10 - Organic and Biodynamic Flashcards
What is the purpose of clone selection in grapevine cultivation?
Clone selection is used to identify and propagate grapevines with desirable traits such as disease resistance, higher yields, or specific flavor profiles, ensuring that these traits are passed on consistently to new vines.
How are new grapevine clones typically produced?
New grapevine clones are produced by selecting individual vines with desired characteristics, taking cuttings, planting them, and repeating the process over several generations until the desired traits are consistently expressed.
What are some common attributes that might be selected for in grapevine clones?
Common attributes include better disease resistance, higher yield, early ripening, deep color, and small berry size.
Why might a vineyard owner prefer a multi-clone vineyard over a single-clone vineyard?
A multi-clone vineyard might be preferred for its complexity and diversity in flavor and style, as it captures a wider range of characteristics from different clones, contributing to the overall terroir and uniqueness of the wine.
What role do research institutes and universities play in the development of new grapevine clones?
Research institutes and universities conduct clonal trials, test new clones in various sites and conditions, and ensure that they meet government approval before releasing them to commercial growers.
