    Oxygen uptake through water during early life of Anabas testudineus (Bloch) (1979)
    Springer
    Hydrobiologia 66 (1979), S. 129-133

    Topics: Biology
    Notes: Abstract The O2 consumption (mg/hr) through water in case of Anabas testudineus during development and growth has been measured and its relationship to body weight or length studied. The logarithmic plot of 02 uptake through water either against body weight or length suggested a statistically significant (P 〉 3.53) two-component curve, the point of intersection being at 11 mg body weight and 1.78 cm body length. These are the theoretical values of weight or length at which the responsibility of supplementing nearly 40% of the total O2 demand through the newly developed air breathing organ falls in the early life of the fish. One of the impelling causes forcing developing fry of Anabas to adopt a bimodal gas exchange machinery seems to be 4 fold increase in the diffusion distance at the gills.

    Nitrate reductase and its relationship to protein and yield characteristic of triticale (1976)
    Springer
    Euphytica 25 (1976), S. 193-199 
    Details
    ISSN: 1573-5060
    Keywords: Triticale ; nitrate reductase activity ; correlation with protein
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The optimum conditions for extraction and assay for nitrate reductase (NRase) activity in triticale were determined. NRase activity was positively correlated with plant height, grain yield and grain protein. The leaf protein, seed set or kernel weight had no significant correlation with the NRase activity. Data indicated an apparent interrelationship between NRase activity, grain protein, plant height and grain yield.

    Amylase activity in triticale, X Triticosecale Wittmack (1978)
    Springer
    Euphytica 27 (1978), S. 19-25 
    Details
    ISSN: 1573-5060
    Keywords: Triticale ; Triticosecale ; amylase

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Amylase activity in leaves and the seed exhibited variations among 12 cultivars of hexaploid triticales and was considerably higher than either octaploid triticale or hexaploid wheat. Amylase activity was influenced by the levels of nitrogen and the maturity stages of the kernel. The bran-free endosperm had much lower amylase activity than the whole meal. The measurement of dry matter, starch, total sugars and reducing sugars during the stages of kernal development indicated significant positive correlation between days after anthesis and amounts of starch and dry matter and negative correlation with total sugars, reducing sugars and amylase activity. However, a lower rate of starch accumulation and higher rate of amylase activity prior to kernel maturity was clearly evident.
