Abstract A description is provided for Isthmiella faullii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Apparently confined to Abies balsamea. DISEASE: Causes a needle blight of Abies balsamea. According to Darker (1932), it 'is the commonest and most destructive of the Hypodermataceae on Abies balsamea in eastern North America'. It is particularly damaging to seedlings and juvenile plants. In northern Ontario, from where the disease was originally identified, infection occurs during the summer, but signs of the disease do not appear until the following spring, when needles become brown and conidiomata develop, conidia being discharged in July, and shortly after this ascomata begin to form, maturing in July of the following year. GEOGRAPHICAL DISTRIBUTION: Reported from Canada: Nova Scotia, Ontario, Quebec and USA: Michigan and New Hampshire. TRANSMISSION: Through air dispersal of ascospores, which directly infect the leaves (Darker, 1932).

Thermal dependence of the enzymes SOD, CAT, and POD was investigated in leaves of Iris pumila plants inhabiting two contrasting light environments, a sun-exposed dune site and a woodland understory. At the same assay temperature, both the specific activity and the activation energy of SOD and CAT were higher in plants inhabiting vegetation shade than in those experiencing full sunlight. Conversely, the temperature optima for the two enzymes did not differ between alternative radiation environments. The specific activity of POD increased with temperature increase, and was always greater in plants growing under full sunlight than in those from vegetation shade. The activation energy of POD was higher than that of SOD or CAT, being lower in sun-than in shade-exposed plants.

Three near isolines of soybean [Glycine max (L.) Merr.], glabrous, normal, and dense, were examined by light, scanning electron, and transmission electron microscopy, as well as by energy dispersive x-ray spectroscopy. This was done in order to determine the morphology and possible functions, in addition to conveying insect resistance, of their non-glandular trichomes.The uppermost fully expanded trifoliate leaf from greenhouse grown juvenile plants was chosen for examination. Fixed tissue was examined by LM, TEM and SEM as previously described. Some tissue was prepared for energy dispersive spectrometry by fixing in glutaraldehyde but omitting osmium. The tissue was then dehydrated, critical point dried, and coated with carbon. Si x-ray maps were made on the adaxial and abaxial leaf surfaces of all three biotypes.LMs of Spurr embedded toluidine blue stained semithin sections of normal (Fig. 1) and glabrous (Fig. 2) trichomes appear similar in structure.
