Phytohormone levels in the shoot apical meristem of control and ethephon-treated plants.

	JA	JA-ILE	IAM	pTR
Control	2.23±0.42a	0.47±0.07a	1.18±0.23a	0.98±0.13a
Ethephon	1.05±0.17b	0.18±0.05b	2.63±0.54b	0.36±0.04b
Category	JA	JA	Auxin	CK

Data are means (ng/g) of three replicates±SD. Different letters indicate a significant difference between each hormone level of control plants and that of ethephon-treated plants at 5% level as determined by Duncan’s new multiple range test. JA, jasmonic acid; JA-ILE, jasmonoyl-L-isoleucine; IAM, 3-indoleacetamide; pTR, para-topolin riboside; and CK, cytokinin.
