulators, micro-fertilizers, pesticides, and insecticides. The present investigation was carried out to assess the impact of seed treatment and polymer coating on seed quality parameters of pigeon pea cv PRG 176 during 2018 to 2021 at Seed Research and Technology Centre, Rajendranagar, Hyderabad. The trail was laid out in randomized block design with four replications. Freshly harvested redgram variety Ujwala Seeds were treated for Seed hardening with ZnSO4 @100ppm + Seed coating with Polymer 3ml/kg + Bavistin 2g/kg + Imidacloprid 1ml/kg + Pseudomonas fluorescens 10 g/kg + Rhizobium in different combinations. The treated seeds were shade dried, packed in gunny bags, and stored at room temperature to assess the impact of various treatments on seed quality metrics under ambient storage conditions. The results of bimonthly observations on seed quality parameters showed that there were substantial differences between the treatments for the characters under study. The T7 treatment recorded highest germination percentage (98 and 70.67), speed of emergence (12.1 and 10.1), electrical conductivity (0.169 and 0.292), seedling shoot length (14.9 and 8.65cm), seedling root length (14.5 and 8.52cm), seedling length (29.4 and 17.17cm), seedling fresh weight (5.55 and 2.5g), seedling dry weight (0.40 and 0.21g), seed vigour index-I (2881 and 1213), seed Vigour Index-II (53.9 and 14.84) over other treatments under study at initiation of studies (2MAS) and at 28 months of storage period respectively. The current study's findings showed that T7 treatment greatly outperformed all other treatments for all characters, maintaining an optimal germination percentage (70.67%) even up to 28 months of storage under ambient storage conditions.

Effect of Pre-sowing Seed Treatments on Physiological Potential of Seed Germination in Okra

Aims: The present investigation was carried out at SKUAST-Kashmir during the year 2020 to improve the seed vigour and germination potential of okra through pre-sowing seed treatments.
 Study Design: The experiment was laid in completely randomized design (CRD) with three replications
 Place and Duration of Study: The present investigation was carried out at the division of Basic Sciences and Humanities, SKUAST-Kashmir during the year 2020
 Methodology: There were nine pre-sowing seed treatments comprised of simple seed soaking and seed priming with water (T1 and T5), -1.0MPa solution of PEG (T2 and T6), 100ppm solution of GA3 (T3 and T7) and 1.5% solution of KH2PO4 (T4 and T8), respectively along with untreated control (T0). Fifty seeds of each treatment were cultured in 14.0cm Petri dishes lined with 10 layers of moist filter paper. Observations on various germination parameters were recorded at (25±2°C).
 Results: Findings of the study revealed that seed soaking in water (T1) resulted in maximum FGP (93.3%) and GI (16.29) compared to other treatments. Discrete middling of different soaking (AvS) and priming (AvP) treatments indicated the novelty of seed priming over simple soaking. However, unlike FGP and GI, all other parameters viz., CVG, MGT, MGR, T50 and Z-index were found superior when seeds were primed in water (T5) with their recorded values of 87.34%day-1, 1.15day-1, 0.614 day-1, 1.18 day, 0.790, respectively. Values of CVG, MGR and Z index with respect to separate means of simple seed soaking, AvS (69.5%day-1, 0. 0.566day-1 and 0.53) and priming, AvP (75.6%day-1, 0.573day-1 and 0.63) further confirmed the dominancy of seed priming technique over simple seed soaking. Pearson correlation coefficient analysis revealed strong relationship between different quantities of seed germination attributes.
 Conclusion: Seed priming resulted in better germination attributes in okra compared to tradirional seed soaking and as such priming treatments should be practiced instead of traditional seed soaking in okra.

Integrated Effect of Pre-Sowing Seed Treatment, Sowing Windows and Seasons on Seed Yield and Quality of Greengram

An experiment was conducted to study the effect of presowing seed treatment, sowing windows and seasons on seed yield and quality of greengram by sowing the treated seeds on two dates each in summer and kharif. The treatments viz., 8 hours of water soaking; priming with 100 ppm MnSO4, 1% neem leaf extract, 5 ppm GA3, 1% KCl; coating with 10 ml linseed oil, 50 gm rhizobium, 4 g Trichoderma per kg seed; combination of neem leaf extract priming and rhizobium coating, combination of linseed oil and rhizobium coating. Seed quality and yield was highly influenced by seed treatments, dates and seasons; treatment and seasonal effects being greater than sowing dates. GA3, KCl and MnSO4 primed seed found most effective for enhancing the seed quality and yield. Summer season was better than kharif season for both seed quality and yield

The Effects of Seed Treatment with Melatonin on Germination and Emergence Performance of Pepper Seeds under Chilling Stress

Melatonin was first isolated from bovine pineal gland more than half a century ago as an important animal hormone and since then it was proved to be present in almost all forms of life including eukaryotic unicells, prokaryotes, fungi, algae, animals and plants. In this study, the effects of pre-sowing seed treatment with melatonin on germination and emergence performance of pepper seeds under chilling conditions were investigated. Seeds were immersed in 0, 1, 5, 10 or 25 µM melatonin solutions for 24 hours after which they were dried for one day and subjected to germination and emergence tests at optimum and chilling stress conditions. Exogenous melatonin treatment promoted pepper seed germination and emergence under chilling conditions. Treatment of seeds with melatonin especially in 1 or 5 µM concentrations significantly improved germination and emergence percentage and rate whereas dry seeds and seeds treated with 0 µM melatonin exhibited the lowest germination and emergence performance. Melatonin application also reduced the MDA and H 2 O 2 content and elevated SOD and CAT enzyme activity. The improvement in germination and emergence performance of pepper under chilling stress conditions following melatonin treatment may therefore be due to reduced lipid peroxidation and elevated activities of antioxidant enzymes.

The Effect of Pre-sowing Seed Treatment with Metal Nanoparticles on the Formation of the Defensive Reaction of Wheat Seedlings Infected with the Eyespot Causal Agent.

The paper presents research data of lipid peroxidation and lectin activity in wheat seedlings at seed treatment with solution of metal nanoparticles (Zn, Ag, Fe, Mn, Cu) and sole solution of copper nanoparticles under the high pathogen infection background of Pseudocercosporella herpotrichoides (Fron) Deighton (synonym: Oculimacula yallundae (Wallwork & Sponer) Crous & W. Gams). It was shown that investigated nonionic colloidal solutions of biogenic metals have the antioxidant effect through the inhibition of the synthesis of lipid peroxidation products. The increase of lectin activity levels during the early plants ontogenesis stages was observed in wheat seedlings infected with pathogen pre-treated with the mixture of metal nanoparticles.
