LThesisItem Open Access Biochemical composition of a wheat genotype as affected by stages of nitrogen application(CCSHAU, 2007) Hitesh; Shashi MadanThe present investigation was conducted to study the effect of seed rates and stages of nitrogen application. WH-711 wheat variety at three seed rates i.e., 100, 112.5, 125 kg/ ha was sown under four different nitrogen splittings i.e., T1- ½ dose at sowing + ½ dose at CRI (Ist irrigation), T2 – 1/3rd dose at sowing + 2/3rd dose at first node (40-45 days), T3- 1/4th dose at sowing +1/2 at first node + 1/4th dose at anthesis (85-90 days) and T4- 1/3rd dose at sowing (2/3rd dose – 6.9 kg N ) at first node + 6.9 kg N as urea spray (3% ) at post anthesis (95-100 days). Treatment without nitrogen (control) was also included for comparison. Analysis of data revealed that splitting of recommended dose of nitrogen improved the grain quality by increasing the quality parameters viz. hectoliter weight, ß- carotene content, wet, dry gluten content and total protein content. Higher protein content of 12.68% was obtained at highest value of seed rate (125 kg/ha) and split dose of nitrogen T4. However, sedimentation value, starch, amylose content remained unaffected at different seed rates and varying stages of N-application. The nitrogen content and phosphorous content increased while the sulphur content remained unaffected with different seed rates and split dose of N-application. A progressive increase in total sugars, reducing sugars and non-reducing content was also observed at various stages of N-application. The lysine content and true protein content also increased with split dose of N-application; however both these parameters were not affected with different seed rate and various stages of N-application. Among different protein fractions, the albumin and globulin fractions increased with split dose of N while gliadins and glutenins remained unchanged The polypeptide pattern of gliadins and glutenins remained unchanged by different seed rates and stages of N-application. Grain yield was significantly higher at 125 kg/ha and 112.5 kg/ha as compared to 100 kg/ha seed rate. Splitting of recommended dose of N marginally increased the grain yield by 4.1% (43.5 q/ha) than the grain yield obtained (41.7 q/ha) at T1.ThesisItem Open Access Effect of Cd and Cr (VI) on biochemical constituents in oat (Avena sativa L.) during development(CCSHAU, 2005) Tulika; Gupta, KaushalyaAvena sativa L. cv. HJ-8 plants were raised in earthenware pots filled with 5 Kg sand and treated with requisite amounts of Cd (0, 1, 5, 10, 20 and 40 ppm), Cr (VI) (0.1, 0.2, 0.5, 1.0, 2.5 and 5.0 ppm), and Cd:Cr (5:0.1, 5:0.5, 5:1.0, 20:0.1, 20:0.5 and 20:1.0 ppm) respectively in form of CdCl2 and K2Cr2O7. Chlorosis and tip burning started to appear after 10 ppm Cd and 0.5 ppm Cr (VI). At 5 ppm Cr (VI), very reduced plant height and severe chlorosis was observed followed by delayed flowering at 40 ppm Cd and 2.5 ppm Cr (VI) with no inflorescence emergence at 5.0 ppm Cr (VI) application. All the morphological parameters under study showed stimulation at lower doses (upto 5 ppm Cd and 0.5 ppm Cr (VI)) and then inhibited with further rise in heavy metal ion concentration. The fresh weight attained maximum value at 100 DAS and then decreased at maturity. FW and DW also showed a similar trend with increasing heavy metal ion levels. Photosynthetic pigments increased by 40% at 5 ppm Cd and 20% at 0.2 ppm Cr (VI) at 100 DAS and then decreased with increasing levels of Cd and Cr (VI). Chlorophyll b was found to be more sensitive than chlorophyll a under heavy metal toxicity. EC and pH of leaf leachates was found to be similar for all treatments while slight decrease was observed at higher doses. Nitrogen and nitrate nitrogen content was maximum at 5 ppm Cd, 0.1 ppm Cr (VI) and 5:0.1 ppm Cd:Cr combinations. Maximum reduction in Na and K content was observed at 40 ppm Cd, 5 ppm Cr (VI) and 20:1.0 ppm (Cd:Cr) application. However, the stimulation at lower doses was also observed. Crude fibre content was maximum at maturity with maximum reduction of 10% at higher doses of Cd2+ and Cr6+ ions. Sugar content attained maximum value at 100 DAS. Stimulation at lower doses of Cd and Cr was observed for sugar content which was maximum at 5 ppm Cd (43, 25 and 69%), 0.1 ppm Cr (VI) (40,14 and 38%) and Cd:Cr
