Reducing the sink/source ratio of On-date palm plants during fruit growth has physiological and biochemical impacts on the shift in source-sink limitations.

At Rutab, thinning types demonstrated the source limitation of On-trees. Bunch removal and bunch thinning by removing the source-sink limitation had the greatest effect on increasing yield components and fruit size, respectively. To improve the quality and quantity of fruit, it's important to use both thinning techniques simultaneously. This article is protected by copyright. All rights reserved.
