TL;DR: Characters for partial resistance to mildew derived from primitive barley lines were tested and found to have been transmitted to F9 progeny of crosses with the susceptible cultivar Golden Promise with varying degrees of efficiency, and putative transgressive segregation was observed.
Abstract: Characters for partial resistance to mildew (Erysiphe graminis f.sp. hordei) derived from primitive barley lines were tested and found to have been transmitted to F9 progeny of crosses with the susceptible cultivar Golden Promise with varying degrees of efficiency, and putative transgressive segregation was observed. Derived sterol extracts from mildew cell walls were used, in conjunction with infection frequency data, to quantify the mildew present, and this sterol was characterized as being of MW 470, probably (3.beta)-ergosta-5,24(28)dienol (C31.H54.0.SI SILANE).

Journal ArticleDOI
TL;DR: This article measured the leaf temperature and stomatal conductance of seedlings grown in the shade characteristic at ground level in tropical rain forest, following the simulated formation of a large canopy gap over the seedlings.
Abstract: This paper represents an attempt to gather more precise information about the initial responses of seedlings of a dipterocarp species grown in deep shade to a dramatic increase in insolation. This was done by measuring the leaf temperature and stomatal conductance of seedlings grown in the shade characteristic at ground level in tropical rain forest, following the simulated formation of a large canopy gap over the seedlings
