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 and biochemical studies in mothbean [Vigna aconitifolia (Jacq.) Marechal] genotypes under soil moisture stress
    (CCSHAU, 2005) Sunil Kumar; Sharma, K.D.
    The study entitled “Physiological and biochemical studies in mothbean [Vigna aconitifolia (Jacq.) Marechal] genotypes under soil moisture stress” was conducted during Kharif season of 2004 at crop physiology research area of Agronomy Department CCS Haryana Agricultural University, Hisar. The experiment was laid out in factorial RBD with four replications. The treatment consisted of two environments of moisture stress (water stress and irrigated control) and four genotypes viz. RMO 40, RMO 257, MB 99-1 and CZM 10. Water stress decreased the maturity duration and profile moisture content consistently. Genotype RMO 40 was shortest in maturity duration and CZM 10 used maximum water. Development of moisture stress enhanced the phonological development significantly. Growth of mothbean in terms of plant height, dry matter accumulation, LAI, LAD, CGR, SLA, and RGR decreased with increase in moisture stress. However, root depth and SLW increased under moisture stress. All Plant water status parameters i.e. w, s, RWC and CTD decreased from morning to afternoon and with moisture stress. Gaseous exchange studies i.e. rate of photosynthesis, transpiration and stomatal conductance get reduced under water stress. Genotype MB 99-1 maintained higher biomass, plant water status and gaseous exchange under moisture stress. Biochemical metabolites i.e. chlorophyll, starch and protein content declined under water stress. However, free proline, total soluble carbohydrates, and free amino acids content showed sharp rise under moisture stress. Seed and biological yield reduced significantly by decreasing yield attributing characters i.e. number of effective pods, seeds per pod and test weight under water stress. Genotype MB 99-1 recorded highest seed yield and observed most drought tolerant in terms of having higher plant water status; gaseous exchange and biochemical metabolites.

    Effect of chromium toxicity and its possible amelioration by putrescine in cauliflower (Brassica oleracea var. Botrytis)
    (CCSHAU, 2006) Madaan, Sukham; Siddiqui, Saleem
    The present investigations were conducted on cauliflower (Brassica oleracea var Botrytis) to study the accumulation of Cr in different plant parts and to evaluated the causes of Cr toxicity in relation to antioxidant defence mechanism and its possible amelioration by putrescine. In the first experiment plants were grown in dune sand treated with 0, 75 and 150 mM K2Cr2O7. Cr caused significant but variable decline in fresh weight, dry weight and calcium content of all the plant parts though it accumulated mainly in roots. No flowering was observed with Cr treatments. In second experiment the ameliorative effect of Purtrescine on oxidative metabolism in chromium treated cauliflower plant was studied. Cr increased the lipid peroxidation level. Decrease in protein and reduced glutathione content was also observed with the Cr treatment. The toxic effect of Cr was more severe at 200 mM. Putrescine was more effective in ameliorating the deleterious effects of Cr at lower concentration on plant growth, total soluble protein, lipid peroxidation. Among the antioxidant enzymes, putrescine had more positive effect on SOD enzyme and isoenzymes in Cr treated plants. However, putrescine also increased the activity of APX, GR and CAT enzyme and isoenzymes.

    Starch metabolism and end use quality of durum wheat in response to high temperature stress
    (CCSHAU, 2007) Bansal, Kavita; Munjal, Renu
    The present experimentation was carried out on durum wheat to study the physiological and biochemical basis of high temperature induced changes in sucrose to starch conversion. Effect of high temperature stress was determined on grain quality and starch metabolism in two durum wheat varieties WH 896 and WH 912. The investigation involved pot studies under screen house conditions during the year 2005-06. In this study, high temperature was induced by shifting the pots to polyhouse after heading. Heat degree days (HDD) were used to quantity the magnitude of heat stress to which these two durum wheat varieties were exposed during the second half of crop growth i.e. from days of heading (DOH) to days of physiological maturity (DOPM) and it is expressed as sum of daily mean temperature during particular period of crop growth. High temperature decreased functioning of various physiological parameters of the plants such as chlorophyll, chlorophyll fluorescence, chlorophyll stability index, membrane thermostability, osmotic potential and dry matter accumulation in grains. The detrimental effect of high temperature on various grain yield and quality characteristics such as grain shriveling score, grain hardness, grain weight/spike, grain number, test weight (1000-grains weight), β-carotene and total protein were also reflected. However, sedimentation value increased under high temperature treatment. Besides these, biochemical parameters such as total soluble sugars, reducing sugars, non-reducing sugars, protein, sucrose, starch and amylopectin were also reduced under high temperature stress except amylose. The enzymes and metabolites involved in starch biosynthesis also declined under high temperature treatment. Among enzymes, soluble starch synthase activity was reduced maximum as compared to other enzymes activities and among metabolites, ADP-glucose and UDP-glucose reduced maximum than other metabolites under high temperature stress. Results of present experiment show that variety WH 896 is more tolerant to heat stress than WH 912 in manners of various physiological, biochemical and quality characteristics parameters when they were exposed to same degree of high temperature stress
