Due to small cormel sizes, a higher proportion (about 92%) of the cormel yield could be classified as unmarketable.
Fresh corm weight, number of cormels, fresh cormel weight and total yield of corm and cormel (tuber) were significantly higher (P[?
The results are in agreement Baldotto and Baldotto (2013) who observed an increased number of cormels per plant, cormel diameter and cormel weight per plant might be due the effects of humic acid to make more mineral nutrients available to plants Table-3.
Cultivar Effects on Growth, Yield and Cormel Production of Gladiolus (Gladiolus grandiflorus L.
Effect of corm size and fifferent doses of phosphorus on the growth, corm and cormel
development of gladiolus.
Plant regeneration through in vitro cormel
formation from callus culture of Gladious primulinus Baker.
The increase of the total costs of production in response to the increase of the weight of the seedling type used in the tannia propagation cultivated with and without hilling confirms that as the average weight of the cormel
used as the seedling increases, then the participation of this component in the production cost will be higher (PUIATTI et al.
Majority (92%) of the farmers interviewed cultivate cocoyam for both the cormel
tips (Simonsen and Hildebrandt 1971) or cormel
slices and basal leaf region (Kamo 1994) but in our results we observed shoot from callus initiated from slices of cormel
In general, shape, size and weight of the cormels
seems to represent no obstacle for costarican exporters, but surface damages to the cormel
and the presence of severe damage were beyond the tolerance limits established by the proposed standard of grade and quality.
A large corm may be produced from a cormel
in two or three years.
In vitro cormel
production from nodal buds and cormel
tip has been achieved successfully .
