“…Under such favorable condition, the plant was provided sufficient air and oxygen for cell respiration during the rooting process (Frenck and Kim 1995). The moisture in smaller pores served not only for metabolic activities but also provided sufficient humidity to avoid excessive transpiration (Karlsen 1997) and destructive temperature fluctuation that may happen in the rhizosphere (Klapwijk 1987). Values followed by different letters in the same column differ significantly at LSD 5%.…”

Physiological status of chrysanthemum cuttings during rooting process highly influences plant growth and flower production. Amongst other aspects, rooting capacity of the cuttings is the most important. Rooting capacity is influenced by environmental conditions such as growing medium and nutrition. The study was aimed to analyze the effects of different types of media, fertilizer concentration, and frequency of fertilizer application on the rooting capacity of chrysanthemum cuttings. The experiment was conducted at the Segunung Experimental Station of the Indonesian Ornamental Crops Research Institute from February to May 2005. The treatments consisted of four different rooting media, i.e. carbonized rice husk, coco peat, perlite, and mixture of perlite and vermiculite (1:1 v/v); two concentrations of NPK (25:7:7) fertilizers, i.e. 1.75 and 2.5 g 1-l; and four frequencies of fertilizer application, i.e. every 1 day, 2 days, 3 days, and 4 days. The experiment was designed in a completely randomized block with four replications. Parameters observed were rooting capacity and cutting performances such as cutting height, cutting diameter, number of leaves, number of visible roots, and root length at 16 days after planting. The results showed that chrysanthemum cuttings rooted in carbonized rice husk had better performance than those rooted in coco peat, vermiculite, and mixture of perlite + vermiculite. Higher concentration of fertilizer solution up to 2.5 g l-1 also gave significant effect on the root formation and further root growth of cuttings. However, the rooting capacity of cuttings was not affected by the frequency of fertilizer application. This study implied that carbonized rice husk growing medium supplemented with NPK (2.5 g l-l) every 4 days during rooting period is the choice for traditional chrysanthemum growers to increase the perform-ance and quality of the cut flowers.

“…tant not only for plant uptake in metabolic activities, but it also provided more favorable condi-tions in the root environment (Karlsen and Bertram 1995) as well as less destructive temperature fluctua-tion in the soil (Klapwijk 1987), since June to October, the experimental sites were in dry season. Worse growth performance of the plants treated with twice per week irrigation was predictably caused by inconstant water availability in the root system.…”

Chrysanthemum is one of important ornamentals in Indonesia and it ranks in the first quantity of cut flower marketed every year. In most cases, the low productivity is still a constraint for the traditional growers to make production process profitable. Several problems revealed in chrysanthemum production were investigated. The study dealt with the effect of two types of plastic house constructions, irrigation frequency, and leaf detachment on the growth and development of chrysanthemum. The experiment was conducted at Segunung, Indonesian Ornamental Plants Research Institute during the dry season of 2005. A nested design with six replications was used. The results showed that plants grown in wood-constructed plastic house had better growth performance and flower quality than those under bamboo plastic house. Longer stem and higher plant fresh weight with more flowers and longer life span were also observed on chrysanthemum irrigated four times per week than those irrigated twice per week. Leaf removal often practiced by the growers is no longer recommended, since the number of leaves on the plant influenced all parameters observed. The more leaves were detached, the more negative impacts on plant growth were found.

“…The four times per week irrigation seemed to have supplied the roots with more constant moisture content. This water content was impor- tant not only for plant uptake in metabolic activities, but it also provided more favorable condi-tions in the root environment (Karlsen and Bertram 1995) as well as less destructive temperature fluctua-tion in the soil (Klapwijk 1987), since June to October, the experimental sites were in dry season.
