In botany, a pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. Some orchids have pseudobulbs (e.g. Cattleya, Bulbophyllum, etc.), and others don’t (e.g. Phalaenopsis, Habenaria, Cochleanthes, etc.). Of the orchids that have pseudobulbs... Pseudobulbinorchids grow from a horizontal stem that grows underneath the planting medium. These stems travel underground and the pseudobulbs pop up along the length. Pseudobulbs are equally important structures in C3 and CAM orchid taxa, and may function similarly in water, carbohydrates, and (or) essential elements storage in the two groups of orchids. Understanding these pseudobulbs and how to maintain them is a key element in caring for these types of orchids. We link to vendors to help you find relevant products. The green pseudobulbs of epiphytic orchids function as storage organs for water, mineral and carbohydrates. They are responsible for the ultimate re-distribution of assimilated carbon... They help an orchid survive through dry seasons. In addition, new orchids can be propagated through pseudobulb division. Pseudobulbs can become wrinkled if the orchid is under-watered. Epiphyte Pseudobulbs Examples. Types of epiphytic orchids that have pseudobulbs include the genera Cattleya, Dendrobium and Oncidium. As storage organs for water and nutrients, pseudobulbs play an important role in the survival of orchids. However, the differences in morphological and physiological responses of... Pseudobulbs, which are somewhat enlarged or thickened succulent stems, are common in epiphytic orchids. Nitrogen can be transported from old to young pseudobulbs and between... Sympodial orchids (Cattleya and Cymbidium) develop pseudobulbs along low-growing rhizomes that can be split to grow independently. PseudobulbinOrchids#. Orchids with pseudobulbs, which are a good number of the most common orchids grown in homes, may include: Cattleya Dendrobium Epidendrum Laelia Oncidium. In this study, nitrogen allocation to each organ and nitrogen resorption of Pleione aurita, an epiphytic orchid characterized by annually renewed pseudobulbs... In the Black Orchids (Bulbophyllum), the pseudobulbs are no longer than 2 millimeters. The largest orchid in the world, the Giant Orchid (Grammatophyllum speciosum), has pseudobulbs...
