AI Article Synopsis
- A study investigated the impact of auxin treatment on calcium transport in apple fruit stalks, finding that different auxin concentrations affected calcium content and fruit quality.
- Results showed a significant decrease in total calcium in the stalk, alongside a 30% increase in calcium content in the fruit, suggesting auxin promotes better fruit nutrition.
- The research utilized the TOPSIS method to rank fruit quality based on auxin treatments, highlighting the potential for improved calcium efficiency in bagged apples and setting the stage for future investigations.
Article Abstract
In apples, a bottleneck effect in calcium (Ca) transport within fruit stalk has been observed. To elucidate that how auxin affects Ca forms and distribution in the apple fruit stalk, we investigated the effects of different concentrations of auxin treatment (0, 10, 20, and 30 mg·L) on Ca content, forms, distribution, and fruit quality during later stages of fruit expansion. The results showed that auxin treatment led to a dramatic reduction in total Ca content in stalk, while an approximately 30 % increase in fruit. Furthermore, auxin treatment effectively enhanced the functionality of xylem vessels in vascular bundles of the stalk in bagged apples. Finally, TOPSIS method was used to assess fruit quality, with treatments ranked as follows: IAA20 > NAA20 > IAA30 > IAA10 > CK > NPA. The findings lay a foundation for further studies on the bottleneck in Ca transport within stalk, uneven distribution of Ca in fruit, and provide insights into Ca utilization efficiency in bagged apples.
