Stomata Frequency and Size in Different Varieties And Lines of Barley
Abstract This research was conducted in Agriculture Faculty Research Center/ El-Fatah University, Tripoli, Libya during 2006/2007 growing season. The objective was to study some morphological, physiological and anatomical characters associated with grain yield and drought resistance in some varieties and lines of barley developed by crossing and hybridization in Agriculture Research Center in Great Jamahiriya. Statistical analysis of the data showed significant differences between varieties and lines in main spikes length and number of spikes/plant .Moreover the differences between varieties and lines in length of main stem spike, total tiller number /plant and spike number/ plant were significant. Statistical analysis of data also showed that differences between varieties and lines in grain number of main spike, grain number of lateral spike, and mean grain weight /spike were significant. Data also showed that differences between varieties and lines in grain weight of main spike were not significant. However, differences between them in grain weight of lateral spike, and mean grain weight /spike were significant. This data also indicated that that there were significant differences in weight of 100 grains /plant, grain weight/plant and straw. In addition to this, harvest index for this varieties and lines was significantly different, and its value ranged between 59.9% and 70.9%. These results also showed that number of spikes/plant was the main grain yield component (r =0.76 p
