Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    STUDIES ON MORPHOHISTOLOGICAL AND PHYSICO-CHEMICAL EVALUATION OF SOME Swertia spp.
    (UHF,NAUNI,SOLAN, 2011) MEHTA, ARUNA; RANA, R.C.
    ABSTRACT The present investigation entitled studies on “Morphohistological and physicochemical evaluation of some Swertia spp.,” was carried out in the department of the forest products, Dr. Y. S. Parmar university of Horticulture and Forestry, Nauni, Solan, (H. P) during 2008-2010. The study was carried out under four experiments on five Swertia species viz. S. chirayita, S. alata, S. angustifolia, S. cordata and S. purpurascens. Excepting S. chirayita which was procured from the university farm at shilly, the remaining four species were collected from their natural habitats from the district of Shimla and Solan. In 1st experiment i.e. “Morphological and histological studies”, morphological features of the five species were recorded for plant height, number of side branches, number of prominent veins, type of leaf, stem and inflorescence. S. cordata and S. purpurascens were pentamerous species with five sepals and petals whereas S. chirayita, S. alata and S. angustifolia were tetramerous with four sepals and four petals each. Both tetramerous and pentamerous species showed bicarpellary syncarpous ovary. Swertia chirayita was differentiated from other tetramerous and pentamerous species on the basis of the two nectar glands present at the base of each petal whereas the other species showed single nectar gland only. Among histological parameters stomatal index, stomatal size (length and breadth), trichome types, T. S. of stem and V. S of leaf were studied. The shape of epidermal cells was observed to be strongly wavy in S. angustifolia and S. purpurascens and mildly wavy in S. cordata whereas, in S. chirayita and S. alata it was angular. Both unicellular as well as multicellular trichomes were observed in all the species. The type of stomata offered a good distinction as S. chirayita was found to have anisocytic type of stomata whereas all the other species showed anomocytic type only. Stomatal index ranged from 31.98±0.42 in S. angustifolia to 18.69±0.20 in S. cordata. Amphiphloic siphonostele was present in all five Swertia species. Cellular inclusions were present in S. chirayita and S. angustifolia only. Endodermis was quite distinct in S. chirayita than other species. In 2nd experiment i.e. “Thin layer chromatographic profile of extract of some Swertia species in different solvent systems. TLC of methanol extract found effective in differentiating S. chirayita from other species due to presence of amarogentin only in S. chirayita. In 3rd experiment i.e. physico-chemical evaluation, the plants of five Swertia species were analyzed for their physicochemical values viz. total ash, acid insoluble ash, sulphated ash, alcohol soluble extractives and water soluble extractive. Total ash was found maximum in S. cordata (5.81%) and minimum in S. purpurascens (4.00%). Acid insoluble ash contents for all the five Swertia species was observed minimum (0. 51%) in S. alata and the maximum in S. cordata (0.94%). Sulphated ash was found maximum in S. chirayita (7.78%) and minimum in S. purpurascens (5.24%). Alcohol soluble extractives were found minimum in S. purpurascens (15.20%) and maximum in S. angustifolia (22.03%).Water soluble extractives were found minimum in S. purpurascens (18.20%) and maximum in S. angustifolia (24.40%). The 4th experiment i.e. “studies on the stability of bitter compounds of Swertia chirayita in different solvent systems”, in this experiment pure amarogentin compound was stored in methanol, methanol:water mixtures (75:25, 50:50. 25:75) and water. The result showed maximum decrease in amarogentin content in methanol:water mixtures which reduced from original value to 18.35-27.81%

    STUDIES ON DOMESTICATION OF Withania somnifera (L.) DUNAL UNDER MID HILL CONDITIONS
    (2016) MEHTA, ARUNA; RAINA, RAVINDER
    ABSTRACT The present investigation entitled “Studies on domestication of Withania somnifera (L.) Dunal under mid hill conditions” was carried out in the experimental field and Laboratory of the Department of Forest Products, College of Forestry, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2011-2015. In the first experiment “Morphological and yield studies” accessions with annual as well as perennial habit were observed. All the investigated accessions showed differences in lamina shape w.r.t basal, middle and terminal leaf and grouped into five lamina shape classes based on observed ovate, broadly ovate, obovate, elliptic and ovate-elliptic lamina shape. Wavy as well as entire margined leaves were present in all the accessions. Maximum plant height (59.87cm) and forking point height (38.15cm) was observed in UHF Local and AGB-040 respectively. Maximum dry root yield (1726.67 Kg/ha) was observed in AGB-004 accession however, maximum main root length (20cm), root diameter (0.94cm) and collar diameter (0.48cm) was observed in AGB-002. S2 season (sowing in March 2014 and harvesting in November 2014) excelled over the S1 season (sowing in July 2013 harvesting in December 2013) in terms of higher root yield. Maximum withaferin-A content (0.075% in S1 and 0.050% in S2) was obtained in accession JA-134 while maximum withanolide-A content (0.081% in S1 and 0.192% in S2) was obtained in UHF Local and AGB-004 respectively. Maximum 12-deoxywitastramonolide content (0.019% in S1 and 0.037% in S2) was observed in AGB-025 and JA-20 respectively. In the second experiment “Floral biology” No inter-accessions difference in floral characteristics was noticed amongst the thirteen accessions evaluated and the type of dichogamy present in its flower was protogynous. Pollen to ovule ratio ranged from 617.73 (AGB-040) to 717.39 (HWS-08-14). Red as well as yellow coloured fruit was present.T6 was observed to be early flowering (98 days) as well as early maturity type (147 days) while accession T10 being the last (155 days and 222 days respectively). Maximum filament (1.77mm) and style length (3.28mm) was observed in JA-100 and AWS-2B respectively. S2 season (sowing in March 2014 and harvesting in November 2014 excelled over the S1 season (sowing in July 2013 and harvesting in December 2013) in terms of higher seed yield kg/ha however, maximum seed yield (1039.21kg/ha) was obtained in AGB-003. In the third experiment “seed germination studies” maximum germination percentage (92.67%), mean daily germination (2.18), maximum peak germination value (3.16), maximum germination energy index (0.64) and shorter germination duration (18.33 days) was observed in JA134. Hydroprimed seeds (seeds soaked for 24 hrs in distilled water before sowing) had higher germination percentage as compared to non-hydroprimed seeds. In fourth experiment “chromosomal studies” all the accessions constituted a single cytotype (n=24; 2n=48) with normal meiosis and high pollen stainability (80.14 to 88.74%). In fifth Experiment “Pollination studies” the breeding system operating in this species appeared to be mixed mating type with both self-pollination and out-crossing contributing. The species appears to be about 34% cross and 66% self pollination under mix mating system of pollination.
