Patents for the Physiological Quality in Seeds of Peach Rootstock Classified by Weight and Stored for Different Periods.

Background: Among stone fruit, the peach (Prunus persica (L) Batsch) is one of the most widely grown species in Brazil, in both area cultivated and in production.

Objective: The aim of this study was to evaluate the physiological quality of heavy and light seeds of four cultivars of Prunus persica for two storage periods, from tests of electrical conductivity, germination, and an analysis of initial plantlets growth.

Methods: The Electrical Conductivity test (EC) was conducted in a Completely Randomised Design (CRD), in a 4 x 2 x 5 factorial scheme with five replications.
