Studies onDiplodiaandDiplodia-like fungi: VII. Criteria for classification

Autor: W. B. Hewitt, R. K. Webster, J. Bolstad

Publikováno v: Hilgardia. 42:451-464

Variation encountered in cultures resulting from single pycnidiospores of representative isolates of the Phaeodidymous: Sphaeropsidales was analyzed. Spore morphology, ornamentation, and size are proposed as the most stable characters for use in futu

The Use of Metalorganics in the Preparation of Semiconductor Materials: VIII . Feasibility Studies of the Growth of Group III ‐Group V Compounds of Boron by MOCVD

Autor: H. M. Manasevit, A. J. Nelson, W. B. Hewitt, A. R. Mason

Publikováno v: Journal of The Electrochemical Society. 136:3070-3076

The MOCVD growth of B-As and B-P films on Si, sapphire, and Si-on-sapphire substrates is described; in this process, trimethylborane (TMB) or triethylborane (TEB) is pyrolyzed in the presence of AsH3 or PH3 in an H2 atmosphere. The procedures employe

Studies onDiplodiaandDiplodia-like fungi: IV. Effects of pH, temperature, light, and vitamins on certain taxonomic characters

Autor: W. B. Hewitt, R. K. Webster, M. M. Satour

Publikováno v: Hilgardia. 41:77-94

Fifteen isolates of Diplodia and Diplodia-like fungi were grown on various synthetic media for study of the effects of pH, temperature, light, and vitamins on growth, sporulation, and stability of morphological characters currently used in identifica

Studies onDiplodiaandDiplodia-like fungi: V. Effects of carbon:nitrogen ratio on growth, pycnidia, and pycnidiospore formation

Autor: W. B. Hewitt, R. K. Webster, M. M. Satour

Publikováno v: Hilgardia. 41:95-105

Isolates of Diplodia natalensis and Botryodiplodia theobromae were grown on synthetic media containing various concentrations of carbohydrate and nitrogen sources in different carbon:nitrogen ratios. Varying the ratio affected pigmentation, pycnidia

Studies onDiplodiaandDiplodia-like fungi: VI. Effects of natural substrates on variability in taxonomic characters

Autor: W. B. Hewitt, R. K. Webster

Publikováno v: Hilgardia. 41:107-121

Isolates representing nine genera and 28 species were cultured on eight natural substrates and two media. The object was to compare the effect of natural substrates on the morphology of characters currently employed to delimit genera and species of t

Studies onDiplodiaandDiplodia-like fungi: I. Effects of carbon sources on certain taxonomic characters and on growth in agar culture

Autor: M. M. Satour, W. B. Hewitt, R. K. Webster

Publikováno v: Hilgardia. 39:601-629

Isolates of Diplodia macrospora, D. natalensis, D. zeae, Botryodiplodia hypodermia, B. theobromae, Physalospora rhodina, Botryosphaeria ribis, and a Sphaeropsis sp. were grown on synthetic agar media supplemented with 23 carbon sources used either si

Studies onDiplodiaandDiplodia-like fungi: II. Effects of nitrogen sources on growth, sporulation, and certain taxonomic characters

Autor: W. B. Hewitt, R. K. Webster, M. M. Satour

Publikováno v: Hilgardia. 39:631-653

Twenty-eight nitrogen sources (20 amino acids, 2 amide derivatives of amino acids, 4 organic nitrogen, and 2 inorganic nitrogen) were used for culture of six isolates of Diplodia natalensis and one isolate each of D. zeae, D. macrospora, Botryodiplod
