Abstract


The experiment Rumex several forage species and eco - biology, physiology and production characteristics were studied . The results show that Rumex between different species , there are significant differences between different ecotypes hybrid dock - Rumex K-1 has the obvious advantage of the growth , mainly in the longer growing period , grain weight and higher leaf area higher biomass yield , the index is higher than its parent of the Tianshan sorrel and different ecotypes of the female parent . Physiological characteristics of the study results show that the hybrid dock - Rumex K-1 has significant physiological advantages, mainly in the higher photosynthetic rate, chlorophyll content , tissue water content , for high yield and quality of the production performance of laying a physiological basis . Rumex forage plants Isozyme Polymorphisms Rumex plant species , ecotype , there are obvious differences between the polymorphism organs with similar findings . The isozyme technique can be used as an effective method of identification of species , ecological , and varieties . Isozyme similar findings , the the hybrid sorrel - Rumex K - 1 Xinjiang acquisition Pakistan days sorrel ( 4901 ) and Tianshan the sorrel ( 4903 ) at the discretion of the co-workers of the peroxidase enzyme spectrum with higher similarity Xinjiang collected the bar days sorrel (49O3) in esterase isoenzymes have greater similarity ; small similarity the Pakistan days sorrel with Hover ancient collection efficiency . Rumex isoenzyme activity in parts of the measurement results and related sub- fold results showed that the more exuberant growth , its isoenzyme activity super above the underground , a period of growth and development of general aboveground activity of peroxidase activity is higher than esterase activity.
