摘要: Unbranched rooted layers of the rootstock Mailing 9 (M.9 clone Nie 29) ≈600 mm long were treated twice in autumn (4 and 13 October 1995) stoolbed as follows: a) non-treated control; b) distal 300 shoot was painted with an aqueous solution TIBA [250 mg 1−1 2,3,5-triiodo-benzoic acid 2 ml l−1 Tensospray wetting agent (100 g alkyl-aryl-polyethyleneglycol)]; c) proximal ®300 Promalin® (3000 N-(phenylmethyl)-1H-purine 6-amine 3000 gibberellins A4+A7 without a agent); d) above Promalin treatments combined on same shoot. Twenty stoolshoots per treatment forced 20 1995 (autumn), 5 December (mid-winter), 21 February 1996 (late winter).
