Variation 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 کاملتحمل خشکی نهال‌های یک‌ساله پنج کلن صنوبر دلتوئیدس (Populus deltoides Bartr. ex Marsh)
در پژوهش پیش‌رو نهال‌های صنوبر دلتوئیدس (Populus deltoides Bartr. ex Marsh)در مدت چهار ماه تحت تنش خشکیقرار گرفتند. قلمه‌های پنج کلن صنوبر دلتوئیدس تهیه‌شده از خزانه تتارد ایستگاه چمستان در ایستگاه تحقیقات باغبانی قائمشهر کاشته شدند. در خردادماه وقتی نهال‌ها به قطر و ارتفاع مناسب رسیدند، نهال‌های یک‌دست انتخاب و با 20 تیمار شامل پنج سطح کلن (10/63P.d.، 51/63P.d</e...
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 کاملPhotosynthesis of Nuttall oak (Quercus nuttaZZii Palm.) seedlings interplanted beneath an eastern cottonwood (Populus deltoides Bartr. ex Marsh.) nurse crop
An afforestation system which utilizes the pioneer species eastern cottonwood (Populus deltoides Bartr. ex Marsh.) as a nurse for slower growing, disturbance-dependent species is under evaluation as a forest rehabilitation tool on former agricultural land in the Lower Mississippi River Alluvial Valley, USA. The primary objectives of this study were to quantify understory light availability in t...
متن کاملFunctional 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 ...
