Patterns in tropical grass silicification: response to substrate fertilization

摘要：

Silica is accumulated mostly in grasses.The effect of soil properties has not been much documented.Proportions of silica in plants decreased on raising the soil pH and concentration in soil decrease with higher value of pH ( Jones & Handreck 1965).There is a quantitative relationship between silica concentration in the soil solution and the amount taken up by plants.We explore the hypothesis that soil fertility ( N‐P‐K) influences leaf silicification of tropical fodder grass species.The response of plant silica concentration to substrate fertilization in 5 grass species was examined, as well as silica relationships with leaf structural parameters tightly correlated with leaf functioning.
