Efficient monitoring of phenology in chestnuts

Chestnuts (Castanea spp.) are ecologically and economically important forest fruit trees. They cultivated for their nutritious nuts. To select varieties to be in chestnut orchards, phenology needs considered. In this work, we adapt the international BBCH system chestnuts by building on an existing phenological scale used some European countries these species. The proposed uses eight of ten principal growth stages trees secondary that specific We tested it monitoring during three growing seasons, illustrating its suitability high-throughput phenotyping studies. Overall, approach used, despite inherent limitations, is straightforward, accessible flexible, allowing particularly precise description complex flowering
