Crop performance and climatic records were collated for high production counties in South Dakota to evaluate the effects of temperature and precipitation on yields. The crops involved were corn, soybeans, sorghum, oats, spring wheat, and winter wheat. Records were compared for the period from 1965 to 1982. The computer data file for each county includes seven climatic parameters, dates of plant development, adjusted yield-and yield rank by year. The crop/climate record for the 17-year period was evaluated in sixteen counties per crop each year. Thus, 272 county x year observations were made for each crop, except for soybeans which involved …

Ultrastructure Of Wheat (Triticum Aestivum) Leaf Cells Infected With Leaf Rust (Puccinia Recondita), And Wheat Streak Mosaic Virus, Saleh H. Shrief
Electronic Theses and Dissertations
Puccinia recondita ultrastructure resembles that of other rust species. The urediospore infection was characterized by the formation of a specialized structure, the haustorium, within the leaf cells. The haustorium contains organelles such as nuclei, mitochondria, microbodies, ribosomes, lipid bodies, and vacuoles. A haustorial neck connects the haustorium with the haustorial mother cell, and contains a neck band made up of darkly stained material. The neck band was located at the last one third of its length toward the haustorium. The haustorial mother cell was situated intercellularly, and closely adhering to the cell wall, but contained few organelles, and the nucleus …
