| Sumario: | The exact knowledge of the species and / or variety of a rootstock determines the quality of the plant to be obtained and avoids using cups on incompatible rootstocks. Among the objectives of the Law on Seeds and Phytogenetic Creations No. 20,247 is to ensure the quality and identity of the seed that the producer acquires. The objective of this work is to be able to know the species and / or variety of a rootstock through the morphological characteristics of the seed. Using seeds from the rootstocks with which we work in Argentina, the quantitative morphological characteristics (length, width, thickness, length of the tip) were measured and the qualitative characteristics (color of the epidermis, color of the integuments) were observed. The parameters taken allowed to show significant differences between the different species and / or cultivars. With these differences, a dichotomous key was developed that allows differentiating the 21 rootstocks used in Argentina. |
