    Pollen callus culture in Triticum aestivum (1982)
    Springer
    Theoretical and applied genetics 63 (1982), S. 71-73 
    Details
    ISSN: 1432-2242
    Keywords: Triticum aestivum ; Pollen ; Anther culture ; Callus ; Regeneration ; Plantlets
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Pollen shed between 4–8 d from anthers of Triticum aestivum cultured in liquid medium gave rise to calluses. Tillers were harvested at the mid-to late-unicellular pollen stages and chilled for 8 d at 4–5 °C before the anthers were dissected out. Pollen cultures gave about 6 times as many calluses on a per anther basis as anthers cultured on solid medium. With the most productive of 5 cultivars tested, pollen culture results in roughly one callus for each anther used, though the calluses formed by pollen culture were less productive for the regeneration of shoots than calluses derived from anthers cultured on solid medium. The ratio of green to albino shoots is roughly 1∶ 1 for anther cultures but considerably less for pollen cultures.

    ISSN: 1432-2242
    Keywords: Triticum aestivum ; Grainprotein ; Gene action ; Regression ; Diallel cross
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Diallel crosses between five divergent vulgare wheat cultivars were made in order to evaluate the mode of inheritance and combining ability of grain proteins. Significant differences in grain protein content were found between cultivars and their hybrids. It was established that the inheritance of seed protein in the F1 generation included both additive and non-additive gene action.

    Cytogenetic structure of common wheat cultivars from or introduced into Spain (1982)
    Springer
    Theoretical and applied genetics 61 (1982), S. 129-133 
    Details
    ISSN: 1432-2242
    Keywords: Interchange ; Chromosome arrangements ; Common wheat ; Triticum aestivum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Chromosome arrangements of twenty-eight cultivars of common wheat, Triticum aestivum L., from or introduced into Spain are compared with that of ‘Chinese Spring’ taken as a pattern. All the cultivars analyzed differ from ‘Chinese Spring’ by one or two reciprocal translocations. When 12 out of 28 cultivars were compared it was concluded that a minimum number of thirteen interchanges are present, involving at least ten different chromosomes of the complement. The interest of a reappraisal of the rôle of interchanges in the evolution of Gramineae is pointed out.

    Effects of waterlogging on young wheat plants (Triticum aestivum L.) and on soil solutes at different soil temperatures (1982)
    Springer
    Plant and soil 69 (1982), S. 311-326 
    Details
    ISSN: 1573-5036
    Keywords: Aeration ; Calcium ; Carbon dioxide ; Ethylene ; Nitrate ; Nitrite ; Nitrous oxide ; Oxygen ; Potassium ; Roots ; Triticum aestivum ; Waterlogging ; Wheat

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary We report a study of the mechanism by which the response of plants to waterlogging can be modified by soil temperature. Wheat was grown initially in well-aerated soil in a controlled environment room before the soil was flooded with aerated, deionized water. The soil temperature was maintained constant in the range 6–18°C while the air temperature was at 14°C. Waterlogging damage was greater in plants at the higher soil temperatures when the plants were compared at the same chronological age. However, when compared at the same growth stage, the response to soil temperature was little differenti.e. plants subjected to waterlogging for a long time at low soil temperatures exhibited a similar reduction in growth and other properties as those subjected briefly at higher temperatures. The concentration of dissolved oxygen in the soil solution declined rapidly at all temperatures, being almost zero after 36 h waterlogging. Temperature affected rates of change of the concentrations of dissolved carbon dioxide, ethylene, nitrous oxide, nitrite, nitrate, calcium and potassium. The importance of soil-and plant-determined properties in the waterlogging response of plants at different temperatures are discussed.

