ABSTRACT The research was conducted at the BIH Kutagadung Berastagi Experimental Garden, Karo Regency, April-June 2021. The research aim was to determine the function of providing shelter and PGR concentration on the growth and development of chrysanthemum plantlet acclimatization. This study used a factorial randomized block design (RBD) with two treatment factors: first, containment consisted of 2 treatment levels, namely: without a cover (S0), using a plastic covers (S1). The second factor was the use of soaking time with ZPT which consisted of 4 treatment levels, namely: concentrations of 0 ml/l water (Z0), 3 cc/1 water (Z1), 6 cc/1 water (Z3), and 6 cc/l water (Z). The results showed that containment gave no significant difference (p < 0.05) in plant growth from 14 days after planting (dap) to 49 dap, stem diameter while the use of immersion time with PGR had a significantly different effect (p > 0.05) on plant height growth (56 dap and 63 dap), number of tillers and production (number of flowers per sample and flower per plot) were better than organic fertilizers. The use of long immersion with a plant growth regulator (PGR) with 6 ml/l water (Z2) was able to increase the optimum growth and production of chrysanthemum plants. The combination of the two factors tested showed no significant differences in each of the parameters observed. |
