The Physiology of Tropical Orchids in Relation to the Industry

Nutrient Concentration in Vegetative Organs of the Orchid <i>Laelia anceps</i> subsp. <i>anceps</i> Based on Mineral Fertilization and Biofertilization

“…One of the fundamental factors for mass production of orchids is a knowledge of their specific nutritional characteristics, but a lot of work is needed in terms of tissue analysis, N:P:K ratio and the nutritional requirements in different growth states (Hew and Yong, 2004) to develop specific fertilization programs.…”

“…Like other plants, orchids need several essential elements (macro and micronutrients) for normal growth, but they take longer to show mineral deficiencies, and the mineral concentration of an orchid tissue may depend on the growth medium, genus, age, and fertilization program (Hew and Yong, 2004). According to Poole and Sheehan (1982), Laeliocattleya Aconcagua and Laeliocattleya culminant display different patterns of nutrient concentrations, based on the organs of the plants.…”

<i>Gastrodia elata</i> modulates amyloid precursor protein cleavage and cognitive functions in mice

“…However, current Western methodologies need to take into consideration the complex mixture of chemicals and how they are to be used in human. The scientific proof and clinical validation of these herbal formulations require a rigorous approach that includes chemical standardization, biological assays, animal models, and clinical trials (3,4).…”

Effects of ethylene on the postharvest quality of inflorescences of Oncidium varicosum Samurai

“…For Oncidium "Goldiana" flowers, the ethylene production started after a latent period of 100 hours post harvesting and an increase in the climacteric period that formed a peak at 11 days (Hew and Yong, 2004). Ketsa and Thampitakorn (1995) The concentration of 100 μL L -1 led to a greater physiological response of the flowers, causing a pronounced reduction of the relative water content, respiratory rate increase, soluble carbohydrate content reduction, flower browning, intense flower drops and longevity reduction.…”
