Nutrient Solutions for Orchids

Nutrient Solutions for Hydroponic Systems

Among factors affecting hydroponic production systems, the nutrient solution is considered to be one of the most important determining factors of crop yield and quality. This chapter aims to explain aspects related to plant nutrition and its effects on production of hydroponic crops, considering basic aspects such as nutrient solutions and their development through the years; components of nutr...

Orchids

aperture in the tissues surrounding the meristems. 'This simple experiment revealed that there were four distinct regions of the embryo with different plasmodesmata apertures. The shoot meristem had the highest aperture enabling movement of single-to-triple sized GFP; the hypocotyl (embryonic stem) allowed single, double and some triple-sized GFP movement; the root allowed single and double-siz...

Limited carbon and mineral nutrient gain from mycorrhizal fungi by adult Australian orchids.

PREMISE OF THE STUDY In addition to autotrophic and fully mycoheterotrophic representatives, the orchid family comprises species that at maturity obtain C and N partially from fungal sources. These partial mycoheterotrophs are often associated with fungi that simultaneously form ectomycorrhizas with trees. This study investigates mycorrhizal nutrition for orchids from the southwestern Australia...

Chelation of Trace Metals in Nutrient Solutions.

Plant nutrition studies frequently require nearly complete elimination of trace metals from the nutrient media in which the plants are to be grown. Conventional methods of purification by recrystallization and precipitation have been used for this purpose in some studies. These have proved more difficult and less effective than the adsorption technique developed by STEINBERG (11) and improved b...
