Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    In vitro morphogenesis of Polygonatum verticillatum (L.) all along with comparative study of biological activities of rhizomes collected from different altitudes of Uttarakhand

    Medicinal plants are the valuable and harmless source of drugs that have drawn the attention of many scientists and pharmaceutical companies for the preparation of many natural products. Polygonatum verticillatum (L.) All., an Asparagaceae family member, medicinal herb of North West Himalaya. It is also a member of Astavarga group of medicinal plants that have high medicinal value in Ayurveda. Regeneration of this plant through seeds is slow process as the seeds have double dormancy. So the present study is carried out for the rapid propagation of these medicinal plants through the tissue culture. Maximum per cent callus induction was found in MS medium supplemented with TDZ (0.5 mg L-1) and 2, 4 –D (1.0 mg L-1). Maximum per cent (81.25 ± 3.6) shoot induction was achieved in MS fortified with mT (0.5 mg L-1) with maximum (23.67 ± 2.02) no. of shoots/explant. Maximum per cent (71.33 ± 8.3) root induction was observed in MS medium supplemented with IBA (1.0 mg L-1) and maximum no. of roots/explants (10.33 ± 0.6) was found in MS medium fortified with NAA (1.0 mg L-1) + Kn (0.5 mg L-1). Maximum per cent embryo induction (62.5 ± 7.2) was achieved in MS containing Kn (2.0 mg L-1) + NAA (1.0 mg L-1). Synthetic seeds were prepared in 2.5 % sodium alginate and 2 % CaCl2. In the present study, the effect of altitudes on the antioxidant activity, Total flavonoid content and total phenol content was also evaluated in aqueous and methanol extracts of rhizomes of P. verticillatum collected from different altitudinal regions. The rhizomes were collected from Chamoli (P1), Bhowali (P2), Jageshwar (P3), Munsiyari (P4). Maximum extraction yield (%) was achieved in P4 (14.78 %) and P4 population (12.43 %) in aqueous and methanol extract respectively. Majority of phytochemicals were present in aqueous and methanol extract except tannins and alkaloids were absent in aqueous solvent. DPPH scavenging activity (%) was maximum in P4 (38.34) and P3 (32.368) in aqueous and methanol extract respectively. Comparatively lower IC50 (μg/ml) values of DPPH were obtained in P4 population (172.17) in aqueous and P3 popualtion (183.71) in methanol extract. Maximum FRAP (μg BHT/mg) activity was observed in P3 (77.21) and P4 population (36.69) in aqueous and methanol extract respectively. Total antioxidant activity (μg VCE/mg) was highest in P4 population (23.35) in aqueous extract and P3 population (16.87) in methanol extract respectively. Maximum flavonoid content (μg QE/mg) was achieved in P3 population (17.67) in aqueous extract and P4 population (24.17) in methanol extract respectively. Highest total phenol content was achieved in P4 population (35.76) and P4 popualtion (23.83) in aqueous and methanol extracts respectively. The GC-MS analysis of aqueous and methanol extracts of P. verticillatum rhizome showed the presence of 27 and 30 bioactive compounds respectively. In aqueous extract 7-Nonenamide (22.19%), 5- Hydromethylfufural (8.87 %), 3-Furaldehyde (8.82 %), 5-Hydromethylfurfural (8.87%), D- Alanine, Npropargyloxycarbony - isohexyl, ester (7.20 %),2,4- Dihydroxy-2,5-dimethyl-3(2H)- furan-3-one (5.76 %), 2-acetyl – 1-pyrroline (5.40 %), 3- Amino-2- oxazolidinone (4.39 %), 1,3 –Dioxolane, 2,4,5- trimethyl- (3.77 %) were reported as main compounds were the major compounds while in methanol extract 4-Hexene-3-one, 4, 5 – dimethyl (40.60 %), furfural (26.07), (R) – (-) – Methyl -2- butane (4.20 %), Cholesterol (3.06%), 10, 11, 12, 13, 14, 15, 16, 17-tetradecahydro-1H-cyclop enta [a]phenanthren-3-ol (2.86 %), 26-Nor-5-cholesten-3á-ol-25- one (2.47 %) were the major compounds were the major compounds. Utilizing the findings of the present research not only provides a method for mass propagation of the species but also helps in assessing the phytochemical differences in the populations growing at different altitudes.
