The role of many insect species in crop pollination has been widely studied. The use of entomophilous pollination, commonly adopted for other crops, may be of key importance in order to improve seed yields in seed‐propagated globe artichoke (Cynara cardunculus var. scolymus) cultivars. In this regard, in a 2‐year field experiment, the role of two honeybees (Apis mellifera ligustica and A. mellifera siciliana) and one bumblebee (Bombus terrestris) was evaluated on the seed production of two globe artichoke cultivars in caged‐protected environments. Overall, the number and weight of seeds plant−1 and head−1, 1,000 seed weight and fruit setting were higher in caged plants with imposed pollination than open field plants. The pollination efficiency was both insect and cultivar dependent. Both honeybee species performed better on the Mediterranean cultivar ‘Violetto di Sicilia’, while the bumblebee performed better on the Brazilian cultivar ‘NP4’. These results could be very useful to modernise the agronomic management of globe artichoke and reduce the costs of cultivation. In addition, such knowledge can be used to improve the seed production in globe artichoke seed‐propagated cultivars and cardoon. This will benefit the bioenergy, nutraceutical, cosmetic and ornamental applications.

昆虫授粉媒介提高朝鲜蓟(Cynara cardunculus var。scolymus)的种子产量

许多昆虫物种在农作物授粉中的作用已得到广泛研究。利用虫媒授粉,其他作物普遍采用的,可能是关键的重要性,以提高种子繁殖朝鲜蓟种子产量(辛娜拉cardunculus变种洋蓟)品种。因此,在为期2年的田间试验中,在笼养保护环境中,评估了两种蜜蜂(蜜蜂Apis mellifera ligustica和蜜蜂A. mellifera siciliana)和一只大黄蜂(Bombus terrestris)的作用对两种朝鲜蓟品种的种子产量的影响。 。总体而言,种子植物-1和头-1的数量和重量强制授粉的笼养植物的种子重量和坐果率要比裸地植物高1,000。授粉效率既取决于昆虫,也取决于品种。两种蜜蜂在地中海品种“ Violetto di Sicilia”上的表现都更好,而大黄蜂在巴西品种“ NP4”上的表现更好。这些结果对于现代化朝鲜蓟的农艺管理和降低种植成本可能非常有用。此外,这些知识可用于改善朝鲜蓟播种的栽培品种和菜豆的种子产量。这将有利于生物能源,营养保健品,化妆品和装饰性应用。
