Abstract:
|
The study based on variation pattern and ecology of Lanceolata linn supported with transplant experiment reveales that the erect or prostate habit and the pubesence of the leaves are the only two variable characters that are retained if such plants are grown side by side under the uniform conditions of growth. The study recognized four eco types:
1. Plants with erect and smooth and erect scapes (`Es'type);
2. Plants with hairy and erect leaves (`Eh'type);
3. Plants with prostate and smooth leaves and decumbent shape (`ps type)
4. Plants with prostate and smooth leaves and document scape (`ph type).
A Comparative ecological study of these four types reveals that these differ from one another in number of fruit/spike, fruit output/plant, fruit dimension, length of the spike, seeds etc. Besides,comparative account of the germination behavior of both fresh and harvested seeds as well as pre-stored seeds collected from four types of species are given in the study. |
