“…Suitable substrates for these plants must meet their physiological needs. Thus, substrate combinations are commonly tested and the set consisting of coconut husk, coal, and gravel is indicated as efficient for orchid cultivation (SANGHAMITRA et al, 2019). In this study, coconut substrate was the most used, mentioned as the only substrate or accompanied by others, such as gravel and coal.…”

“…Although cultivation and commercialization of these plants are predominant in the state of São Paulo, other states have increased the commercialization of orchids, such as Minas Gerais and Bahia (FARIA; COLOMBO, 2015). Therefore, proper management of orchid crops is an important factor for good plant growth and quality for trade (SANGHAMITRA et al, 2019).…”

This study investigated the profile of orchidists, their cultivation practices, and their knowledge about pests in orchid cultivation in the state of Bahia. There were applied 74 questionnaires to producers (amateurs and commercials) in 23 municipalities. The data were submitted to univariate statistics using the chi-square test, the Mann-Whitney U-test and the Kruskal-Wallis H-test. The survey shows that orchid cultivation is mostly practiced by women (67.6%) and those with higher education (48.7%). Most respondents were amateurs (87.8%). Insects (39.9%) and diseases (32.5%) were the main organisms associated with phytosanitary problems. The presence of insects was reported to occur mainly in the leaves (47%), mainly mealybugs (46.3%). Correspondence was significant between commercial and amateur groups according to the pairwise Mann-Whitney U-test (1) = 370.04 and p < 0.01. The Kruskal-Wallis H-test (27) = 924.78 and p < 0.01 discriminated categories between the groups. Despite the growing interest in orchid cultivation in the state of Bahia, most orchidists are amateurs. The study warns about the risk of pest dispersion between crops since exchanging plants and purchasing specimens in open markets are common practices.

“…Dendrobiums are epiphytic by nature and require a porous growing medium, which provides good drainage and aeration. Potting media for dendrobiums typically consists of charcoal, brick pieces, osmunda fiber, and coconut fiber in various proportions for ideal vegetative growth and flowering (Ahmad et al., 2014; Gupta & Saravanan, 2017; Hariyanto et al., 2019; Sabareeswaran et al., 2018; Sanghamitra et al., 2019a, 2019b; Srinivasulu et al., 2017). Although charcoal and osmunda fiber are good components in a growing medium, they are expensive and have typically been replaced by coconut husks (Sanguthai, 1990; Thammasiri, 2015).…”

Dendrobium, one of the largest genera of tropical orchids, is grown commercially on a large scale with an important economic impact in several ASEAN countries.Dendrobium orchids can be grown in a wide range of climates, but flower production is best under tropical conditions. Due to being the most popular orchid for cut flower production, many hybrids of Dendrobium have been produced with colorful and attractive blooms. Cut flowers of Dendrobium are popular worldwide. In addition, many Dendrobium cultivars can be grown as flowering potted plants and for other purposes such as in medicinal applications and for use in decorative products. Postharvest physiology and technology are important in maintaining the quality of both cut flowers and potted plants from production sites to the marketplace. Plants of the Dendrobium genus also contain a wide diversity of bioactive compounds that can be developed into medicinal and cosmetic products. This review describes the botany, cultivation, postharvest physiology, handling and utilization of Dendrobium.

“…In the US, Phalaenopsis is the most popular orchid, with annual production estimated to be in millions of units and revenue in the hundreds of millions of dollars. The majority of these plants are produced in vitro using plant tissue culture techniques under sterile conditions before being transplanted into suitable growth media that typically contain bark, charcoal, perlite, and/or sphagnum moss (Sanghamitra et al., 2019). Most manufacturers do not sterilize their bark mixes so that although the orchids are produced aseptically, they are exposed to fungi and bacteria upon transfer to the growth medium.…”

Diversity of unique, nonmycorrhizal endophytic fungi in cultivated Phalaenopsis orchids: A pilot study

Orchids comprise one of the largest, most diverse, and most broadly distributed families of flowering plants and contribute significantly to habitat biodiversity. One key aspect of orchid growth and development is the formation of mycorrhizal symbioses with compatible endophytic fungi, which are maintained throughout the life of the plant. Substantial efforts to identify the fungi that form mycorrhizal symbioses across a range of orchid species have often also uncovered numerous nonmycorrhizal, endophytic fungi. These fungi could also have significant effects on orchid growth and development and are beginning to be analyzed more closely, particularly in wild species. The role of endophytic fungi in the production, distribution, and continued growth by the hobbyist of orchids is not known. As an initial step toward characterizing nonmycorrhizal endophytic fungi associated with cultivated orchids, we undertook a survey of fungi residing within roots of Phalaenopsis plants growing in home environments. Sequence analysis of ITS regions amplified from total DNA isolated from roots allowed rapid identification of endophytic fungi to the class level and may offer a useful initial screening method for beneficial species, for example, in horticultural settings. ITS‐PCR sequences subsequently obtained from individual fungi cultured from surface‐sterilized orchid roots corroborated the findings of the initial screen, while also providing a more complete characterization of the array of fungal taxa that were present. Although lower in diversity than has been reported for orchids growing in the wild, these endophytes have the potential to substantially enhance the growth and disease resistance of horticultural orchids.
