    Notes: Wild relatives are a potential source of genetic diversity to lentil (Lens culinaris Medik). The objective of this research was to obtain viable interspecific hybrids between the domesticated lentil and its wild relatives.The paper details the results of a number of interspecific crosses among L. culinaris, L. orientalis, L. odemensis, L. ervoides and L. nigricans. Viable hybrids were produced between L. culinaris × L. orientalis, L. culinaris × L. nigricans, L. culinaris × L. ervoides and between L. culinaris × L. odemensis. Further viable hybrids were obtained between L. culinaris and L. ervoides, which have the potential to be a ‘bridge’ in hybridization to L. culinaris for specific L. nicrigans lines which proved recalcitrant in L. culinaris × L. nigricans crosses. This is the first time that four wild species of lentils have been used successfully in hybridization with cultivated lentils, and viable hybrids produced. This paper also suggests that the artificial supplement of GA3, hormone is needed after fertilization for the normal growth of the hybrid embryo, possibly as the natural GA3 production is restricted with alien pollinations in cultivated lentils in both F1 and backcross hybrids.

    Changes in fatty acid profile during larval development of freshwater prawn Macrobrachium rosenbergii (de Man) (1999)

    Notes: The fatty acid profile of Macrobrachium rosenbergii (de Man) larvae grown under hatchery conditions was studied during development from larval stage I to IX. The larvae were reared under a ‘modified static green water’ system with a modification in which the tanks were not seeded by green water at the beginning of culture period. Feeding with newly hatched Artemia nauplii started at stage II with five or six Artemia per larva, which was then gradually increased to 60 organisms per larva at stage IX when the study was terminated. In general, fatty acid composition changed during larval development, with the greatest variations observed from stage I to stage III. Monounsaturated fatty acids constituted the major moiety of fatty acids of stage I whereas polyunsaturated fatty acids were the dominant fatty acid class in later developmental stages. Moreover, polyunsaturated fatty acids were dominated by n-6 series in stage I and by n-3 series for the rest of the larval stages. The major fatty acids of the stage I larvae were palmitic (16:0), oleic/vaccenic (18:1) and linoleic (18:2n-6) acids, whereas for the rest of the larval stages, palmitic (16:0), stearic (18:0), oleic/vaccenic (18:1), linolenic (18:3n-3) and eicosapentaenoic (20:5n-3) acids were the prominent fatty acids. Although decreases in total saturated fatty acids and monounsaturated fatty acids were observed, polyunsaturated fatty acids tended to increase during larval development. Unlike penaeid larvae, M. rosenbergii larvae appeared to have sufficient capability to convert palmitic (16:0) acid to stearic (18:0) acid. Moreover, dietary linoleic (18:2n-6) and linolenic (18:3n-3) acids appeared to be converted to arachidonic (20:4n-6) and eicosapentaenoic (20:5n-3) acids to meet larval demand for such highly unsaturated fatty acids respectively.

    Notes: Abstract The effects of Glomus mosseae and Paecilomyces lilacinus on Meloidogyne javanica of tomato were tested in a greenhouse experiment. Chicken layer manure was used as a carrier substrate for the inoculum of P. lilacinus. The following parameters were used: gall index, average number of galls per root system, plant height, shoot and root weights. Inoculation of tomato plants with G. mosseae did not markedly increase the growth of infected plants with M. javanica. Inoculation of plants with G. mosseae and P. lilacinus together or separately resulted in similar shoots and plant heights. The highest root development was achieved when mycorrhizal plants were inoculated with P. lilacinus to control root-knot nematode. Inoculation of tomato plants with G. mosseae suppressed gall index and the average number of galls per root system by 52% and 66%, respectively, compared with seedlings inoculated with M. javanica alone. Biological control with both G. mosseae and P. lilacinus together or separately in the presence of layer manure completely inhibited root infection with M. javanica. Mycorrhizal colonization was not affected by the layer manure treatment or by root inoculation with P. lilacinus. Addition of layer manure had a beneficial effect on plant growth and reduced M. javanica infection.

    Mass production of Glomus mosseae spores (1995)

    Topics: Biology
    Notes: Abstract  Five crops inoculated with Glomus mosseae were grown for 10 weeks and the development of mycorrhizal infection and sporulation were assessed. Infected roots from pot cultures of different ages were used to examine the host effect on the development of mycorrhizae. The effectiveness of each host was assessed by measuring spore numbers. For all hosts, the percentage of root length infected increased rapidly up to 10 weeks after sowing. Infectivity of root inocula increased with increasing percentage of root length infected with the inoculum for all crops, except where large numbers of mature spores (1755) had been produced on barley. The highest spore numbers were achieved in the rhizosphere of barley plants, followed by chickpea and beans. The lowest spore numbers were found in the rhizosphere of corn and okra plants. The type of the crop as well as the harvest date greatly influenced the size of the spore population and the extent of root colonization of G. mosseae.

    Notes: Abstract The effects of 15N-labelled ammonium nitrate, urea and ammonium sulphate on yield and uptake of labelled and unlabelled N by wheat (Triticum aestivum L. cv. Mexi-Pak-65) were studied in a field experiment. The dry matter and N yields were significantly increased with fertilizer N application compared to those from unfertilized soil. The wheat crop used 64.0–74.8%, 61.5–64.7% and 61.7–63.4% of the N from ammonium nitrate, urea and ammonium sulphate, respectively. The fertilizer N uptake showed that ammonium nitrate was a more available source of N for wheat than urea and ammonium sulphate. The effective use of fertilizer N (ratio of fertilizer N in grain to fertilizer N in whole plant) was statistically similar for the three N fertilizers. The application of fertilizer N increased the uptake of unlabelled soil N by wheat, a result attributed to a positive added N interaction, which varied with the method of application of fertilizer N. Ammonium nitrate, urea and ammonium sulphate gave 59.3%, 42.8% and 26.3% more added N interaction, respectively, when applied by the broadcast/worked-in method than with band placement. A highly significant correlation between soil N and grain yield, dry matter and added N interaction showed that soil N was more important than fertilizer N in wheat production. A values were not significantly correlated with added N interaction (r=0.719). The observed added N interaction may have been the result of pool substitution, whereby added labelled fertilizer N stood proxy for unlabelled soil N.

    Notes: Abstract The effect of annealing on the electrical properties and the refractive index of red mercuric iodide (HgI2) single crystals is investigated. The ac-impedance and phase angle were measured in the frequency range from 100 Hz to 10 kHz at different annealing temperatures. The ac-conductivity, dielectric constants, loss tangent and the refractive index as a function of frequency are determined. The results are discussed in terms of structural changes taking place as a result of the heat treatment of the HgI2 single crystals.
