 * Hence, in the case of the brown leaf we observe the botanical equivalent of metal corrosion. Lower Surface. There is no nitrogen, but more oxygen than on the  upper surface. The leaves were picked up off the ground and although dried in  storage and UHV, the results for the lower surface, with its more numerous  stomata, may reflect its ability to retain water. Brown leaves show a definite  cessation of these processes. It may be reasonable to compare the surface of the  brown leaf to that ...

 * The Diseases Of the three rust diseases of wheat, the most common is called leaf or brown rust. It occurs on the leaf blades, although leaf sheaths can also be  infected under favorable conditions, high inoculum densities, and extremely  susceptible cultivars. It frequently lacks the abundant teliospore production of  stem rust at the end of the season, resulting in a brown leaf lesion rather than a  black stem lesion that occurs with stem rust. When leaf rust teliospores are  produced, they ...

 * The major sources of nitrogen oxides and hydrocarbons (the precursors of ozone ) are combustion engines and industrial plants. Ozone concentrations are highly variable from year to year, season to season, day to day, and throughout the day.  Concentrations of ozone up to 10 pphm have been recorded in New York State.  Five pphm is a potentially toxic level to sensitive plants. Our first experiments  were designed to determine if ozone is a cause of the brown leaf disorder of ...

 * Nitrogen, phosphorus, and potassium increased yield and dollar acre value of the tobacco, with the 120-100-180 treatment of N, P205, and K20 appearing to be  superior to the other treatments evaluated. The effects of the ... Potassium slightly  increased the A and C leaf groups with a corresponding decrease in the X and B  leaf groups, decreased the fine leaf with a corresponding increase in the good  leaf, and increased the brown leaf with a corresponding decrease in the dark leaf.
