Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Physiological characterization of linseed (Linum usitatissimum L.) genotypes under salinity
    (CCSHAU, Hisar, 2023-10) Manisha; Anita kumari
    The present investigation entitled “Physiological characterization of linseed (Linum usistatissimum L.) genotypes under salinity stress” was investigated in the laboratory of Deptt. Of Botany and Plant Physiology. Salinity is one of the most important factors that restricts plant growth in many regions of the world. In order to assess how salt stress effects germination, growth and some physiological characteristics of flax, two separate experiments were carried out in the laboratory. The first experiment included fifty genotypes and three salinity levels (control, 8dS/m and 10dS/m). The results showed that with increasing salinity, germination percentage, seedling length, seedling fresh and dry weight and seedling vigour index decreased as compared to control. Similarly, the relative water content of shoot and root decreased with increasing salinity level from control to 10dS/m. At 10dS/m salinity level osmotic potential (ψs) of shoot and root also declined. Total chlorophyll content, chlorophyll stability index and total carotenoid content of shoot also decreased from control to 10dS/m salinity level. The level of osmolyte i.e. proline increased with increasing salinity level. A marked increase in hydrogen peroxide (H2O2) and lipid peroxidation (MDA) was noticed in both shoot and root of linseed genotypes. Enzymatic activity of antioxidative enzymes (SOD, CAT, POX, APX and GR) increased under salinity (10 dS m-1) stress. Despite, the increase in the activity of these enzymes ascorbate (AsA) and glutathione content decreased at 10dS/m respective to their control. The above observations suggest that salinity had a negative effect on morpho-physiological and biochemical parameters, ultimately resulting in a decrease in the growth of plants. Overall it is concluded that accession no. IC0268344, IC0499192 performed better under salinity stress so, these accessions may be considered as relatively tolerant.
