We elucidate grapevine evolution and domestication histories with 3525 cultivated wild accessions worldwide. In the Pleistocene, harsh climate drove separation of grape ecotypes caused by continuous habitat fragmentation. Then, occurred concurrently about 11,000 years ago in Western Asia Caucasus to yield table wine grapevines. The domesticates dispersed into Europe early farmers, introgressed ancient western ecotypes, subsequently diversified along human migration trails muscat unique...
Abstract In this article, the relationship between fluorescence characteristics of leaves different grape varieties (electron transport intensity photosystems – ETR and variable Fv) relative water content (RWC) in was studied. It found that more drought-resistant variety is, slower decrease value with RWC reduction. According to Fv, we can estimate degree damage photosynthetic apparatus as a result deficiency, i.e., how irreversible is caused by drought? obtained results, when decreases from...
