| 1 | Allometric models for aboveground biomass of six common subtropical shrubs and small trees显示文摘The aboveground biomass(AGB)of shrubs and small trees is the main component for the productivity and carbon storage of understory vegetation in subtropical secondary forests.However,few allometric models exist to accurately evaluate understory biomass.To estimate the AGB of five common shrub(diameter at base<5 cm,<5 m high)and one small tree species(<8 m high,trees’s seedling),206 individuals were harvested and species-specific and multi-species allometric models developed based on four predictors,height(H),stem diameter(D),crown area(Ca),and wood density(ρ).As expected,the six species possessed greater biomass in their stems compared with branches,with the lowest biomass in the leaves.Species-specific allometric models that employed stem diameter and the combined variables of D~2H andρDH as predictors accurately estimated the components and total AGB,with R^(2) values from 0.602 and 0.971.A multi-species shrub allometric model revealed that wood density×diameter×height(ρDH)was the best predictor,with R^(2) values ranging from between 0.81 and 0.89 for the components and total AGB,respectively.These results indicated that height(H)and diameter(D)were effective predictors for the models to estimate the AGB of the six species,and the introduction of wood density(ρ)improved their accuracy.The optimal models selected in this study could be applied to estimate the biomass of shrubs and small trees in subtropical regions. | Cheng Huang Chun Feng Yuhua Ma Hua Liu Zhaocheng Wang Shaobo Yang Wenjing Wang Songling Fu Han Y.H.Chen | 2022 | Journal of Forestry Research2022，33，4： | 1 |
| 2 | Study on the Phenotypic Mutation Generated from ^(60)Coγ-ray Irradiated Oxlias triangularis Purpurea Regeneration System显示文摘Mutations induced from tissue culture are easily to be separated,which might be propagated in the same medium,especially for the color-leaf ornamental grass,Oxalis triaggularis purpurea.Mutations of the ornamental traits in the tissue culture bottle could be investigated easily.The 35 d regeneration system group showed the lowest adventitious bud number and adventitious root number among 4 inoculation dates by 50 Gy dose of ^(60)Coγ radiation.More studies were carried out based on the 35d differentiation state of O.triangularis purpurea regeneration system.The 35 d regeneration system was then irradiated by 10,25 and 50 Gy doses of ^(60)Coγ rays.Numbers of adventitious buds and roots induced from the regeneration system were cut down with the increment of radiation doses.Seedling length was not distinctly reduced at the absorbed doses of 10 and 25 Gy,but reduced distinctly under 50 Gy of ^(60)Coγ irradiation.The optimal irradiation dose for 35 d O.triangularis regeneration system survival and mutation induction was approximately 25 Gy.The M_2 phenotypic mutation rate was 2.9%,especially,and the leaf number mutation accounted for 76%of the total mutation.The phenotypic mutations,especially in the 10 Gy group,on 0.1 m M Vc containing MS medium were recovered,which indicated that ROS plays a key role in the phenotypic mutation induced by ^(60)Coγ -rays. | Jie REN Qi ZHU Yanqiong MENG Fei TANG Yun XUAN Dan SHI Jingjing WANG Yongjin DENG Songling FU | 2017 | Agricultural Science & Technology2017，18，5： | 0 |
