Induction of roots on young date palm offshoots using growth regulators injection

摘要

The objective of this research was to induce root formation on young unrooted offshoots of two date palm cultivars, 'Amhate' and 'Sewy', by using growth regulator injections under greenhouse conditions. Offshoots were divided into 16 groups treated with 16 different injection treatments using 4 mL auxin solution, and then planted under greenhouse conditions. Results indicated that offshoots treated with either IBA or NAA at 3000 ppm and planted in mid-March had the highest survival percentage, both for 'Amhate' and 'Sewy'. The same treatments also improved the root number and length, and the length of developed leaves, as well.
