We examined the effect of competition on stem growth of Picea glauca and Populus tremuloides in boreal mixedwood stands during the stem exclusion stage. We combined traditional approaches of collecting competition data with dendrochronology to provide retrospective measurements of stem diameter growth. Several competition indices including stand basal area (BA), the sum of stem diameter at brea...
Aquilegia `Rose-White' flowered from seed in about five months without vernalization. GA4/7 treatment increased stem height, induced earlier flowering, and increased the number of flowers/ plant. Each of these responses, however, was dependent upon both rate (10, 25, or 50 ppm) and timing of application (4-, 8-, or 12-leaf stage). Treatment at the 4-leaf stage resulted in earlier flowering at a...

The objective of this research was to develop a stem height measurement system forMiscanthus giganteus (MxG), to be used as a component in a future Look Ahead Yield Monitor (LAYM). For this purpose, a SICK LMS 291 LIght Detecti...
The number of long-term surviving stem cell transplant (SCT) recipients has increased steadily, and attention has now extended to the late complications of this procedure. The objective of this study was to investigate relationship among growth and endocrine functions in long-term adult survivors of childhood SCT. The inclusion criteria of this study were survival at least 5 yr after SCT and ac...
To evaluate the effect of dipping time of bulb in complete NPK fertilizer on quantitative and qualitative traits of tuberose (Polianthes tuberosa L. cv. Double), a factorial experiment based on completely randomized design with four replications was conducted under the greenhouse conditions. The first factor was three bulb-dipping times (20, 40 and 60 min) and the second factor was four concent...
تأثیر پلیمرهای سوپرجاذب بر خصوصیات مورفولوژیک گیاه رزماری (Rosmarinus officinalis) در شرایط تنش خشکی
In order to study the effects of superabsorbent polymers and drought stress on some morphological characteristics of Rosmarinus officinalis, a pot experiment was conducted as factorial, based on completely randomized design with four replications, in which factors included four levels of drought stress (irrigation up to 100, 75, 50 and 25 percent of field capacity (FC) level, respectively) and ...
In order to investigate the effect of integrated management of phosphorus (P) fertilizer and phosphate solubilizing microorganisms on nutrients concentration and yield of two barley cultivars, a factorial greenhouse experiment was carried out based on randomized complete blocks design with three replications in 2011. Treatments consisted of two barley cultivars (Bahman and Fasih) and five types...
In order to improve the quantitative and qualitative traits of lisianthus (Eustoma grandiflorum “Mariachi Blue”) a factorial experiment ws performed as completely randomized design at three levels of vermicompost (0, 5 and 10% v/v) and humic acid (0, 2 and 4 kg/m3) with three replications, under the greenhouse conditions. Evaluated traits were number of Leaves, buds and branches, pe...
introduction: the most abundant of agricultural soils in iran, are calcareous. in calcareous soils, phosphorus fertilizers use efficiency is low. the usage of soil microorganisms is one of the effective ways to increment the uptake of phosphorus in calcareous soils. this microorganisms using various mechanisms, including the production of plant hormones or the production of organic and inorgani...
The timing of periodic life cycle events in plants (phenology) is an important factor determining how species and populations will react to climate change. We evaluated annual patterns of basal-area and height growth of coast Douglas-fir (Pseudotusga menziesii var. menziesii (Mirb.) Franco) seedlings from four seed sources that were planted in four diverse environments as part of the Douglas-fi...
