Effects of elevated carbon dioxide concentration and temperature on needle morphology and shoot growth in Norway spruce
… of [CO2] and T on needle morphology and shoot growth. It was made by using whole-tree chambers around mature trees. In this research the main goal was to find out what effects elevated [CO2] and T had on specific needle area (SNA), needle density, needle length and width, annual shoot …

Foliar damage and shoot growth changes resulting from exposure of eastern white pine seedlings to nightly acidic mists
Eastern white pine is an important coniferous forest species of the northeastern United States where nightly acidic mists may be a factor in the decline of highland forests. During 3 studies, experimental mists were applied nightly in order to simulate nocturnal misty conditions common in the …

Variation for root and shoot growth among wheat cultivars and the effects of barley yellow dwarf virus on growth
… wheat cultivars to evaluate differences in root growth, to evaluate the effects of barley yellow dwarf virus (BYDV) on root and shoot growth, and to study the effects of a plant growth regulator on root growth of healthy and BYDV infected plants. Cultivars evaluated were Caldwell, Cardinal, …

The role of plant hormones, carbohydrates and indolebutyric acid in root and shoot development of two transplanted woody species
… plant hormones in the control of root and shoot development of woody plants. An experiment was conducted to determine the effectiveness of IBA root sprays applied to seedling red oaks up to two weeks prior to planting. Bare root Quercus rubra seedlings were sprayed with 0, 3000, 6000 and …

ESTABLISHMENT OF TURFGRASS FROM SEED AND SOD IN SAND BASED SYSTEMS COMBINING SPRINKLER AND SUBSURFACE DRIP IRRIGATION SYSTEMS
… when planted in the spring. Creeping bentgrass shoot growth in the summer was similar for all the SDI and overhead treatments. However, in the spring, the creeping bentgrass shoot growth was significantly better for the SDI treatments compared to the overhead treatment.</p> <p>The ultra dwarf …

Scope, Selectivity, and Mechanism of the Prins Cyclization of Delta,&egr;- and &egr;,zeta-Unsaturated Ketones With Lewis Acids to 1,3-Halohydrins
Finally, reduction in R:FR increased vertical growth and erectness of both BAS1 gene transformants and control plants, however, overexpression of BAS1 gene induced dwarfism in transgenic creeping bentgrass by delaying vertical shoot growth and altering shoot architecture. True BAS1 transformants …

The Control of the Root to Shoot Ratio of Radish (Raphanus sativus L.)
The regulation of the root to shoot ratio of radish was studied with emphasis on the factors controlling assimilate distribution. Analysis of indol-3yl-acetic acid (lAA) and gibberellin levels in radish through its vegetative cycle revealed that shoot hormone levels, initially high, declined with …

Some aspects of nitrogen nutrition on selected Ilex
… coefficients were found between plant growth (dry wt accumulation) and both leaf N content and soil solution nitrates, while low correlation coefficients were found between soil nitrates and plant growth. Shoot growth of 'Helleri' and 'Burfordi' was not increased by N levels higher than …

An in vitro system for selection and characterization of acifluorfen-tolerant Solanaceous plants
Callus growth and shoot regeneration from long-term cultured Solanaceous genotypes depended on the genotype, growth regulators, and thiamine concentrations. Most Solanaceous genotypes produced more shoots and better shoot growth on high than low levels of thiamine. The effect of thidiazuron on …

Impact of predation by Laricobius nigrinus (Coleoptera: Derodontidae) and Leucotaraxis spp. (Diptera: Chamaemyiidae) on Adelges tsugae (Hemiptera: Adelgidae) and Tsuga canadensis (Pinales: Pinaceae) tree health
… rate to the negative control on 1-2 year old shoot growth. In addition, significantly more shoots were produced for treatment branches with the highest La. nigrinus density. This also led to a significantly reduced aestivating sistens density compared to the no predator treatment. However, …
