However, contrasts showed that plants fertilized with Sierra HighN 2448 yielded more total florets than those fertilized with Osmocote 19612, particularly at the low rate. Plants fertilized with Osmocote 19612 were heavier and had more vegetative stems than those fertilized with Sierra HighN 2448 (Table 2). Fresh weight and number of vegetative stems increased with increasing rate of fertilization, with the highest response to a high rate of Osmocote 19612. At the end of the experiment, the nonfertilized plants were very small, chlorotic, and had few stems, but were still flowering. Plants that receive the low rate of either fertilizer exhibited some chlorosis on the lower leaves. Plants were smaller and produced fewer flowers in the second expriment than in the first, because the production phase was shorter and the plants wre smaller at the time of RCF application. Argo and Biernbaum (1993b) demonstrated that topdressing with medium to high rates of RCF supported continued bloom of for at least 12 weeks. Alstroemeria plants in the second expriment continued flowering for 16 weeks and plants were still producing flowering stems at the final harvest, without any fertilizer. Both experiments demonstrated that marketable potted Alstroemeria can flower for several months without the use of any fertilizer. This is in striking contrast to the results of Argo and Biernbaum (1993b), who observed a rapid decrease in flowering of unfertilized Impatiens walletiana. We suggest that this reflects the remobilization of nutrients from Alstroemeria storage roots to supported flowering. However, nonfertilized plants were much smaller than fertilized plants and extremely chlorotic, indicating inadequate nutrition in the absence of fertilization. Unfertilized plants weighed less and produced fewer vegetative stems, but not fewer floral stems, demostrating that mineral nutrition strongly influences the partitioning of assimilates into reproductive vs. vegetative growth. Minimizing the number of vegetative stems while maintaining high production of flowering stems would be desirable for Alstroemeria, especially those grown for cut flowers, because excessive vegetative stems should be removed from the plants to increase light intensity in the interior of plants (Bridgen, 1997。 Healy and Wilkins, 1991). In the first experiment, plants fertilized with RCF with an NPK ratio of=9::5 produced more flowers than those fertilized with a ratio of = 7:3:6. In the second expriment, the RCF formulation with the NPK ratio 12:: produced a greater number of florets, but plants had a lower fresh weight than the 9::5 formulation. Further research will be required to fully elucidate the effect of NPK ratio on flowering in Alstroemeria. The release time of the RCF had no effect when paring similar NPK formulations, as was observed by Argo and Biernbaum(1993b) for the postproduction performance of Impatiens walletiana. The results of this study show that fertilization is not required for postproduction flowering of potted Alstroemeria plants. However, topdressing marketable plants with RCF prevents leaf chlorosis and increases vegetative growth. Based on the results of both expriments, a medium rate of RCF, supplying N at = to ㎏ .mg3, is adequate.
