Comparison of Different Media to Produce Cymbidium Orchids by Pseudobulbs

Abstract

Nowadays, Orchids are one of the most commercial products in flower markets. One of the propagation methods for Cymbidium is using old pseudobulbs that are thrown out after flowering period. This research carried out using standard Cymbidium back-bulbs based on randomized complete block design with 5 treatments in 3 replications. The trial traits were leaf length, root length, leaf number and root number that were studied for 180 days. The results show that minimum length of root was significant under different growth beds. The minimum percent of rooting was observed in pure sand treatment. The maximum length was observed in pure perlite. The shortest of leaves were gained in perlite + sand treatment and the maximum leaf length was observed in pure perlite treatment. The maximum average of root percent was seen in pure perlite treatment.

A chromosome‐scale genome assembly and annotation of the spring orchid (Cymbidium goeringii)

“…The Orchidaceae consists of over 25,000 species in approximately 800 genera and is one of the largest and most widespread flowering plant families (Sedaghathoor et al, 2017; Wu et al, 2009). Orchids have been preferred for horticultural purposes in many cultures for a long time and cultivation of Cymbidium has been traced back to the 10th century in China (Hew, 2001).…”

Fertilization methods and substrate particle size differentially affect growth and macronutrient status of Laelia anceps subsp. anceps

“…In Phalaenopsis 'Stripe' and 'White Red Lip', positive results in number of roots, total fresh weight and percentage of dry matter were found when using a mixture of perlite + expanded clayball + peat moss (Hwang and Jeong, 2007). In Cymbidium orchids, number and length of roots, as well as leaf length increased with the use of perlite alone or in combination with sand or coconut peat (Sedaghathoor et al, 2017). In Phalaenopsis 'Taisuco Kochdian', growth and flowering characteristics improved with the combination of pine bark with perlite and peat moss, adding a dose of 300 mg K L -1 (Wang, 2007).…”
