Morphological variation of Plantaqo major L.
(Plantaginaceae) from different altitudes. -----------------------------------------------------------Investigation on the morphology of Plantaqo major L. from
different altitudes has been carried out. Plantaqo major has
a wide distribution and great variation in morphology. This
morphological variation tend to be influenced by the
environmental factors of the different altitudes.
Observations on Plantaqo major were conducted from several
altitudes, 700-800 m, 1300-1400 m, 1800-1900 m and 2300-2400 m
respectively. Morphological variations were studied on the
vegetative and the generative organs. Vegetative characters
were based on length, width, diameter and trichome of leaves,
while generative characters were based on the scape, spike,
bract, sepal, seed and pollen. The result showed that there
were great variations on the morpholoy of vegetative and
generative organs from the samples which were taken from
different altitudes. Statistical analysis showed that
Plantaqo major taken from 2300 - 2400 m had significant
difference with othersamples from three other altitudes,
while Plantaqo major which were collected from 1300 - 1400 m
showed great similarities with Plantaqo major from 1800 1900 m. Plantaqo major which were taken from 700-800 m had
greater individual variation " compared to Plantaqo major wich
were taken from the three other altitudes
