The prevention of flower bud and leaf abscission in pot roses during stimulated transport


Journal of the American Society for Horticultural Science 101(6): 658-660
The prevention of flower bud and leaf abscission in pot roses during stimulated transport
Pot roses (Rosa hybrid cv. 'Pink Margo Koster', 'Orange Margo Koster' and 'Red Garnette') were sprayed with naphthaleneacetic acid (NAA) or 60(benzylamino)-9-(2-tetrahydropyranyl)-9H-purine (PBA) prior to simulated truck shipment which lasted 5 or 6 days to study the effect on flower bud and leaf abscision and on leaf senescence. Simulated shipment under refrigerated conditions (1-3.degree. C) prevented bud and leaf abscission. 'Red Garnette' and 'Orange Margo Koster' were severely affected. Observations under home conditions for 10 days after this warm shipping temperature revealed that all 3 cultivars had severe leaf senescence. NAA spray (15 and 30 ppm) severely accelerated leaf abscission and senescence. NAA prevented bud drop, but the buds did not open. PBA (50 ppm) greatly reduced leaf abscission both during shipment and in home conditions. PBA also prevented bud drop and flowers subsequently opened normally.
