Mathematical analysis of climatic characteristics of planting areas and
biological activity of mulberry branch
Abstract
In this study, mulberry branch from 12 planting areas in China were
collected, and the contents of 12 compositions in these mulberry branch
and their differences in bioactivities were compared. The effects of
climate characteristics (environmental factors) in the planting areas on
the compositions and the bioactivities of mulberry branch were analyzed
by partial least square regression and multiple factor analysis. We
found that the precipitation and temperature difference in the planting
areas were important influencing factors, which could change the content
and ratio of key compositions in mulberry branch, which in turn lead to
differences in bioactivities. Planting environments with smaller
temperature difference will make the anti-apoptotic effect of mulberry
branch more prominent, and adequate irrigation will promote
anti-oxidative effect of mulberry branch. These research results provide
evidence for improving mulberry planting conditions and rational use of
resources from the perspective of mathematical analysis.
