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...

growth in plants is defined as irreversible increase in volume and size. these changes are varied depending on stage of growth and physiological activity of the fruit tree. this research was conducted to determine the duration period of fruit growth and development and to come up with a mathematical model representing the relationship between fruit diameter, volume, and fruit fresh and dry weig...

to investigate effect of calcium and growth medium on lilium (asiatic hybrid lilium bulbs “tresor” cultivar) and nutrients uptake, a factorial experiment based on completely randomized design was conducted by three levels of calcium in nutrient solution (2, 4 and 6 mm*) and five growth media (100% perlite, 70% perlite + 30% cocopeat, 50% perlite + 50% cocopeat, 30% perlite + 70% cocopeat, 100% ...

iran is the center of origin as well as variation for pomegranate (punica granatum l.). also, iran is one of the most important countries in the world in terms of pomegranate culture and production. monitoring morphological and physiological changes which occur during fruit growth and development is an important determining in orchard management decisions. the aim of the present research was to...

This paper describes the use of atomic force microscopy to directly image surface-attached 3-5 nm diameter gold nanoparticle seeds before and after seed-mediated growth into gold nanorods (Au NRs) and other shapes (spheres, triangles, and hexagons). Results show that Au NRs form from seeds growing in either one or two directions. A direct correlation exists between seed diameter and NR diameter...

OBJECTIVE Epidemiologic studies have shown associations between impaired fetal growth and risk for coronary heart disease in adults. The underlying mechanisms are unknown. We investigated whether restricted intrauterine growth affects cardiac structure. METHODS We performed echocardiography on 216 9-year-old children who were measured previously at birth. The diameter of the coronary left and...

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...

study of soil and plant relationships is nessesery for ecological- based and appropriate management. the objective of this study is to determine the influence of edaphic properties on haloxylon persicum growth and also, indentifing growth limiting soil properties for saxaul. the study was performed through the stratified random sampling and 3 sites were selected as follow: planted strong saxaul...

BACKGROUND If undetected, infrarenal Abdominal Aortic Aneurysm (AAA) growth can lead to rupture, a high-mortality complication. Some AAA patients exhibit inhomogeneous luminal contrast attenuation at first-pass CT angiography (CTA). This study assesses the association between this observation and aneurysm growth. METHODS Sixty-seven consecutive pre-repair AAA CTAs were included in this retros...
