Abstract/ Executive Summary:

The experiment was carried out during the period from November’2008 to October, 2009 to compare the morphology of five gladiolus flowers genotypes with respect to plant height, length and breadth of leaf, number of leaves per plant, length of flowers, breadth of flower, weight of flower, weight of single stick, length of spike, length of rachis, flowers per plant, days to reach 50% spike initiation, number of corm and cormel per plant, breadth of corm and weight of cormel per plant. The results indicated the significant variation amongst the gladiolus genotypes with respect to studied morphological characteristics as well as with yield, yield attributes and plant height. The plant height was higher (58.6cm) and lower (46.52cm) in yellow and orange /red respectively due to genotype. The lengths of leaves were almost same but higher with yellow and violet (42.25/42.05 cm) than the white and orange ones where the smallest length was recorded for red (33.36cm) one. Almost same trends were recorded for breadth of leaves with the exception of few. The average number of leaves was highest for white (12.25) followed by red, violet, orange and yellow respectively. Most of the parameters of flower characteristics did not maintain regular trend and correlation when considered in terms of sequences starting from white to red as shown in the table 1, 2 and 3. The recorded results clearly indicate that the white genotype has the best planting materials which may be planted for luxuriant growth of plants and production of excellent flowers.

Keywords: Gladiolus, Genotype, Morphology, Corm & Cormel.

Location: Commercial Flower Garden of Society and Human Development Organization, Tangail (SAHDOT)

Start Date: 00-11-2008

End Date: 00-10-2009

Program Area: Variety and Species

Commodity: Gladiolus

Objectives:

To find out the variability among the genotypes and to ascertain suitable genotypes of gladiolus flower
To prescribe measure for increasing production of flower, corm and cornel of gladiolus

Methodology:

The present experiment was carried out at the Commercial Flower Garden of Society and Human Development Organization, Tangail (SAHDOT) during the period from November’2008 to October’2009 to investigate the morphology of different gladiolus genotypes. The experiment examined five gladiolus genotypes. The studied characteristics were plants height, leaves, flowers, corm and cormels. The experiment was laid out in a randomized Complete Block Design each having 5 replications. The unit plot size was 2m×1m. The experimental plot was opened in the first week of November 2008, and was exposed to the sun for a weak. After a week manures (cow dung) along with all other fertilizers were applied accordingly. The entire amount of cow dung and Triple Super Phosphate was applied during final land preparation. Muriate of Potash was applied in two installments at 25 and 50 days after planting of corms. Nitrogen was applied as per treatment at 15, 30 and 45 days after germination. Medium sized(two years aged) corms were planted at 6 cm depth in furrows on 5th November 2008 following the row to row spacing of 25cm and plant to plant spacing of 15cm. Different Intercultural operations like weeding, irrigation, earthing up, stacking, pesticide and fungicide application were performed as and when necessary. The spikes were cut when one or two lower most florets showed color but still in tight bud stage ). Harvesting of corms and cormels were performed only when leaves turned into brown (Mukhopadhyay, 1995). Data were collected and recorded from the selected genotypes in accordance with different parameters. The recorded data on the selected parameters were set for statistical analysis. The mean for collected data for each treatment was calculated.

Achievement/Findings:

Results indicated significant variation amongst the gladiolus genotypes with respect to studied morphological characteristics as well as with yield, yield attributes and plant height. The plant height was higher in yellow (58.6cm) and lower (46.52cm) in case of orange /red due to genotype.
