Abstract

A study on the effect of interactions between paclobutrazole and KNO3 application on the quality and quantity of Dendrobium ‘Sarifah Fatimah’ orchid cutflower was conducted. The experiment was arranged in a Randomized Complete Block Design (RCBD) employing two factors, i.e. paclobutrazole doses (100, 150, 200 ppm) and KNO3 doses (100, 200, and 300 ppm), replicated three times respectively providing 27 experimental units. The results showed that paclobutrazole and KNO3 application had significant effect on the reproductive parameters. To accelarate flowering and higher quality and quantity of the flowers, paclobutrazole of 100 ppm were applied at 2 and 5 weeks after adaptation combined with KNO3 of 100 ppm applied twice at interval of 3 weeks after paclobutrazole application could be given.

Abstract

A research has been conducted to understand the responses of soybean and mungbean to the persistence of Reflex residuals in soils referring to its active substance contents, i.e. fomesafen, in the plants grown in Reflex-exposed soils. The study was carried out experimentally in glass house from June to November 2003 employing Completely Randomized Design (CRD) with treatments arranged factorial. Two factors were used, the first of which was plant species (soybean and mungbean) while the second was Reflex concentrations (0, 25, 50, 100, and 200 ppm). Each treatment combination was replicated three times. The parameters examined comprised of fomesafen contents in the seeds, number of seeds per pod,  weight of 100 seeds, and weight of total seeds. To measure fomesafen contents in the seeds, Gas Liquid Chromatograph with ECD detector and column containing 10% OV-101 chromosorb WHF 80/100 mesh of 2m lengths and 3 mm diameter was applied. Fomesafen residuals in the soils of 5 month persistence had no harmful effect on both soybean and mungbean plants. As well, they had no significant effect on the production variables of both plants. Soybean seeds planted in the 5-month Reflex-exposed soils still contained fomesafen while the corresponding mungbean seeds did not.

Abstract

The objective of this study was to determine the effect of paklopbutrazol concentration and fertilizer on plant height and flower quality of potted chrysanthemum. The experimental method was used with factorial design. The first factor was paklobutrazol with the concentration as follow:  0, 100, 200, and 300 ppm. The second factors were cow, chicken, and goat manure. Parameters observed were plant height, time of flowers emerging, flower diameter and freshness. The results showed that certain concentration of paklobutrazol might inhibited plant height, time of flowers emerging, and shortening of flowers freshness, while chicken manure fertilizer spurred flower diameter.
