Effect of microclimate and photosynthesis on strawberry reproductive growth in a greenhouse: using cumulative leaf photosynthesis as an index to predict the time of harvest
We evaluate whether cumulative photosynthesis (An,C) could predict the time of harvest in strawberry better than light (IC) or temperature (Ta,C) as forecast indices. We monitored the daily dynamics of flowering, fruit set, and harvest in over 2,700 fruits across the growing season in a greenhouse in Japan. Photosynthesis was calculated using a biochemical model, and An,C calculated by totalling the cumulative rate from flowering to harvest in each fruit. IC and Ta,C were calculated by totalling daily cumulative light intensity and average temperature. A new index (D) was defined as the normalised variation of An,C, IC, and Ta,C, and a statistical analysis was conducted on the means for each index. The results showed that An,C had the lowest D (0.114), suggesting that it was a better index for predicting the time of harvest. This study suggests the importance of considering the accumulation of photosynthates in individual fruit, which cannot be achieved by IC or Ta,C, these results can be used to improve the forecasting and optimisation of yield. However, further research is required to substantiate these claims.
期刊介绍:
The Journal of Horticultural Science and Biotechnology is an international, peer-reviewed journal, which publishes original research contributions into the production, improvement and utilisation of horticultural crops. It aims to provide scientific knowledge of interest to those engaged in scientific research and the practice of horticulture. The scope of the journal includes studies on fruit and other perennial crops, vegetables and ornamentals grown in temperate or tropical regions and their use in commercial, amenity or urban horticulture. Papers, including reviews, that give new insights into plant and crop growth, yield, quality and response to the environment, are welcome, including those arising from technological innovation and developments in crop genome sequencing and other biotechnological advances.
