The Effect Of Yield And Quality Traits Treated With Different Varieties And Cultivation In Fagopyrum Esculentum Moench

Took 12 varieties of Fagopyrum esculentum Moench as experimental material, Used grey correlation analysis method, Explored the influence on production of different varieties of F. esculentum Moench and under the condition of cultivation measures agronomic traits and physi-biochemical traits of primary and secondary relations. The following are experimental results.1. The agronomic traits and yield correlation importance degree of different varieties F.esculentum Moench is following:Seed setting rate (0.8666), Grain number per plan (0.8221). Plant height (0.7720), Stem diameter (0.7140)、Grain (0.7004)、Flovvering (0.6975), Dry weight (0.6243). The biochemical and physiological traits and yield correlation degree is:Chlorophyll SPAD (0.7171), Malondialdehyde (MDA) conic-(0.7035), Proline (Pro)content(0.6372), Peroxidase (POD)activity (0.6369), Superoxi dismutase (SOD) activity (0.6191) and Catalase (CAT) activity (0.6028)2. Irrigation treatment in Growth Period compared with before planting in F. esculent Moench, the seedling stage, budding stage, full-bloom stage can significantly improve soil moisture content of experimental plot can significantly improve the plant height diameter and the dry matter weight (Stem, weight and total dry weight), The impact on, esculentum Moench effective primary branch number is not obvious; Higher (600 times. 300 times)the concentration of humic acid treatment can significantly improve the p height, stem diameter, The dry matter weight (Stem weight and total dry weight) and effective level of branch number.3. Under the condition of Irrigation before sowing, medium concentration of humic treatment can significantly improve the leaf chlorophyll content and photosynthetic rate of esculentum Moench, Intercellular CO2 concentration of leaves was significantly reduced; chlorophyll content and photosynthetic rate were positively correlated, and negatively correlated with intercellular CO2 concentration.4. Under the condition of Irrigation before sowing, medium concentration of humic treatment can significantly improve the SOD activity. POD activity and Pro content-Significantly reduce the MDA content of the blade. Different moisture content and CAT activity of humic acid treatment of F. esculentum Moench leaves effect is not obvious.5. Irrigation treatment in Growth-Period-Treatment can significantly increase the tot number of flowering F. esculenlum Moench. Different moisture and humic acid treatment had a little effects on F. esculentum Moench grains per spike. Irrigation under the condition of the soil before sowing medium concentration of humic acid treatment can significantly improve the grain number per plant, Seed setting rate and yield. F. esculentum Moench yield and seed setting rate were highly positive correlation and negatively correlation with the total number of flowering.6. Under the condition of Irrigation before sowing, Medium concentration of humic acid treatment can significantly improve the F esculentum Moench grain starch and protein content. Higher concentration of humic acid treatment can significantly improve the crude fat content of F. esculentum Moench kernels. Rent moisture and humic acid content of total flavonoids of F. esculentum Moench grain cellulose and three kinds of free radical (hydroxyl free radicals, DPPH and superoxide anion free radical) removal ability effect is not obvious.7. Under the condition of different cultivation measures, Agronomic characters and yield of Fesculentum Moench correlation from big to small in this is:Grain number per plant (0.9034), grain (0.7835), effective number of primary branches (0.7614), seed setting rate (0.7535), total number of flowering (0.6230), stem diameter (0.6189), dry weight (0.6138), Plant height (0.5027). The physi-biochemical characters and yield of Fesculentum Moench correlation from big to small in this is:Photosynthetic rate(0.9428), Chlorophyll SPAD value (0.9402), Pro content (0.8362), SOD activity(0.8272), CAT activity(0.8100), POD activity (0.7531), MDA content (0.7246), intercellular CO2 concentration (0.5703).Results show that:Different varieties of F. esculentum Moench the agronomic index of seed setting rate and grain number per plant and physiological and biochemical indexes of the chlorophyll content and MDA content in the correlation of outputs; Under the condition of different cultivation measures, Agronomic index of per plant and grain number per spike, Physi-biochemical indexes of photosynthetic rate and chlorophyll content and yield of correlation degree is bigger. The grain number per plant and chlorophyll content in different varieties and correlation with yield under the conditions of different cultivation measures are larger, Can be used as common reference index.
