Abstract

The longer vase life of chrysanthemum cut flower is one of the preferable quality traits in marketing for growers, retailers and consumers.  Several compounds, like ascorbic acid, have been reported to be able to prolong the post-harvest quality and longevity of cut flowers. Thus, the purpose of the study was to assess the ascorbic acid effects in several concentrations (0, 100, 200, and 300 ppm) in extending the fresh life of two chrysanthemum cultivars, i.e. cv. Remix (spray) and Yellow Fiji (standard).  The results showed that the termination of flower freshness was visually characterized by wilting of leaves and florets and the change in floret color (paler).  The supplementation of ascorbic acid solution at the concentrations of 200 and 300 ppm prevented and lengthened leaves and florets turgidity and postponed the wilting up to 2 – 3 days compared to control.  At the same concentrations, the solution also slowed down the degradation rates of chlorophyll content on leaves during vase life periods.

Abstract

 In vitro technique was dedicated to alleviate the technical problems in conventional propagation of gladiolus for healthy planting material production in marketable quantities.  Two experimental series were conducted in non factorial and factorial designs respectively.  Cormels of three gladiolus cultivars namely Kaifa, Clara and Nabila were inoculated into free hormone media for plantlet establishment and dormancy breaking observations among genotypes.  The established plantlets were then deflasked into solidified MS + 0.5 mg/l NAA with various BA concentrations (1, 2, 3 and 4 mg/l).  A randomized complete experiment with seven replications was designed to accomplish these subsequent experiment to determine optimal BA for shoot-leaves initiations and complete plantlet formations. The results showed that in free hormone media, the dormancy breakings of cormel were varied among cultivars tested.  The variation among cultivars was also detected on the level of BA for optimum shoot and leaf formations.  2 mg/l BA gave highest shoot and leaves formations for cv. Nabila while higher concentrations needed by other two cultivars. Thus, BA concentrations ranged from 2–3 mg/l were recommended shoot inductions on in vitro propagation of gladiolus.

Abstract

An evaluation of formulated Bio-PF with the active ingredient of Pseudomonas fluorescens to reduce synthetic fungicide usage in controlling soil borne disease in leather leaf fern under different shelters was studied. The research was conducted at the experimental field of the Indonesian Ornamental Crops Research Institute (IOCRI) from January to December 2015. Different concentrations of Bio-PF were singly and/nor alternately applied with two different synthetic fungicides were applied on leather leaf plants under UV plastic + 70% black-net and 70% black-net shelters. The results showed that the average disease intensity was higher in 70% black-net shelter. Weekly alternate-application of Bio-PF 5 + Carbendazim & Mancozeb and single Carbendazim & Mancozeb gave lower disease intensity than other treatments with the highest percentage of suppression. These two treatments also improved yield in terms of number and proportion of the preferred grade of harvested leaves. Combined Bio-PF 5 + Carbendazim & Mancozeb gave longer vase life and the application reduced synthetic fungicide usage in controlling the respected disease. In term of synthetic fungicides, Carbendazim & Mancozeb gave more consistent effects on disease suppression, plant growth and foliage production than Asilbensolar & Mancozeb.
