ABSTRACT: Banana is an important fruit in China. Banana production played important
role in economic development in tropical region. Banana production in China was
always cut because of lodging caused by typhoon. Getting new cultivars with
high resistance to lodging is the basic resolution to resolve this problem.
Screening and identifying the germ plasm resource is the first step to breed
new cultivars. Banana plant height was high. A single banana plant needs large
area. It is difficult to screen the germ plasm resource by identifying the
physical strength of banana pseudostem. This research focused on studying the
relationship between pseudostem and plant height, pseudostem diameter, acid
soluble lignin, acid insoluble lignin, total lignin, pore numbers of pseudostem
cross section, and the expression of 4-coumarate:CoA ligase (4CL). Results
showed that the plant with high physical strength in seedling stage always has
high physical strength in mature stage. The physical strength of banana
seedling pseudostem was closely related to pseudostem diameter and total
lignin. Pseudostem diameter and total lignin can be used to predict the
physical strength of mature banana pseudostem. Work
on identifying and screening the physical strength of banana germ plasm
pseudostem can be reduced by measuring seedling pseudostem diameter and total
lignin in pseudostem of banana germplasm.
