Temporal dynamics of stomatal regulation and carbon- and water-related traits for a native tree species in low subtropical China.

Stomata are pivotal in modulating water and carbon processes within plants. However, our understanding of the temporal dynamics of water- and carbon-related traits, as influenced by stomatal behavior, remains limited. Here, we explore how stomatal regulation behavior and water- and carbon-related traits vary with changing environments by examining the seasonal variations in these traits of the native tree species Schima superba in low subtropical China.

Transcriptome analyses and weighted gene coexpression network analysis reveal key pathways and genes involved in the rapid cold resistance of the Chinese white wax scale insect.

Mechanistic Study of 1,4-Benzodiazepine-2,5-diones from Diphenylamine and Diethyl 2-Phenylmalonate by Density Functional Theory.

The mechanisms for the reaction between diphenylamine and diethyl 2-phenylmalonate were investigated using M06-2X-D3/6-31+G(d,p) method and level, and the SMD model was applied to simulate the solvent effect. The computational results suggested that diphenylamine and diethyl 2-phenylmalonate can convert into 4-hydroxy-1,3-diphenylquinolin-2(1)-one via a series of reactions (addition reaction, dealcoholization reaction, enolization reaction, dealcoholization reaction, ring-closure reaction, and H-shift reaction). And HO, as the catalyst, can play an important role to promote these reactions.

Development and Evaluation of Models for the Relationship between Tree Height and Diameter at Breast Height for Chinese-Fir Plantations in Subtropical China.

Tree diameter at breast height (dbh) and height are the most important variables used in forest inventory and management as well as forest carbon-stock estimation. In order to identify the key stand variables that influence the tree height-dbh relationship and to develop and validate a suit of models for predicting tree height, data from 5961 tree samples aged from 6 years to 53 years and collected from 80 Chinese-fir plantation plots were used to fit 39 models, including 33 nonlinear models and 6 linear models, were developed and evaluated into two groups. The results showed that composite models performed better in height estimate than one-independent-variable models.
