Summary
These studies were made to determine the effects of graftingper se as well as the influence ofSolanum rootstocks on flowering number and percentage of fruit set, number of seeds and seeds per fruit when grafted with scions of the Russet Burbank variety.
Single and double grafts were made in the greenhouse, using Russet Burbank for both stocks and scion, and also as an interstock in the double grafts. Menominee was used as a pollen source.
Russet Burbank scions were grafted onto five Solanum understocks, two of which were of non-tuber bearing habit. These were also compared with ungrafted Russet Burbank. Two greenhouse temperatures —70–75 F and 65–70 F—were used. Shoshoni and Menominee were used as pollen sources.
Graftingper se had no effect upon flowering, fruit set, percent fruit set, number of seeds and seeds per fruit.
Solanum maglia was superior as a rootstock to all other species in increasing flower numbers, fruit set, and number of seeds. There were no differences among the other species.
Resumen
Se han realizado estos estudios con el fin de establecer los efectos del injertoper se y también la influencia de la raiz receptora deSolanum sobre el valor numérico de floración y sobre el promedio de frutescencia, sobre el monto de producción de semillas por fruto al injertársele el acodo de la variedad Russet Burbank.
Se efectuaron los injertos simples y dobles en los invernaderos, usándose Russet Burbank tanto para los acodos como para receptores y asimismo como infra-injerto con Russet Burbank de acodo y de receptor en los injertos dobles. Se usó como proveedora de polen la variedad Menominee.
Se injertaron acodos Russet Burbank en cinco raíces receptoras deSolanum, de los cuales dos no-productores de tubérculos. Igualmente se hizo una comparación con Russet Burbank no injertado. Se adoptaron dos temperaturas en los invernaderos: 70–75 F y 65–70 F. Sirvieron de proveedoras de polen las variedades Shoshoni y Menominee.
El injertoper se no presentó efectos ni sobre le floración, ni sobre el promedio de frutescencia, ni en el monto de producción de semillas, ni en la cantidad de semillas por cada fruto.
La especieSolanum maglia resultó superior como raíz receptora más que cualquier otra especie, tanto en aumento de floración, como de frutescencia y de cantidad de semillas. Entre las demás especies no se presentó diferenciación alguna.
