Nectar production of quince (Cydonia oblonga Mill.) cultivars

open access: yesInternational Journal of Horticultural Science, 2000
Nectar production of six quince cultivars were measured during three consecutive years. The nectar production of quince can be regarded to be small compared to other temperate zone fruit tree species since quince flowers contained 1.07 ± 0.06 mg of ...
