Increases in demand for fruit of Morinda citrifolia in recent years have led to commercial farming of the trees. Typically as a crop makes the transition from wild-harvested to commercial orchard, there is a concurrent effort to select more desirable varieties and to improve the crop. In order to make these selections and improve the crop, researchers must know about the diversity found within ...

Monovarietal virgin olive oils (VOOs) are very effective to study relationships among sensory attributes, the compounds responsible for flavour, and factors affecting them. The stimulation of the human sensory receptors by volatile and non-volatile compounds present in monovarietal virgin olive oils gives rise to the sensory attributes that describe their peculiar delicate and fragrant flavours...

The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit ⁄yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contributed to the genetic improvement of wheat, using va...

The isolation from bud scales and partial characterisation of highly active, low molecular weight, germination inhibitors, in concentrations correlated quantitively with resistance of N52/219, N11, NCo376, and NCo293, holds promise for the development of a rapid, quantitative, chemical assay for evaluating sugarcane for pre-infectional resistance to smut. Histopathological studies on stalk and ...

• The concentration of anthocyanins in grape skins is a characteristic specific to each grape variety even if environmental and cultural factors play a role in determining the final amounts. Knowing the anthocyanin characteristics of grapes before harvest would allow the winemaker to choose the maceration regime best suited to maximize the potential of each incoming grape load. The initial goal...

We describe the structure of those locally finite varieties whose first order theory is decidable. A variety is a class of universal algebras defined by a set of equations. Such a class is said to be locally finite if every finitely generated member of the class is finite. It turns out that in order for such a variety to have a decidable theory it must decompose into the varietal product of thr...

Dominions, in the sense of Isbell, are investigated in the context of decomposable varieties of groups. An upper and lower bound for dominions in such a variety is given in terms of the two varietal factors, and the internal structure of the group being analyzed. Finally, the following result is established: If a variety N has instances of nontrivial dominions, then for any proper subvariety Q ...

A full characterization of when a subgroup H of a group G in a varietal product NQ is epimorphically embedded in G (in the variety NQ ) is given. From this, a result of S. McKay is derived , which states that if NQ has instances of nonsurjective epimorphisms, then N also has instances of nonsurjective epimorphisms. Two partial converses to McKay’s result are also given: when G is a finite nonab...

The 2-category VAR of finitary varieties is not varietal over CAT . We introduce the concept of an algebraically exact category and prove that the 2-category ALG of all algebraically exact categories is an equational hull of VAR w.r.t. all operations with rank. Every algebraically exact category K is complete, exact, and has filtered colimits which (a) commute with finite limits and (b) distrib...
