Functional and Structural Changes in Senescing Populus deltoides (Bartr.) Chloroplasts.
Chloroplasts isolated from Populus deltoides leaves were used to study age-dependent changes in the rate of cyclic photophosphorylation. Single leaves were used to measure CO(2) fixation by leaf discs, chlorophyll concentration, and ATP synthesis. The ability of chloroplasts to synthesize ATP diminished steadily from the time of full leaf expansion, regardless whether the results are expressed ...
متن کاملVariation in Wood Properties and Growth in Some Clones of Populus deltoides Bartr. ex Marsh
The present paper deals with within ramet radial, intraand inter-clonal variations in the wood element’s dimensions and specific gravity of 10 clones of Populus deltoides Bartr. ex Marsh. The growth parameters namely ramet height and DBH were also considered for the study. Study material was collected from the 10 clones of Populus deltoids raised by WIMCO Plantations Ltd. at Rudrapur (Udhamsing...
متن کاملIncreased leaf area dominates carbon flux response to elevated CO2 in stands of Populus deltoides (Bartr.)
We examined the effects of atmospheric vapor pressure deficit (VPD) and soil moisture stress (SMS) on leafand stand-level CO2 exchange in model 3-year-old coppiced cottonwood (Populus deltoides Bartr.) plantations using the large-scale, controlled environments of the Biosphere 2 Laboratory. A short-term experiment was imposed on top of continuing, long-term CO2 treatments (43 and 120 Pa), at th...
متن کاملSomatic Embryogenesis of Populus deltoides
Node, internode, and leaf explants of Populus deltoides Bartr. ex Marsh. × Populus deltoides Bartr. ex Marsh. hybrid poplar clone (89 M 066) tissue culture regenerated plantlets were used for direct and indirect somatic embryogenesis. Direct somatic embryos were differentiated on node, internode and leaf explants on Murashige and Skoog basal medium (MS) supplemented with N 6 -Benzyladenine (BA)...
متن کاملRelationships between growth stress and wood properties in Poplar 1 I - 69 ( Populus deltoides Bartr . cv . ” Lux ” ex I - 69

I-69/55) trees were collected for studying the influence 14 of growth stress level on wood properties. Growth stress indicator (GSI) was measured at 8 positions around the 15 periphery of each trunk at...
