Online published on 2 January, 2017. Abstract The present investigation entitled, “Effect of different chemicals on vegetative growth, flowering and corm production in gladiolus cv. Phule Neelrekha was carried out at NARP Ganeshkhind Pune, during 2012–13. The experiment was laid out in randomized block design with three replication and seven treatments, viz., Thiourea 2%, Hydrogen cyanamide 1%, Potassium nitrate 1%, NAA 500 ppm, GA3 200 ppm, Water soaking and control. Uniform sized gladiolus corms were soaked in solutions ofdifferent concentrationfor 24 h before planting. Results revealed that the vegetative and floral characters were significant in the plants grown from the corms treated with hydrogen cyanamide 1% followed by potassium nitrate and GA3. The corms treated with hydrogen cyanamide 1% produced the plants with most superior characters in respect of plant height (142.47 cm), number of leaves per plant (11.10), spike length (114.54 cm), rachis length (55.96 cm), diameter of flower (9.99 cm), number of florets per spike (20.04), corm size (8.63 cm), corm weight (111.81 cm), number of cormels per plant (25.74) and weight of cormels per plant (23.30 g) than all other treatments. All the chemical treatments along with water soaking were superior to control. To effect of different chemicals hydrogen cyanamide 1% was most promising in all vegetative and floral character in cv. Phule Neelrekha. Top Keywords Gladiolus, Corm, Thiourea, Hydrogen Cyanamide, Potassium Nitrate, Naphthalene Acetic Acid, Gibberellic Acid, Water soaking. Top |
