The Mineral Nutrient Requirements of Forest Trees

Indoleacetaldehyde in Cucumber Seedlings 1

The presence of indoleacetaldehyde in cucumber (Cucumis sativus L.) cotyledons was demonstrated by thin layer chromatographic RF values in three solvent systems, by the formation and hydrolysis of a bisuulfte adduct, and by chemical reduction to indoleethanol and oxidation to indoleacetic acid. Bioasys indicated a minimum indoleacetaldebyde content in etiolated cotyledons of 0.7 lg per kg fresh...

Combined Inoculation with Multiple Arbuscular Mycorrhizal Fungi Improves Growth, Nutrient Uptake and Photosynthesis in Cucumber Seedlings

Mycorrhizal inoculation stimulates growth, photosynthesis and nutrient uptake in a wide range of host plants. However, the ultimate effects of arbuscular mycorrhyzal (AM) symbiosis vary with the plants and fungal species involved in the association. Therefore, identification of the appropriate combinations of AM fungi (AMF) that interact synergistically to improve their benefits is of high sign...

Trace Mineral Requirements for Dairy Cattle

A host of nutrients are needed by cattle to support functions associated with life, and to grow, reproduce, and nourish their offspring (i.e., produce milk). A vast amount of resources have been expended to quantify the amounts of specific nutrients needed to perform these function so that economically efficient diets can be formulated. Feeding diets that provide adequate, but not excessive, am...

Nutrient Profiling – Mineral Supplementation

An animal’s requirements for TM begin while it is in utero, as TM are essential for proper embryonic development and survival (Ashworth and Antipatis, 2001; Hostetler et al., 2003). Moreover, TM deficiencies of the developing fetus carry over into the postnatal period with lesser TM storage in tissues of the neonates, further limiting neonatal growth, development, performance and immunity. Duri...
