C02-enhanced Foliar Deformation of Tomato: Relationship to Foliar Starch Concentration

Changes in foliar proline concentration of osmotically stressed barley.

The amino acid proline is accumulated in plant tissues in response to a variety of stresses. The existence of two routes for its biosynthesis is well documented. However, little is known about the contribution of each pathway to the accumulation of free proline under stress conditions. In the present study young barley plants were subjected to osmotic stress by treating their roots with 25% pol...

Foliar Fertilization of Soybeans

Extensive research addressed foliar fertilization of soybeans at reproductive stages during the 70s and 80s. The soybean plant has been characterized by markedly reduced root activity during late seed development and increased translocation of nutrients and metabolites from other tissue into the seed. This depletion of nutrients from leaves could result in decreased photosynthesis, leaf senesce...

Foliar release of dimethylsulfonioproprionate

We report here that substantial quantities of dissolved dimethylsulfonioproprionate (DMSP) are released from live leaves of Spartina alterniflora in Georgia, USA salt marshes during tidal submergence. Mean monthly in situ foliar release rates varied from 0.092 2 0.050 to 0.291 f 0.289 pm01 DMSP (g dry wt)-' h-'. Estimates of tidal release of DMSP from creekbank stands of S. alterniflora varied ...

Foliar Feeding Cotton

There seems to be conflicting information about foliar fertilizers and their timing of application to cotton. Much of the confusion lies in the variety of fertilizer products available. A cotton fanner now has a choice of applying foliar fertilizers (according to fertilizer labels) beginning at the first true leaf stage and continuing until defoliation. This newsletter will focus on available i...
