Effects of parent rock and bamboo age on silicon and phytolith-occluded carbon in the leaves of Moso bamboo
摘要
Abstract
In order to study effect of parent rocks and bamboo ages on the contents of silicon and phytolith occluded organic carbon (PhytOC) in fresh leaves of Moso bamboo plants as well as the interrelations between silicon and phytolith contents,the fresh leaf samples of Moso bamboo plants with different ages (1-and 3-year old) and different parent rocks (grantie,sandshale and tuff) were collected from the main production area in Zhejiang Province.The results showed that parent rock and bamboo age had a significant impact on the contents of Si and phytolith in fresh leaves of Moso bamboo plants.The contents of Si and phytolith in fresh leaves of Moso bamboo plants on the soils derived from the three parent rocks were in the order of grantie (33.19 g · kg-1) ＞ sandshale (32.64 g· kg-1) ＞ tuff (24.51 g · kg-1),and grantie (105.81 g · kg-1) ＞ sandshale (93.50 g · kg-1) ＞ tuff (59.40 g · kg-1).The contents of Si and phytolith in fresh leaves of 3-year old Moso bamboo plants were significantly higher than those of 1-year old plants.The parent rock and bamboo age did not affect the contents of organic carbon in the phytolith,but affected the PhytOC content in the dry matter.There was significant positive correlation between the Si and phytolith in the leaves from 3-year old Moso bamboo plants on the soils derived from the different parent rocks,but not for the leaves from 1-year old bamboo plants.Both parent rock and bamboo age were important factors affecting the contents of Si and phytolith in the Moso bamboo leaves.Therefore,the accurate estimation of the contents of phytolith in the plants distributed in different regions and different soil types in China should consider the influence of parent rock and plant age.关键词
