Studies on the biology of flowering, nectar production and pollination of apple trees. Part I. Flowering and pollination



Studies on the biology of flowering, nectar production and pollination of apple trees. Part I. Flowering and pollination



Pszczel, Zesz Nauk Odd Pszczel Inst Sad w Pulawach (22): 129-145



Flowering, pollination, insect visitation and cropping were studied in 15 apple cvs in relation to weather. In cool weather the difference in the start of flowering in the earliest (Stark Earliest) and the latest to flower (Golden Delicious) was 6 days; in warm, sunny weather the difference was 4 days. The effects of weather on insect activity and pollination are discussed.
