ThesisItem Open Access SEED SOURCE VARIATION IN TREE MORPHOLOGY AND OIL QUALITY OF Prunus armeniaca L.(UHF,NAUNI, 2023-09-19) SWATI; HP SANKHYANABSTRACT The present study entitled “Seed source variation in tree morphology and oil quality of Prunus armeniaca L.” aimed to assess the variation in genotypes of wild apricot for different morphological traits and oil quality attributes along the altitudinal gradient. A total of 45 healthy and phenotypically superior genotypes of wild apricot were selected from nine sites in Kinnaur District and Spiti Valley of Himachal Pradesh during the years 2021-2023. The findings of the study revealed that significant variations were observed for morphological traits, fruit characters and oil parameters among genotypes, sites and altitudinal zones. Site-wise analysis of pooled data showed that S1(Nichar) was accounted for as having maximum values for leaf width, leaf area, petiole length and stone weight (for stone weight value was at par with S5). S2 (Katgaon) was recorded to have the highest pulp-stone ratio and volume of fruit traits. S3 (Chagaon) was noted to have the maximum values for leaf length, fruit length, fruit breadth, fruit eight, pulp weight, and specific gravity. S4 (Kanai) had the largest flower size. S6 (Pooh) was identified to have the greatest values for kernel length and kernel breadth. S7 (Chango) had maximum100 kernel weight and was on par with S6 for kernel breadth. 100 seed (stone) was observed maximum at S8 (Poh). Among the three zones A1(2000-2500 m) was found best for traits like leaf length, leaf width, leaf area, petiole length, fruit length, fruit breadth, fruit weight, pulp weight, stone weight, pulp: stone, volume and 100 kernel weight whereas A2 (2500–3000 m) had maximum values for flower size (flower length and flower breadth) and Kernel length. A3 (3000–3500 m) exhibited higher values for Specific gravity of fruits, 100 seed (stone) weight, and kernel breadth. The highest mean values for oil content percentage, Specific gravity, and Refractive index were recorded in Altitudinal zones A3 (45.60%), A2 and A3 (0.914667) and A2 (1.4726) respectively. Altitudinal zone A3 was observed to have maximum values for all the chemical characteristics of oil, i.e., Acid value (2.54), Saponification value (190.80), and unsaponifiable matter (0.80%). Further, these superior genotypes could be used to raise progenies with desired attributes and deoiled cakes for cow feed, potentially creating new opportunities in the industry and increasing a farmer's or grower's total revenue.ThesisItem Open Access STUDIES ON SEED PELLETING AND DIRECT SOWING IN ONION (Allium cepa L.)(UHF,NAUNI, 2017-09) SWATI; THAKUR, ASHOK K.ABSTRACT The present investigation entitled ‘Studies on Seed Pelleting and Direct Sowing in Onion (Allium cepa L.)’ was carried out in two experiments at experimental farm and laboratory of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan, HP during 2015-17. The seeds of onion cv. Nasik Red were pelleted with clay, Vitex leaf powder + clay, darek leaf powder + clay, ZnSO4 + clay, KNO3 + clay, KH2PO4+ clay, Bavistin + clay, Contaf + clay, Redomil + clay, keeping unpelleted seed as control. The first experiment was conducted to study the effect of seed pelleting on seed quality during storage. The pelleted seeds were stored at ambient conditions for 12 months in the plastic boxes. The seed quality was tested at four months interval i.e. immediately after treatment (i.e. zero month), four months, eight months and twelve months storage. Highest germination (81.19%), seedling length (9.64 cm), seedling dry weight (19.43 mg), seedling vigour index-I (753.19), seedling vigour index- II (1475.53) and speed of germination (28.20) were observed in onion seeds pelleted with ZnSO4 + clay. Among the storage periods, fresh pelleted seed (0 month) showed maximum values with respect to germination (93.20%), seedling length (11.91 cm), seedling dry weight (22.12 mg), seedling vigour index- I (1079.99), seedling vigour index- II (2047.01) and speed of germination (32.65). The germination (93.20%), seedling length (11.91cm) and seedling vigour index- I (1079.99) were highest in the fresh seeds (0 month) pelleted with the ZnSO4 + clay powder. The unpelleted seed showed minimum germination (75.00%), seedling length (8.88 cm) and seedling vigour index- I (654.89) after 12 month of storage. Germination and vigour of seeds pelleted with ZnSO4 + clay powder @ 300g + 4700 g seeds decreased with increase in storage time, however, the rate of deterioration of pelleted seeds was lower than the unpelleted control. The second experiment was conducted in the field using the pelleted seeds and crop was evaluated for bulb crop parameters. The seeds pelleted with ZnSO4 + clay showed maximum values w.r.t. plant height at 60 days after transplanting (DAT) (45.98 cm), average leaf length (37.19 cm), number of leaves per plant (9.10), polar diameter (41.44 mm), equatorial diameter (57.31 mm), bulb size index (2340.24 mm2), neck thickness (12.12 mm), average bulb weight (74.00 g), bulb yield (6.42 kg per plot or 385.04 q per ha), plant height before neck fall stage (54.78 cm). From the present studies, it can be concluded that onion seeds pelleted with ZnSO4 + clay powder @ 300g + 4700 g per kg seed showed significant effects for enhancing quality, growth and yield.ThesisItem Open Access STUDIES ON THE PHARMACOKINETICS OF CEFTRIAXONE IN SHEEP(AAU, Anand, 2004) SWATI; Thaker, A. M.Ceftriaxone, a third generation semisynthetic cephalosporin is resistant to various types of β-lactamases, with potent activity against aerobic gram negative and gram positive bacteria. The present study was designed to investigate pharmacokinetics of ceftriaxone in sheep following single dose intravenous and intramuscular administration at the dose rate of 10 mg kg-1 of body weight. Following administration of drug the blood samples were collected at predetermined tiftie intervals. Drug concentration in plasma was determined using High Performance Liquid Chromatography (HPLC). Following intravenous administration, the plasma concentration-time curve was characteristic of a two compartment open model whereas, it was best described as one compartment open model with first order absorption after intramuscular administration. Based on the plasma drug concentration time curve various rate constants and pharmacokinetic parameters were calculated by least square regression analysis. Following intravenous administration the mean plasma ceftriaxone level of 104.56 ± 3.69 µg ml-1 was observed at 0.033 h (2 minutes), which rapidly declined to 17.82 ± 1.13 µg ml-1 at 0.5 h (30 minutes). The concentration of ceftriaxone >= 0.48 µgml-1 of plasma, well above the MIC was maintained up to 6 h after administration of drug. The distribution half-life (t1/2α) and elimination half-life (t1/2β) were 0.13 ± 0.01 h and 1.21 ± 0.05 h, respectively. The mean values of apparent volume of distribution [Vd(area)] and volume of distribution of drug at steady-state (Vdss) were calculated to be 0.41 ± 0.02 and 0.27 ± 0.01 L kg-1 respectively. The mean value of total body clearance (CIB) was 3.91 ± 0.13 ml min-1 kg-1ThesisItem Open Access “Transcriptomic analysis through Denovo assembly, Mapping and Annotation for Identification of Salinity Stress Tolerant Genes in Rice (Oryza sativa)”(SARDARVALLABH BHAI PATEL UNIVERSITY OF AGRICULTURE MEERUT 250110, 2020) SWATI; Sirohi, Dr. Aniland identification of the genes conferring tolerance to salt stresses and map out signaling pathways and ultimately utilize this information for improving the salinity stress conditions in salinity susceptible rice variety IR-64.
