Effect of growth regulators on yield and fiber quality in ramie ( Boemheria nivea (L.) Gaud.), China grass
The effects of two mixtures of four plant growth regulators (choline chloride, gibberellin (GA 3), benzyladenine (6-BA) and NaHSO 3) at 20:9:5:800 mg kg −1 (H1) and 20:42:43:2350 mg kg −1 (H3) (active ingredients), respectively, were investigated on yield and fiber quality in ramie ( Boehmeria nivea...

−1 (H3) (active ingredients), respectively, were investigated on yield and fiber quality in ramie (
Boehmeria nivea (L.) Gaud.). The mixtures were sprayed over the canopy at two growth stages (10 and 20 days after the previous cut) of field-grown ramie. The treatments increased raw fiber yield by 13–18%, and improved fiber fineness by 57–349

−1, increased number of leaves per plant, and also improved all yield components. Treatment H1 resulted in a denser distribution, smaller diameters and greater quantity of fiber cells in stem cross-section. Physiological responses included improving leaf water status, increasing net photosynthetic rate, and decreasing electrolyte exosmosis rate. |
