First Results on the Rio-Agronomic Behaviour of Six "Sangiovese" Clones in the "Morellino di Scansano" Wine Doc Production Zone. Choice of clone represents a cru¬cial technical aspect in setting up new vineyards. Clonal selection car¬ried out on "Sangiovese" during the last twenty years has provided grapevine-growers with a wide range of genetic material from which to choose. However, when operating within a specific vine¬yard, it is still difficult today to sin¬gle out the most appropriate clone for the given situation, since knowl¬edge on the vegetal-productive and qualitative behaviour of commer¬cially available clones is so far insuf¬ficient. A series of bio-agronomic observations was therefore under¬taken on six "Sangiovese" clones in one of the classic grapevine-growing areas of the Province of Grosseto, the Doc "Morellino di Scansano" production area. An experimental vineyard was set up with the follow¬ing' clones: SS-F9-A5-48, M42, Peccioli 1, R24, VCR4, R1O. The grapevines were established in win¬ter 1994 as cuttings grafted onto 420A, spaced at 3 x 1 m and trained to espalier with horizontal single cordon. Results obtained from observations on vegetal-pro-ductive parameters and must qual¬itative characteristics highlight a number of interesting behavioural differences between the clones exam¬ined. Briefly, quantity of grapes per grapevine was greatest in clones SS-F9-A5-48 and lowest in R1O, sugar concentration was highest in clones M42 and Peccioli 1, and polyphenol and anthocyanin levels highest in clones Peccioli 1 and SS-F9-A5-48. These results obtained from the first cycle of observations should be con¬sidered merely preliminary. Further research will be required in future years in order to obtain a sufficient number of values from adult grapevines before the outcome of research can be translated into practical applications available to wine estates.

Abstract
First Results on the Rio-Agronomic Behaviour of Six "Sangiovese" Clones in the "Morellino di Scansano" Wine Doc Production Zone. Choice of clone represents a cru¬cial technical aspect in setting up new vineyards. Clonal selection car¬ried out on "Sangiovese" during the last twenty years has provided grapevine-growers with a wide range of genetic material from which to choose. However, when operating within a specific vine¬yard, it is still difficult today to sin¬gle out the most appropriate clone for the given situation, since knowl¬edge on the vegetal-productive and qualitative behaviour of commer¬cially available clones is so far insuf¬ficient. A series of bio-agronomic observations was therefore under¬taken on six "Sangiovese" clones in one of the classic grapevine-growing areas of the Province of Grosseto, the Doc "Morellino di Scansano" production area. An experimental vineyard was set up with the follow¬ing' clones: SS-F9-A5-48, M42, Peccioli 1, R24, VCR4, R1O. The grapevines were established in win¬ter 1994 as cuttings grafted onto 420A, spaced at 3 x 1 m and trained to espalier with horizontal single cordon. Results obtained from observations on vegetal-pro-ductive parameters and must qual¬itative characteristics highlight a number of interesting behavioural differences between the clones exam¬ined. Briefly, quantity of grapes per grapevine was greatest in clones SS-F9-A5-48 and lowest in R1O, sugar concentration was highest in clones M42 and Peccioli 1, and polyphenol and anthocyanin levels highest in clones Peccioli 1 and SS-F9-A5-48. These results obtained from the first cycle of observations should be con¬sidered merely preliminary. Further research will be required in future years in order to obtain a sufficient number of values from adult grapevines before the outcome of research can be translated into practical applications available to wine estates.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
