Abstract Ornamental industry has applied immensely in species used in interior landscapes are: Dieffenbachia vitro propagation approach for large-scale plant maculate (syn. D. picta), D. amoena, D. seguine. multiplication at very high rates of elite superior varieties. As Dieffenbachia has been produced as an ornamental foliage a result, hundreds of plant tissue culture laboratories have plant for interiorescaping since 1864 [6, 7] and consistently come up worldwide. Dieffenbachia species are popular ranks among the top five most popular foliage plant genera foliage potted plants used in interiorescapes of homes, based on annual wholesale value [7, 8]. Moreover, the offices, and malls throughout the world. Most of number of Dieffenbachia cultivars increased form 7 in 1975 Dieffenbachia species are now propagated by tissue culture to 23 cultivars by 1999 [8]. In addition to its character as for better utilize of species and expedite plant improvement. ornamental plant, this genus also reported to be used in This review paper summarizes valuable literature on in vitro biological control of some pests [9, 10] and as medicinal techniques including type of explants used, media optimized, plant [11], since all parts of Dieffenbachia is poisonous and ways of propagation and improvement through 45 years of can be a source of antimicrobial activities [12]. research on Dieffenbachia spp. Which were provide basis for Dieffenbachia conventionally propagated by seed, tip or future studies such as genetic transformation for breeding cane cuttings, division and air layering. Seed is not aims, develop new cultivars, develop disease-resistant plants commonly used except in breeding because it does not and overcome the environmental obstacles. There is a need encourage the expansion of the species, moreover, seed for more application of the plant tissue culture techniques on production is limited [13, 14]. Conventional methods are Dieffenbachia to investigate the responses of different very slow moreover, ex vitro vegetative propagation of cultivars and explants to variable culture media. Dieffenbachia is hampered by endogenous bacteria infection leads to total loss of vegetative parts [15, 16]. Besides Keywords Dieffenbachia, Review, Tissue culture, conventional methods of propagation in vitro Multiplication, Indirect regeneration micropropagation contributed very much in the propagation of Dieffenbachia. In vitro techniques offers many unique advantages over conventional propagation methods such as disinfection, rapid multiplication of valuable genotypes, 1. Introduction expeditious release of improved varieties, production of The genus Dieffenbachia consists of about 30 species and disease-free plants, non-seasonal production and facilitating over 100 cultivars with spotted, striped or speckled with their easy international exchange [17]. The main objective of cream, white, yellow, gold, silver, or a combination of these this article is to overview literature covering the previously colors leaves, 15 to 40 cm or so in length [1, 2]. work done on Dieffenbachia tissue culture from 1976 until Dieffenbachia is an ornamental perennial monocot plant 2011, and brings forth some points that we consider as the native to tropical America [3], belonging to the family major thrust of contemporary and future research. However, Araceae [4]. It is prized among interiorscapers for the the works on Dieffenbachia is summarized in Table1. Figure attractive variegated foliage, tolerance of interior 1 illustrated general scheme for in vitro micropropagation environments and easy production [5].
