Background. Grapevine leafroll disease is one of the most widespread viral diseases in vineyards, affecting nearly all grape and wine regions in the world. Infection causes yield losses, ripening delays, and alters fruit chemistry, including lowering soluble solids and increasing titratable acidity. The viruses associated with leafroll disease are transmitted through propagation of infected mat...

More than 100 years ago a grapevine disease of unknown etiology was recognized in France and California, where it was called “folletage” (Ravaz, 1898) and “sunstroke” respectively (Anonymous, 1895). In both cases the disorder was considered to be due to a physiological condition resulting from what was called “abrupt changes in the bottom water level.” Research on the pathological nature of the...

We present a new methodology for selecting a Bayesian network for continuous data outside the widely used class of multivariate normal distributions. The use of bivariate copula densities to model connections between pairs of nodes in the network brings in flexibility in the choice of the distribution. Cand D-vines play a central role in dealing with the high-dimensional aspect of the data, due...

This article considers the main parameters of experimental rotary working body (RWB) used for tillage and opening buried vines in protection zone between rows, soil loosening weeding blades crop zone, as well number paddles vines. The performance indicators largely depend on its kinematic mode operation, knives, dumps picks. destruction weeds root movement required volume towards row spacing is...

The tree tomato (Solanum betaceum Cav.) is an underutilized fruit crop native to the Andean region and phylogenetically related potato. Tree fruits have a high amount of nutrients bioactive compounds. However, so far there are no studies at genome or transcriptome level for this species. We performed de novo assembly annotation purple-fruited (A21) orange-fruited (A23) accessions. A total 174,2...
