Trying to use tip leaflet of rose plants as a
sample to estimate leaf area and to separate rose cultivars, in an experiment
we took leaf images from three different stem layers of four garden roses.
After preliminary image pre-processing measures, some important leaf geometric
features such as leaf and leaflet area, perimeter, circularity and leaflet
length and width were measured or calculated. Analysis of variance showed that
it would be possible to separate rose cultivars by including only two leaf
properties, i.e., tip leaflet angle and leaflet area to leaf area ratio. It was
also determined that three leaf layers along the rose stem can be recognized
and categorized by implementing just angle of tip leaflet. Leaflet area was
agreeably approximated by fitting a simple linear model to the product of
leaflet minor and major axes. Further analyses indicated that some leaflet
properties such as solidity, perimeter and circularity can be used as
significant criteria to distinguish rose cultivars, however other features like
leaflet elongation and rectangularity were quite poor and insignificant in this
case. In conclusion, it was determined that rose leaflet tip angle not only has
the ability of being as a good morphometric marker in separating rose stem leaf
layers but also it is capable of identifying different rose cultivars.
