Trophic versus environmental factors controlling in vitro bulb formation in onion and garlic micropropagated plants


Acta Horticulturae ( 433): 435-443
Trophic versus environmental factors controlling in vitro bulb formation in onion and garlic micropropagated plants
In vitro experiments were carried out on clonal lines of onion from the De Mulhouse population, onion Radar and garlic cultivars Rose du Var, Moulinor, Messidrome and Rose de Lautrec. Testing daylength influence on bulbing allowed spring and autumn garlic cultivars to be distinguished. The addition of incandescent lamps to fluorescent light reduced the daylength requirements in garlic and induced bulbing in onion, provided they had at least 16 h daylength.