    Selection for yield in small plots of spring wheat (1982)
    Springer
    Euphytica 31 (1982), S. 549-564 
    Details
    ISSN: 1573-5060
    Keywords: Triticum aestivum ; wheat ; grain yield ; selection
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Four selection experiments were sown: single-row plots with single row-spacing (≃20 cm), single-row plots with double row spacing (≃40 cm), three-row plots and six-row plots both with single row-spacing (≃20 cm). Selection entries were mimiced by 16 different varieties or advanced breeding lines, which were also sown in a yield trial. Each experiment was laid out as a 4-times replicated randomized block design. Row length was 2 m. Alley borders and border-rows of multiple-row plots were harvested separately to evaluate the effects of different harvesting procedures on the selection efficiency. Removal of alley borders was found to be disadvantageous, since the gain in precision was more than offset by the loss in sampled area. Wide spacing of single-row plots improved the selection efficiency in comparison with normal spaced single-row plots. In multiple-row plots the selection efficiency was not improved by harvesting only the central rows. For gross plot yield (= yield of net plot + yield of alley borders) the differences in selection efficiency between the various selection plot-types were explained on the basis of the genetic variance, the environmental variance and the coefficient of genetic correlation with ‘farm’ yield as determined in the yield trial.

    Notes: Summary Five highly active N2-fixing strains of Klebsiella isolated from the phyllosphere of tropical plants, KUPBR1, KUPBR2, KUPM, KUP4 and KUP6 along withAzotobacter vinelandii OP,A. chroococcum G40 andDerxia gumnosa were sprayed on the foliage of a high yielding wheat cultivar, Kalyansona. The strains of Klebsiella enhanced dry wt., chrorophyll and nitrogen content, and 1000 grain weight. Grain yield in inoculated plants varied between 19.9 and 25.09 quintals ha−1 against 24.34 quintals with urea. Best results were obtained with KUP4 which when applied at half dose was as effective as 52.5 kg Urea-N ha−1. Azotobacter and Derxia only slightly improved growth and nitrogen content of grain or straw.

    Use ofAzospirillum brasilense as biofertilizer in intensive wheat cropping (1982)
    Springer
    Plant and soil 66 (1982), S. 217-223

    ISSN: 1573-5036
    Keywords: Azospirillum brasilense ; Biofertilizer ; Spring-wheat ; Triticum aestivum ; Winter-wheat
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Three field experiments were conducted on ten cultivars of winterwheat and four cultivars of springwheat to estimate the growth promoting effect ofAzospirillum brasilense under varying nitrogen doses. Independent of cultivar selection or nitrogen dose a highly significant yield increase could be observed in winterwheat: strains S631 and SpBr14 increased the average grain yield with 9.14% and 14.82% respectively. When the yield components were studied a coinciding increase in ear density could be demonstrated of resp. 10.57% and 13.55%. Less significant results were obtained with springwheat although in one experiment strain SpBr14 significantly increased grain yield. As with winterwheat tillering of the plant was markedly affected by inoculation with both strains. In a companion greenhouse experiment it was found that inoculation with Azospirillum can cause a decrease in the root mass of wheatplants except when strain SpBr14 is used. Therefore it is suggested that the presence of a higher tillering together with an undisturbed nutrient uptake capacity can result in yield increases after inoculation withAzospirillum brasilense.

    Keywords: Kaolin spray ; Mulch ; N-application ; Split application ; Triticum aestivum ; Wheat
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Studies revealed that the application of fertilizer nitrogen brought a significant increase in grain and straw yield of wheat. The significant effect was also noticed on such yield contributing characters like number of effective tillers per metre row length, spike length, and number of grains per spike. The increase of nitrogen level from 40 kg/ha to 80 kg/ha also brought a significant increase in yield and yield contributing characters. The application of entire dose of nitrogen at the time of sowing was as good as its split application. The application of nitrogen also influenced the nitrogen concentration of grains whereas, the other treatments did not influence the nitrogen concentration in grains or straw. The nitrogen treatments did not influence the moisture content of soil. The application of mulch or mulch+Kaolin resulted in significantly higher content of soil moisture in 0–15 cm soil depth as compared to control or Kaolin spray alone which was simultaneously reflected in yield and yield contributing characters.
