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 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...
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 کاملPerformance of poplar (populus deltoides bartr.) and its effect on wheat yield under agroforestry system in irrigated agro-ecosystem, India
The quantitative performance of wheat crop under 1-5 year old poplar plantations in irrigated agro-ecosystem was studied to ascertain the biological yield of tree and crop. Results revealed that growth and yield of wheat decreased significantly with the increase in poplar age. The per cent reduction in net grain yield was 17% under one year old poplar plantation, which increased to 52.15% under...
