Study on the Characteristics of Two New Varieties of Pseudostellariae Radix from Xuanzhou
To explore the planting conditions and character advantages of two new varieties of pseudostellariae radix"Xuanshen No.2"and"Xuanshen No.3"in the natural and soil environment of Xuancheng area,with"Xuanshen No.1"as the control,the field comparison experi-ment was conducted between two new varieties of pseudostellariae radix and wild pseudostellariae radix to compare the emergence and falling-down of the new varieties,branch number,leaf length,stem and leaf width,leaf shape,leaf color and other botanical traits,seed index such as number of roots per plant,root length,root thickness,yield,stress resistance,etc.The comprehensive agronomic traits of the two new varieties in the field were evaluated.The results showed that the two new varieties were strong in growth,compact in plant type,moderate in plant height,and strong in high-temperature resistance.The incidence of leaf spot and virus disease was less in the middle and late stages of growth,and the yield of"Xuanshen 2"was 82.58% higher than that of CK,and the drying rate was 31% .The yield increase of"Xuanshen No.3"was 14.27%,and the drying rate was 33% .The two new varieties have excellent comprehensive characteristics and are suitable for planting in Xuanzhou Dis-trict.At the same time,they provide the theoretical basis for spreading planting in large areas.
