Controlling Factors of Soil CO2 Efflux in Pinus yunnanensis across Different Stand Ages
The characteristics of soil respiration (Rs) across different stand ages have not been well investigated. In this study, we identified temporal variation of Rs and its driving factors under three nature forest stands (e.g. 15-yr-old, 30-yr-old, and 45-yr-old) of Pinus yunnanensis in the Plateau of Mid-Yunnan, China. No consistent tendency was found on the change of Rs with the stand ages. Rs wa...
متن کاملStand After Clearcutting
A mixed hardulood stand composed of 33% oak (Quercus “pp.), 33% yellow-poplar (Liriodendron tulipifera L.), and 14% other spec ies, was clearcut in 1963. Twenty years lo ter a deueloping, even-aged stand of pedominantly sprout origin is domi?gated by yellow-poplar, black locust (Robinia pseudoacacia L.), red maple (Acer rubrum L.), and sweet birch (Betula lenta L.). The 0ak.s are a minor and de...
متن کاملInduced resistance and associated defence gene responses in Pinus patula
Background Plants are able to incite a type of broad spectrum resistance against pathogens upon pre-treatment with biological or chemical inducers. Systemic Acquired Resistance (SAR) and Induced Systemic Resistance (ISR) are two types of induced resistance which lead to the accumulation of specific pathogenesis-related (PR) proteins. Non-pathogenic rhizobacteria are inducing agents for ISR and ...
متن کاملSoil Microbial Community Structure and Metabolic Activity of Pinus elliottii Plantations across Different Stand Ages in a Subtropical Area
Soil microbes play an essential role in the forest ecosystem as an active component. This study examined the hypothesis that soil microbial community structure and metabolic activity would vary with the increasing stand ages in long-term pure plantations of Pinus elliottii. The phospholipid fatty acids (PLFA) combined with community level physiological profiles (CLPP) method was used to assess ...
متن کاملAnaerobic Xylanolytic Bacterium from Decayed Pinus patula Wood Chips
An anaerobic, mesophilic, sporeforming, xylanolytic bacterium was isolated from decayed Pinus patula wood chips. The cells of this organism were gram-negative rods, had peritrichous flagella, and formed terminal round endospores which distended the cell wall. Xylan, cellobiose, fructose, glucose, maltose, mannose, melezitose, raffinose, rhamnose, salicin, sucrose, and xylose were utilized. The ...
