pistacia atlantica is the most important tree species for the economy of many rural areas in west of iran, but no effort has been made for the genetic improvement of this species. the aim of this investigation was to study the genetic variation and inheritance of early growth traits in p. atlantica. for this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...

Grape is important crop with high nutritional value, however there is a great need for improving the quality of the crop. Cultures were maintained in vitro on MS medium supplemented with 2.5 mg/L BAP+ TDZ 3.0 mg/ L. The effect of different doses of gamma irradiation as well as chemical mutagenesis by Sodium azide was studied. It was noted that doses up to 5 Gy helped to increase plant height fr...

In a large number of plant species, including maize, different phenotypic traits have undergone major changes through the breeding process, resulting in creation varieties and hybrids good agronomic performance. This study aimed to examine variability height (PH) uppermost ear (EH) maize top cross obtained from crossing 31 local landraces with three genetically divergent testers (L217, L73B013 ...

Many vigorous herbaceous perennials need early growth regulation. Treatment at the plug stage could improve early growth control or maintain product size in the plug tray. Concise (uniconazole, Fine Americas, Inc.), is a growth regulator labeled for use on ornamental greenhouse crops in the US. We treated plugs of five herbaceous perennials with a 2-minute dip into 0, 1, 2, 3, 4 or 5 mg/L Conci...

The geometric features of agricultural trees such as canopy area, tree height and crown volume provide useful information about plantation status and crop production. However, these variables are mostly estimated after a time-consuming and hard field work and applying equations that treat the trees as geometric solids, which produce inconsistent results. As an alternative, this work presents an...

in order to investigate effects of plant density and fertilizer rates on agronomic characteristic and yield tobacco (nicotiana tabacum) (cv k326) an experiment was conducted in the experimental field of tirtash research and education center. design of experiment was randomized complete block with factorial arrangement with three replications and 36 treatments conducted in 2007 year. treatments ...

in order to study the morphological characteristics affecting yield of echium amoenum under different nutritional treatments and different plant densities, a factorial experiment based on rcbd design with three replications was conducted at agricultural research station, ferdowsi university of mashhad, iran in 2011-2013 growing seasons. the experimental treatments were all combination of three ...

The measurement of a plant growth without interrupting its natural growth is essential since its diameter and height are related to the development of a tree as well as the water contents. Therefore main objective of this project is to find the diameter and height of a plant. Hence in this proposed work, an interface between a C3008 smart camera and a computer has been developed. Main advantage...
