EFFECT OF GROWTH REGULANTS ON POT-CHRYSANTHEMUM DEVELOPMENT IN LOAM AND LOAMLESS COMPOSTS |
| Author: | J.C.R. Seager |
| Abstract:
Small and moderate reductions in height of pot-chrysanthemums were obtained following application of Cycocel (to compost) and B-Nine (to foliage) respectively. Height was further reduced when Phosfon was applied to the compost or used in solution as a cutting dip prior to planting. However, the latter method induced variable results. Plants grown in peat/sand were less responsive to Cycocel and Phosfon than when grown in JIP, suggesting greater chemical adsorption by the peat/sand medium. Cycocel and Phosfon increased foliar greenness. Cycocel and B-Nine induced a small increase in flower number, while Phosfon delayed flowering. | |
