Flower-bud blasting in tulips


, : Flower-bud blasting in tulips. Acta Horticulturae (47): 149-155

The physiological disorder of blasting is promoted in susceptible tulip cvs by certain storage and greenhouse conditions. Similar effects resulted from exposure of bulbs to 1-3 p.p.m. ethylene for 6 weeks during storage, or of plants in the greenhouse to 0.5 p.p.m. for 3 days, or injection of the flower buds in the greenhouse with ABA (0.5 ml of 20 mg/l solution).

An increase in bulb N content brought about by N applications during growing made tulip bulbs which had been exposed to ethylene more susceptible to flower bud blasting. In the absence of exposure to ethylene there was no relationship between N an...

Flower size was smaller with 4 deg cooling, although the plan...
