High resolution measurements of stem diameter variation provide a means to study short-term dynamics of tree growth and water status. In this 14-month study, daily changes in stem radius of Eucalyptus globulus Labill. seedlings were measured with electronic point dendrometers in a plantation in southern Tasmania, Australia. The daily patterns of stem expansion and shrinkage were classified into...

crop production in arid and semi arid environments has been affected by drought stress. forage production have important role on animal production in this area. in order to determine the effect of irrigation intervals on the yield and morphological characteristics of forage millet, sorghum and corn, an experiment was conducted in a split plot with a randomized complete block design with four re...

Stem taper data are usually hierarchical (several measurements per tree, and several trees per plot), making application of a multilevel mixed-effects modelling approach essential. However, correlation between trees in the same plot/stand has often been ignored in previous studies. Fitting and calibration of a variable-exponent stem taper function were conducted using data from 420 trees felled...

Tomato  (L.ycopersicon esculentum  Mill.) cv. Rio Grande  seedlings were nutritionally conditioned with solutions complete fertilizer N(60% NO3+40% NH4)-P-K (20-20-20) , N(30%NO3+70% NH4)-P-K (15-5-30) , the first two week   N(60% NO3+40% NH4)-P-K (20-20-20) and later two week  N(30%NO3+70% NH4)-P-K...

zinnia elegans, an annual flowering plant of the genus zinnia, is one of the best known zinnias. present study was conducted to evaluate the effect of different growing media on the growth and flowering of zinnia elegans. seven different growth media including coconut compost, silt, soil loam, leaf manure, (leaf manure + silt; 2:1), (coconut compost + soil loam; 1:1) and (leaf manure + soil loa...

BACKGROUND AND AIMS Climate projections predict drier and warmer conditions in the Mediterranean basin in the next decades. The possibility of such climatic changes modifying the growth of two Mediterranean species, Erica multiflora and Globularia alypum, which are common components of Mediterranean shrublands, was assessed. METHODS A field experiment was performed from March 1999 to March 20...
