Data Sheet 2_Field evaluation of ascorbic acid seed priming on growth, physiology, yield, and nutritional quality of broccoli (Brassica oleracea L. var. italica ‘Gypsy’).csv
Listed in figshare
<p>Seed priming with ascorbic acid (AsA) has been widely recognized for enhancing early plant development; however, its effectiveness in improving growth, physiology, yield, and nutritional quality of broccoli under field conditions remains limited.
Description
This two-year field study evaluated the effects of AsA seed priming on broccoli under Atlantic Canada soil conditions using a randomized complete block design across two field sites.
Four treatments were assessed: non-primed control, water-primed (0 mgL<sup>-1</sup>), and AsA-primed seeds at 1 mgL<sup>-1</sup> and 10 mgL<sup>-1</sup>. AsA priming significantly (p < 0.05) enhanced plant height, canopy length, stem girth, and leaf area, with the greatest improvements observed at 10 mgL<sup>-1</sup>, resulting in increases of 17.4%, 19.7%, 51.7%, and 69.4%, respectively, compared to the control. Net photosynthesis, stomatal conductance, transpiration, and chlorophyll index, were also significantly improved (p < 0.001).

Biochemical analysis showed significant increases (p < 0.05) in chlorophyll a and carotenoid content at 10 mgL<sup>-1</sup>. Meanwhile phenolics, flavonoids, and most nutrients were not significantly affected (p ≥ 0.05), except for a slight but significant (p < 0.05) reduction in phosphorus concentration at 10 mgL<sup>-1</sup>. Yield components were significantly (p < 0.05) improved by AsA priming, with 10 mgL<sup>-1</sup> increasing primary yield by 38.4% and secondary yield by 80.4%, whereas 1 mgL<sup>-1</sup> significantly (p < 0.05) increased the number of secondary heads per plant by 15.3% compared with the control.
Overall, AsA seed priming enhanced growth, physiological performance, and yield without compromising nutritional quality, demonstrating its potential as a practical and sustainable approach to improve broccoli production under field conditions.</p>
