Previous investigational work on the nutrition on the strawberry has been concerned largely with the relationship of soil and fertilizer treatment to growth and yield (5). While these studies have increased greatly the knowledge of the fertilizer requirements of the strawberry, they did not describe the symptoms of mineral deficiencies nor show the mineral composition of the plant and fruit. It...

Mineral nutrients taken up by the roots are, as a rule, transported in the xylem to the shoot, and photoassimilates transported in the phloem to the roots. According to the Thornley model of photosynthate partitioning, nutrient deficiencies should favour photosynthate partitioning to the roots. Examples are cited to show that this preferential partitioning is dependent on phloem mobility and he...

ied in the central and south part of the western San Joaquin Valley of California. Alluvial deposits in the Despite extensive research on B adsorption and release from soils, valley derive primarily from Coast Ranges of California, mineral sources of B within natively high B soils remain poorly understood. The objectives of this study were to identify source minerals which are composed of sever...

We characterized the adventitious rooting response of Eucalyptus globulus Labill. to various concentrations of calcium, nitrogen, phosphorus, iron, manganese, zinc, boron and copper. The parameters analyzed were percent rooting, root number, root length and mean rooting time. Root number and root length were significantly affected by mineral nutrition, whereas mean rooting time and rooting perc...

Organic dairy farmers often introduce alternative pasture species, such as chicory (Cichorium intybus) and narrow-leaved plantain (Plantago lanceolata), to their swards because of their higher mineral contents, yet they are concerned about the presence of weed species such as docks (Rumex spp.) and dandelion (Taraxacum officinale). The mineral content and nutritive value of both desired and les...

A series of novel, dinuclear (2,2':6',2''-terpyridine)platinum(ii) complexes containing bis(thioalkyl)-dicarba-closo-dodecaborane(12)(carborane) ligands were prepared and characterised, and their preliminary anti-cancer characteristics have been determined in vitro; the complexes are the first examples of bis-intercalator complexes containing a boron-rich carborane cage.

The conjugated aromatic system of graphene was used to trap the reactive, boron-rich 1,2-carborane cluster. Functionalization of the graphene surface was confirmed by solid-state MAS (11)B NMR spectroscopy and quantified by X-ray photoelectron spectroscopy. This work represents the first confirmed example of direct functionalization of a graphene lattice with carboranes.
