Abstract

The use of eco-friendly methods in controlling pest and diseases has become an increasing concern in production system in many economically important crops, including ornamentals. The application of plant extract that has an insecticidal effect is considered as one promising alternative in reducing the negative effects of synthetic pesticides. The research was conducted to assess selected plant extracts in several concentrations against leaf miner (Lyriomyza spp.) in chrysanthemum. The experiment was carried out from January to December 2017 under plastic house conditions at the Indonesian Ornamental Crops Research Institute (IOCRI). The extracted organ of insecticidal plants regularly sprayed into chrysanthemum plants and compared with water as the controls. The results showed that the application of insecticidal plants extracts reduced attack intensity and incidence from water treatment (control). Certain treatment combinations, Chinese mahogany leaf extract at the concentration of 0.25%, C. pyrethrum petal 0.15 and 0.30%, and chinaberry leaf at 0.3, 0.35% even had 0.9-3.13% lesser attack incidences than commercial botanical insecticide Neem Plus. The respected treatments also supressed more than 62% leaf miner attacks and induced the increase of marketable flowers.

Abstract

The introduction of new varieties and production system of anthuriums has faced some problems due to the lowmultiplication rates in conventional vegetative and genotypic alteration problem in reproductive propagation. Sincethen, in vitro propagation technique became important to be investigated. The research was carried out fromSeptember 2006 to August 2007 at the Indonesian Ornamental Crops Research Institute. A complete factorialexperiment was designed to accomplish two chronological in vitro activities. The first step dealt with differentincubation sites, i.e. dark and light conditions for callus induction of three potted anthurium accessions, namelyclone no. SM. 001, cv. Alphine and cv. Bonito. The best callus obtained from the incubation treatment were then,transferred into defined media with different formulations to get free-callus plantlets in the second steps. Theresults showed that more progressive callus development from spathe explant was detected on the media ofmodified Nitsch and Nitsch + 1 mg/l 2,D + 1 mg/l Kin + 1 mg/l BA stored at dark after 60 days incubation. After 45days transferring the callus in the same media on light conditions, torpedo-shaped callus was detected. Completeplanlets were obtained after 75 days reculturing the buds in Nitsch and Nitsch medium containing 2,4 D withvarious BA concentrations. Clone SM. 001 and cv. Bonito showed higher number of visible shoot and rootdevelopments compared to cv. Alphine. In general, better shoot and root developments and higher planlets survivedafter acclimatization were observed on the BA concentrations of 2 and 3 mg/l.

Abstract

Sufficient genetic diversity is important in carnation breeding program. In vivo conservation of carnation germplasmis considered inefficient due to some technical and economical aspects. In vitro conservation was then, expectedto overcome the limitation of in vivo method. The research was conducted to find out the proper media for medium-term in vitro conservation of several carnation accessions in low temperature storage. A complete factorialexperiment with 25 replications was designed to accomplish the combination of two factors. The first factor wassix commercial carnation cultivars, namely Pink Maladi, Orange Triumph, Opera, Tundra, Yellow Liberty and PradoReffit. The second factor was the conservation media i.e. 1⁄2MS + DMSO 3% and 1⁄2MS + 3% DMSO + 3% sucrose andcontrol (MS 0+3% sucrose). The results showed that in vitro conservation of carnation in low temperature weresuccessfully conducted using 1⁄2MS+3% DMSO and 1⁄2MS+3% DMSO+3% sucrose without significant variation in allaccessions tested up to 10 and 12 months respectively. The increase of death plantlets, however, was detected onthe media of 1⁄2MS+3% DMSO after 6 months storage with significant decrease in viability hereafter. The existenceof sucrose in DMSO media induced root formation and plantlet resistance to low temperature storage.

Abstract

In vitro conservation is recognized as one promising tool in conserving plant genetic resources like gladiolus when grown in the tropics. The study was conducted at the Indonesian Ornamental Crops Research Institute (IOCRI) from February 2016 to August 2018. A complete factorial experiment was set up to establish the combination of gladiolus cultivars and media compositions treatments for in vitro conservation. The results showed that the trends of plantlet survival rate and viability in every 4 months’ observation of both cultivars were similar. The highest plantlet death rate was detected during 12 – 16 months. After 24 months of storage, the differences in plantlet survival and viability were observed. Gladiolus ‘Nafa’ had higher plantlet survivals and viability than ‘Kaifa’. In respect to nutrient and sucrose concentration, full nutrient strength preserved 5% higher plantlet survival and viability than ½ MS. While media contained sucrose 90 g/l also supported plantlet survival and viability for more than 20% and 17%, respectively than lower sucrose media.

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.
