    Notes: Summary The rates of CO2 efflux were measured by an alkali absorption method (using 20 ml 0.5 N NaOH) from soils in four undisturbed sites [two evergreen oak forests, Quercus floribunda Lindl. (tilonj oak), Quercus leucotrichophora A Camus (banj oak), and two evergreen conifer forests, Cedrus deodara Loud. (deodar forest) and Pinus roxburghii Sarg. (chir pine forest)] and three disturbed sites. The sites were located between elevations of 1850 and 2360 m in the Central Himalaya. The seasonal pattern of soil respiration was similar in all the sites with a maximum during the rainy season, intermediate rates during the summer season and the lowest level of activity in winter. The rate of CO2 efflux was higher in broadleaf than in conifer forests, and it was lowest in the disturbed sites. Among the edaphic conditions, soil moisture, N, organic C, pH, soil porosity, and root biomass positively affected total soil respiration. The proportion of root respiration to total soil respiration was higher in the disturbed sites than the undisturbed sites in winter. Conditions in the winter season were less favourable for microbial respiration than for root respiration.

    Description / Table of Contents: Riassunto Si è presentata un’analisi del ruolo delle forze non appaiate nella dinamica reticolare di metalli h.c.p. limitati da s.p. rispetto a Mg e Zn. L’energia totale è stata estesa fino al terz’ordine nel potenziale elettrone-ione. La matrice dinamica contiene termini che originano da interazioni del tipo a coppie tra ioni cosiccome contributi dovuti a somme di forze a tre corpi non accoppiati. Tali forze, che derivano dall’inclusione di termini di terz’ordine, sono del tipo a corto raggio e possiedono le caratteristiche di forze tensoriali. Si conclude che l’interazione a tre corpi non appaiata è necessaria per spiegare la dinamica reticolare di metalli h.c.p. Le curve teoriche di dispersione sono confrontate coi dati sperimentali. Si è trovato un buon accordo tra i risultati teorici e sperimentali lungo le direzioni di simmetria.
    Notes: Summary An analysis of the role of the nonpair forces in the lattice dynamics of s.p. bonded h.c.p. metalsviz. Mg and Zn has been presented. The total energy has been extended up to third order in the electron-ion pseudopotential. The dynamical matrix contains the terms arising from central pairwise interactions between the ions as well as contributions due to sums of nonpair three-body forces. Such forces, arising from the inclusion of third-order terms, are of short-range nature and possess the character of tensor forces. It is concluded that the nonpair three-body interaction is necessary for explaining the lattice dynamics of h.c.p. metals. The theoretical dispersion curves are compared with the experimental data. Good agreement is found between the computed and experimental results along the symmetry directions.

    Notes: The objective of this study was to compare the seed yield, seed weight, and maturity of random lines derived from two contrasting populations of common bean (Phaseolus vulgaris L.): Middle American (TR 7790) and Andean × Middle American (TR 7791). TR 7790 involved crosses between common-bean races of Middle American origin only (Mesoamerica and Durango), whereas TR 7791 involved crosses between races of Middle American and Andean origin (Mesoamerica and Nueva Granada). A total of 85 random lines from each of these two double-cross, interracial populations, a bulk sample of both populations, and all parents were evaluated in a replications-in-set design in eight environments in Colombia between 1991 and 1993. The mean yields of parents, population bulk, and lines from TR 7790 were significantly higher (P 〈 0.05) than those of TR 7791. Six lines in TR 7790 and nine lines in TR 7791 yielded significantly higher (P 〈 0.05) than the mean of their parents. Four lines from TR 7790 out-yielded the highest-yielding line from TR 7791. Moreover, while three lines from TR 7790 out-yielded its best parent, none of the lines from TR 7791 out-yielded its highest yielding parent. Thus, substantial yield gains should be expected from interracial populations within the Middle American group of common beans, whereas selection for higher seed yield from Andean × Middle American populations would seem problematic.

    Notes: Two double-cross populations were used to evaluate the efficiency of independent, alternate, and simultaneous selection practiced from the F2 to F8 for resistance to anthracnose and angular leaf spot of common bean (Phaseolus vulgaris L.). Seven resistant and high-yielding lines were selected from each of the four environments used during this study. These lines and the seven parents involved in two populations were evaluated in an 8 × 8 lattice design with three replications in two cropping seasons. Pathogen inoculum was used to create the three test environments: anthracnose alone, angular leaf spot alone, and anthracnose and angular leaf spot together. All entries were also evaluated in a fourth, disease-free environment. Selection for resistance to anthracnose and angular leaf spot was effective in both populations. Mean disease scores of all selected lines for anthracnose were lower than that of angular leaf spot irrespective of selection environment. Among the three stress environments, yields were higher in the anthracnose environment. However, lines selected alternately for anthracnose and angular leaf spot were usually higher yielding, and the highest yielding line in both populations originated from this selection environment. The mean yield of selected lines was higher and the highest yielding line originated from the population involving a parent (G 1805) belonging to the Mexican highland race ‘Jalisco’. Positive association existed between seed yield of protected and pathogen-inoculated environments. No association was found between resistance to anthracnose and angular leaf spot.
