Analysis of phenolic compounds in onion nectar by miniaturized off-line solid phase extraction-capillary zone electrophoresis
(Royal Society of Chemistry, 2014)Onion is an important vegetable crop which depends heavily on cross-pollinating insects for any significant increase in seed production. Nectar is the most important floral reward offered by plants. Minor components such ... -
Appetitive behavior of the honey bee Apis mellifera in response to phenolic compounds naturally found in nectars
(Company of Biologists, 2019)The honey bee is the most frequently used species in pollination services for diverse crops. In onion crops (Allium cepa L.), however, bees avoid visiting certain varieties, being attracted differently to male sterile (MS) ... -
Nectar and flower traits of different onion male sterile lines related to pollination efficiency and seed yield of F1 hybrids
(Entomological Society of America, 2013-06)Honey bees are the main pollinators of onion crops for seed production, but owing to low attractiveness of flowers, pollination is often inadequate. Pollination problems result in low seed yields. This problem is accentuated ... -
Onion Hybrid Seed Production: Relation with Nectar Composition and Flower Traits
(2018-05)Onion (Allium cepa L.) is one of the main vegetable crops. Pollinators are required for onion seed production, being honeybees the most used. Around the world, two types of onion varieties are grown: open pollinated (OP) ...
