Relationship between specific leaf area and the leaf biomass of different diameters as well as the relationship between leaf area index and leaf biomass were examined.

In order to improve per unit area yield and the economic effect of Erigeron breviscapus,adopt double-factor randomized complete to research dynamic change of biological quantity of leaf and sprout of Erigeron breviscapus under different plant quantity and plant space,finding out the best cultivate way that it makes the most biological quantity of photosynthetic organ which can make photosynthesis.

Morphological indexes such as stem diameter, plant height, petiole length in upper, middle and lower parts of cassava were measured and their relationship with the stem and leaf biomass were analyzed.

This study was conducted to assess the impact of leaf age on nutrition,biomass of leaf layer,content of chlorophyll and variety of leaf shape in tetraploid Robinia pseudoacacia.

A concept and model of the camouflage structural model of foliar blade biomimicry were introduced for the first time,which was on the analyses and experimental verifications of the characteristics and influencing factors of green plant.

This article has analyzed and studied the change rule of total sulfur content and chlorophyll content, which is from the mensuration of five vary plant's leaves in difference monitoring spots in the campus of East China Geological Institute.
