RESPONSE OF CONTAINER-GROWN ACER SACCHARUM TO DROUGHT STRESS

Transcriptomic Analysis of Soil-Grown Arabidopsis thaliana Roots and Shoots in Response to a Drought Stress

Drought stress has a negative impact on crop yield. Thus, understanding the molecular mechanisms responsible for plant drought stress tolerance is essential for improving this beneficial trait in crops. In the current study, a transcriptional analysis was conducted of gene regulatory networks in roots of soil-grown Arabidopsis plants in response to a drought stress treatment. A microarray analy...

Seasonal Occurrence of Xylem Embolism in Sugar Maple (Acer saccharum)

Xylem embolism, the reduction of water flow by air-filled vessels, was measured in a stand of 5to 8-year-old sugar maple (Acer saccharum Marsh.) saplings growing in a nursery bed in northwestern Vermont. Embolism was quantified as percentage loss in hydraulic conductivity of trunk and branch segments relative to maximum values obtained by removing air from vessels by repeated high pressure (173...

DEVELOPMENT OF GENE-BASED MICROSATELLITE MARKERS IN Acer saccharum MARSH

Morpho-physiological responses in Alnus subcordata and Acer velutinum seedlings to drought stress

In this study, the effect of drought stress on morphological and physiological characteristics of two forest species: Alnus subcordata and Acer velutinum, which are used in natural forest restoration and afforestation, was evaluated. A factorial experiment was conducted based on a completely randomized design with two factors (two species and four levels of drought stress: (25% (severe stress),...

Chlorophyll content monitoring in sugar maple (Acer saccharum).

We conducted two experiments to determine the usefulness of a chlorophyll content meter (CCM) for the measurement of foliar chlorophyll concentration in sugar maple (Acer saccharum Marsh.) in the fall color period. In Experiment 1, four sugar maple trees were visually assigned to each of four fall foliage color categories in October 1998. On four dates in the fall of 1999, leaves were taken fro...
