    Changes in Phosphorus Fractions and Phytase Activity of Rice Seeds during Germination (1971)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 25 (1971), S. 0 
    Details

    Topics: Biology
    Notes: The present experiment provides information on the phosphorus compounds in rice seeds and elucidates the changes they undergo during germination. In ungerminated seeds, the bulk of total-P appears in phytin (about 76 per cent). It is then dephosphorylated in course of germination with a simultaneous accumulation of large amounts of inorganic-P. Lipid-P increases very rapidly from 0 to 24 hours. The increase up to 72 hours is gradual, after which it drops at 96 hours and again rises to a maximum after 120 hours. The ester-P and RNA-P, fractions increase in concentration with time of germination (except 120 hours). Protein-P begins to fall after 48 hours, while DNA-P remains more or less constant throughout the experiment.The two pH optima recorded for phytase activity at 4.0 and 9.0, suggests that there exist two phytases, one acidic and the other alkaline. Both behave similarly during germination with a continuous increase throughout the course of the experiment. The enzyme with an optimal pH at 4 hydrolyses phytin more actively than the other with the pH optimum at 9.0. Phytase shows maximum activity at a stage when most of the phytin has disappeared; the metabolic significance is uncertain.

    Rhamnose Bound Indole-3-Acetic Acid in the Floral Parts of Peltophorum ferrugineum (1974)

    Notes: The presence of rhamnose bound indole-3-acetic acid (IAA) was reported from acetone extract of anthers and carpels of the flowers of Peltophorum ferrugineum. Hydrolysis of the sugar ester gave IAA and rhamnose. Identification of IAA was based on physical measurements supported by bioassay. Bound and free IAA were not detected in petals, seeds and seed coats.

    Metabolic Changes in Developing Rice Seeds (1971)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 24 (1971), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Metabolic changes in developing rice seeds were studied with respect to respiration, carbohydrate and nitrogen fractions, nucleic acids and hydrolytic enzymes, viz. α-amylase, adenosine triphosphatase (ATPase) and phytase. — Respiration rate was maximum after 12 days from the date of pollination and became feeble afterwards with the fall in the moisture content of the maturing seeds. In the early stage, there was a preponderance of reducing sugars which were replaced later by nonreducing forms. Dry matter accumulation was mainly due to the steady rise in starch content. There was a gradual accumulation of protein nitrogen throughout the experiment, the rate being highest between 12–16 days. RNA content increased steadily till the seeds became mature, while DNA formed rapidly during the first 20 days and was maintained at the same level thereafter. —α-Amylase activity increased up to 20 days and declined sharply afterwards. The peak activities of ATPase and phytase were recorded at 32 and 24 days after pollination, respectively.

    Lead content of indian tea (1973)

    Notes: Summary A random survey was conducted to determine lead content in Indian tea and its decoctions. Lead content of various samples of tea was found to be between 0.4 to 1.6 ppm and in decoctions it was between 0. 002–0. 012 mg/liter. The effect of temperature and pH was also studied and it was found that larger amount of lead was leached out in the decoctions at low pH and at high temperature.

    Studies on lead extraction from glazed pottery under different conditions (1973)

    Notes: Summary An investigation was carried out to estimate the amount of lead extracted by storing acetic acid in 231 pieces of glazed earthenware pottery. The average concentration of lead was found to be 4.2 mg/litre and the range was 1.0 to 6.5 mg/litre. The amount of lead extracted increased sharply between 70° to 90°C. Hence storage of hot beverages in pottery for long periods may pose health hazards due to chronic lead toxicity.

    Formation of very thin oxide films on copper: Kinetics and mechanism (1970)

    Oxidation of metals 2 (1970), S. 349-360

    Notes: Abstract A detailed fundamental investigation of the oxidation of copper in the very thin film range at temperatures below 60°C has been carried out. The results have been analyzed on the basis of Mott and Cabrera's theory of oxidation. Most of the earlier workers have tried to fit in the data in the integrated form of the equation which necessarily involves imposition of certain boundary conditions and assumptions which are not always justified. Hence in the present work, an attempt has been made to fit the data in the inverse logarithmic equation, using the differential form itself, thereby eliminating all the boundary conditions. The accuracy of the procedure used has been checked by back calculation and plotting the theoretical curve with the superimposed experimental points. The different parameters in the equation have been calculated and are found to be in excellent agreement with the theoretical values, thereby supporting Mott's equation quantitatively. The change in rate with temperature has been interpreted as due to the change in the energy of solution of the metal ion in the oxide.
