STUDY ON THE ROOT ARCHITECTURE OF CESPITOSE PLANTS IN THE GRASSLAND OF INNER MONGOLIA
Scanning the root of 33 Bunch type plants by WinRHIZO 2009 root analysis system root architecture of cespitose plants,data were analyzed.The results showed that:1.Roots gross area and root furcation number are the key factors influencing the root architecture of cespitose plants; 2.Among the root parameters of cespitose plants in the grassland,the total root length has great correlation significance with total root surface area/root tip numbers and furcation numbers ; root total surface area has great correlation significance with root tips number/furcation number and avcrage diameters; total root volume has great correlation significance with total surface area and average diameters ; root tip number has great correlation significance with furcation numbers.3.The main factors influencing root architecture are relatively stable for the plants with specific root architectures.
