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.

    EFFECT OF WATER STRESS AND BRASSINOSTEROID ON GROWTH AND PHYSIO - BIOCHEMICAL CHARACTERISTICS OF APPLE PLANTS
    (UHF,NAUNI, 2017) SUDARSHNA, KUMARI; THAKUR, ANJU
    ABSTRACT The present study entitled “Effect of water stress and brassinosteroid on growth and physio-biochemical characteristics of apple plants” was conducted in the field of the Department of Fruit Science and Plant Physiology laboratory of Basic Sciences, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during January - June 2016. The objective of the experiment was to study the effects of imposed water stress and brassinosteroid on growth and physio-biochemical responses of apple plants. One year old plants of both varieties i.e. Super chief and Red chief were pre-treated by foliar application of brassinosteroid 0.05 and 0.10 ppm, three days before subjecting to stress. Water stress conditions were imposed by withholding watering for 15 and 30 days. Growth characteristics viz. plant height, branch number, leaf area, root length, fresh and dry weight of root and shoot and root-shoot ratio showed significant reduction under water stress. The maximum reduction in growth parameters was registered by plants subjected to 30 of water stress as compared to 15 days of water stress. Physiological indices viz. photosynthesis, chlorophyll fluorescence, canopy temperature depression, transpiration rate, stomatal conductance and water use efficiency showed inhibitions under both water stress durations with maximum reduction under 30 days of water stress than the control for both cultivars. Osmoregulating substances i.e. total free amino acid, total free proline and total soluble sugars showed increased accumulation and enhanced activities of antioxidant enzymes i.e. catalase and peroxidase with increasing duration of water stress which helped in enhancing drought tolerance. However brassinosteroid at both concentrations could help in maintaining vital growth, physiological and biochemical processes under water stress conditions. Foliar spray of brassinosteroid (0.05 ppm) prior to imposition of stress can pave the way to minimize the deleterious effects of water stress on apple plants.
