Excerpt from Apricot Growing in California The principal rootstocks used for apricots are apricot, peach, and myrobalan. The apricot and peach are more generally used than the myrobalan. The apricot cannot be relied upon to make a strong union with the myrobalan, for, although the trees often grow well for a number of years, they are apt to break at the graft union under stress of heavy loads or strong winds. The apricot root is resistant to the attacks of nematodes and the Pacific peach tree borers, and for this reason is valuable in districts where these pests are known to exist. All three principal rootstocks used for apricots are more or less susceptible to crown gall. The myrobalan is thought by some growers to be more resistant to oak fungus than either the apricot or peach, and is therefore used to some extent as a rootstock for the apricot. A questionnaire submitted to the nurserymen of California by the Division of Pomology showed that the percentage of apricot trees propagated on apricot stock in the years 1923 to 1928 inclusive varied from 30 per cent to 56 per cent. The percentage on peach stock varied to approximately the same extent. The percentage of apricots on apricot stock was greater than on peach stock four years out of the six for which records were obtained. The proportion of apricots on myrobalan decreased from per cent in 1923 to about 12 per cent in 1928. A few apricots. On Davidiana stock were also propagated during this period. In 1929 approximately 46 per cent of the apricot trees propagated were on apricot root, 16 per cent on myrobalan, and 38 per cent on peach. The almond is not used as a. Rootstock for apricots.
