Values followed by different letters within columns are significantly different at the 0.05 probability level. III: the thirdh primary tiller; I-p: the first secondary tiller from I; IV: the fourth primary tiller; I-1: the second secondary tiller from I; II-p: the secondary tiller from II. CK: deionized water was sprayed on the plants. I30, I60, and I90 denote 30, 60, and 90 mg L-1 IAA was sprayed on the plants, respectively. Z30, Z60, and Z90 denote 30, 60, and 90 mg L-1 Z was sprayed on the plants, respectively (n = 30).
