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.

    PRIMING PHYSIOLOGY AND ITS IMPLICATION ON SEED GERMINATION IN Podophyllum hexandrum Royle
    (UHF,NAUNI,SOLAN, 2017) THAKUR, DINESH; THAKUR, ANJU
    ABSTRACT The present investigation entitled “Priming physiology and its implication on seed germination in Podophyllum hexandrum Royle” was conducted in the Plant Physiology laboratory of Basic Sciences, Dr. Y.S. Parmar university of Horticulture and Forestry, Nauni Solan (H.P.) during 2014-16. The objectives of the study were to induce early, high and synchronized seed germination through priming and to understand the physiological and biochemical basis of priming. The seeds of Podophyllum hexandrum were subjected to seventeen priming treatments and stored thereafter, for 0, 1and 2 months. The minimum number of days taken for onset of germination (19.67 days) was observed in seeds primed with GA3 100 ppm for 48 hours followed by 2 months storage as compared to the control (26.33 days). Maximum germination percentage (68.38 %) was observed with hydroprimng for 72 hrs + 2 months storage, which was closely followed by brassinolide 1.0 ppm for 48 hours + 2 months storage (60.89 %), brassinolide 0.5 ppm for 72 hours + 2 months storage (60.78 %), brassinolide 1.0 ppm for 48 hours + 2 months storage (56.67 %), brassinolide 0.5 ppm for 72 hours + 2 months storage (52.22 %), hydropriming for 24 hours + 2 months storage (47.56 %), KNO3 1 % for 48 hours + 2 months storage (43.07 %), GA3 100 ppm for 48 hours + 2 months storage (40.41 %) and KNO3 1 % for 72 hours + 1 month storage (40 %) respectively as compared to the control i.e. 32.48, 32.29 and 35.89 % for 0, 1 and 2 months storage respectively. Higher germination in above treatments was coupled with shorter mean germination time, higher mobilization efficiency, higher seedling vigour indices and higher enzyme activities. The patterns of changes in physio-biochemical parameters viz. alpha-amylase, dehydrogenase, peroxidase, catalase, total proteins, total amino acids, total sugars, reducing sugars and phenol content were found to be closely related with germination and vigour, reflecting the underlying physio-biochemical changes in seeds subjected to priming treatments. Henceforth, it is concluded that above seed treatments can pave the way for improving germination and vigour of P.hexandrum which otherwise show late, low and asynchronized germination.
