An Experimental Study on the Effect of Cutting Angle on the Growth of Grafted Watermelon Seedlings Using the One-Cotyledon Grafting Method

The labor-efficient automation of grafting has been recognized as a key factor in the wider adoption grafting. In growing cucurbits, root pruned one-cotyledon method is most commonly used with machines. cutting angle, which affects matching rootstock and scion, to survival graft seedling. production cucurbit seedlings, parameters are established based on experience, leading low success. To determine accurate parameters, watermelon cv. ‘Zaojia84-24? was scion pumpkin ‘Zhenzhuang’ rootstock, two one-way experiments investigating angle factors were conducted. had no significant effect xylem reconnection rate or rate. A larger for led delay phloem. Different angles significantly affected growth after Compared 10° (SL), 14° (SM) 20° (SS) greater dry weights, increases 16.00% 18.61%, respectively. roots (RL), 17° (RM) 27° (RS) 29.33% 22.54%, results this study can provide reference design mechanisms robots, improving precision robots.
