Abstract

During tree dormancy phase, the appearance and internal structure of P. mume flower buds continue to develop with cultivar-dependent developmental rate.
In a previous study, we established a modified BBCH scale to define the developmental stage of dormant flower buds and found that BBCH 53 is the stage when chilling requirement is fulfilled.
Cultivar-specific chilling and heat requirement is linked to blooming date, thus monitoring of flower bud development can provide useful information for the agricultural management and blooming time prediction.
In this study, we attempted to utilize deep learning (DL) to develop the model predicting BBCH scales of dormant flower buds.
From November to early March 2021, shoots were collected weekly from ‘Nanko’ trees and shoots bearing flower buds were video-recorded from all directions by rotating the shoots.
The image of shoot with flower buds where BBCH scale was manually annotated, were split from the videos and divided into those for training (training and validation) and test.
The effects of training parameters including stochastic gradient descent, adaptive moment estimation, and batch size, on the performance of YOLO5s model were examined and the model with the highest mean average precision value was selected as a best model.
For test images, the developed DL-based model could detect flower buds with high accuracy, while the precision values of BBCH scale classification were not high.
In conclusion, we could develop a DL-based bud detection model that can be applied for future efficient flower bud phenotyping.
However, towards a development of a model predicting bud developmental stage, further improvement, such as the dataset expansion and more refined annotation method development, is needed.
