Modeling Variation in Crown Profile with Tree Status and Cardinal Directions for Planted Larix olgensis Henry Trees in Northeast China
Crown profile models were developed for north, east, south, and west crown directions of dominant trees, intermediate trees, and suppressed trees in planted stands of Larix olgensis Henry in Northeast China. A total of 139 sample trees were randomly selected, and all branches of each tree were measured. A segmented power equation, segmented polynomial equation, modified Weibull equation, and Ko...
متن کاملLeaf conductance and CO2 assimilation of Larix gmelinii growin
carbon dioxide (CO2) assimilation, and transpiration in a Larix gmelinii (Rupr.) Rupr. ex Kuzen forest in eastern Siberia. At the CO2 concentration of ambient air, maximum values (mean of 10 highest measured values) for CO2 assimilation, transpiration and leaf conductance for water vapor were 10.1 μmol m s, 3.9 mmol m s and 365 mmol m s, respectively. The corresponding mean values, which were m...
متن کاملTranscriptomic Response to Nitric Oxide Treatment in Larix olgensis Henry
Larix olgensis Henry is an important coniferous species found in plantation forests in northeastern China, but it is vulnerable to pathogens. Nitric oxide (NO) is an important molecule involved in plant resistance to pathogens. To study the regulatory role of NO at the transcriptional level, we characterized the transcriptomic response of L. olgensis seedlings to sodium nitroprusside (SNP, NO d...
متن کاملCO2 in Planted Aquaria
CO2 is beyond comparison the most important of all plant nutrients. Without sufficient CO2, plants cannot photosynthesize and convert into energy-rich sugars, starch and all the other carbon-containing molecules that constitute a plant. It may seem odd to look at CO2 as a plant nutrient. When growing terrestrial plants, we are used to providing light, water and nutrients, but never CO2. is art...
متن کاملPhysiological evaluation of the responses of Larix olgensis families to drought stress and proteomic analysis of the superior family.
The conifer Larix olgensis has been analyzed to delineate physiological and proteomic changes that occur under drought stress. Studies of the deleterious effects of drought in the larch families have mainly focused on photosynthesis. In the present study, when the intensity of drought was increased, plant height was inhibited as both POD and MDA levels increased, which indicates oxidative stres...
