Study On Essential Nutrient And Agronomic Parameters Of Wheatgrass, Plant And Seed

In this study,145 varieties of wheat were chosen as the experimental materials. The physicochemical indexes including contents of chlorophyll and vitamin C in wheatgrass juice; the agronomic traits of wheat plant such as tiller number, plant height, thousand seed weight, panicle length, grain number per spike, seed color, panicle type; physicochemical indexes of wheat seed including protein content and starch content, correlation analysis on these indexes and traits were conducted. It was found wheat cultivars that most from Huang-Huai area, some areas of Southwest as well as middle and downstream region of the Yellow River and foreign country were with high contents of chlorophyll and vitamin C indicating the fitness to produce the wheatgrass juice, chlorophyll content in the range of 3.89-4.28 mg/100g and vitamin C content in the range of 0.57-0.64 mg/100g. Moreover, positive correlations between chlorophyll content and vitamin C content was found with R2=0.83. For the wheat plant and seed, the above cultivars as the resource of wheatgrass juice were characterized by the following average values:tiller number in the range of 4-9, with an average of 6; height number in the range of 64.5-89.1 cm, with an average of 77.6 cm; spike length in the range of 7.5-12.9 cm, with an average of 9.2 cm; grain number in the range of 25-63 pieces, with an average of 38 pieces; grain weight in the range of 38.7-46.7 g, with an average of 39.7 g; protein content in the range of 11.6-14.7 g/100g, with an average of 13.2 g/100g; starch content in the range of 56.2-61.8 g/100g, with an average of 58.6 g/100g. The result suggested that Huang-Huai area, some areas of Southwest as well as middle and downstream region of the Yellow River were fitted to plant the wheat cultivars for producing the wheatgrass juice.
