Abstract

|
|
This study was carried out to search for suitable media for enhancing the growth of scale-propagated lily bulblets of ´Casa Blanca´ and ´Marco Polo´. The physio-chemical properties of media were also investigated. pH of upland soils was 7.6, and ranged between 4.0-5.4 in all other media. Organic contents were above 27.8% in all media except upland soils (4.2 %). In upland soils, bulk density was higher than the other media but water content differed. The TKS-2 + peatmoss mixture gave most vigorous shoot growth of ´Casa Blanca´ and sawdust was most effective for ´Marco Polo´. ´Casa Blanca´ grown under TKS-2 + peatmoss mixture was high in chlorophyll content of 1.40 ㎎·g^(-1). Chlorophyll content of ´Marco Polo´ grown under sawdust + TKS + peatmoss mixtures gave even higher chlorophyll content of 1.45 ㎎·g^(-1). The sawdust mixture gave lowest chlorophyll content. The sawdust + TKS mixture gave a high C/N ratio as well as contents of carbohydrate and nitrogen compound in both cultivars.
