Chilling requirements of apricot cultivars

Are: Mount Sha Jin Hongxing (770), Gansu purse apricot (770). Shorter are: apricot Xunyang purse (440), HL657 (480). Most of the species distribution of low demand in the 600--720 between temperature units; (3) varieties introduced from a regional perspective, Heilongjiang, Liaoning and Xinjiang in the 6.

Shaanxi, Henan, Shandong, Hebei region in 580--670 temperature between the units. 400,000,000 \7H his stare ∞ ∞ {Chang ● ● ● ●,, m lie machine Qiu cowpea \child B iv iv iv iv iv cricket Ⅲ iv iv Island threatened iv snapped ix ix to to delete iv iv iv jack m pops Bo iv iv iv iv m A ix 2 peptone Teng Wen et al: apricot varieties of low demand of 33,5, Italy 7 of 690 low-temperature units.

Shanxi Yang pockets in southern sentence minimum chilling requirements of apricot. But the HL657 Heilongjiang low chilling requirement of 480 units, the reasons for further study. Table 3 apricot varieties CRTable3Chillingrequirementsofapricotcuhivars 19 3 Northwest Plant discussed the standard for any cold weather has certainly adapt the scope of _1J. Although in some areas still not meet its export model _j, but not any place that does not meet the results of this study: Utah standard model at low temperature measured in Yang Mu-cream varieties of regional differences in the smallest, high repetition . we think. Utah model of low standards and low standards of O compared to a 7.2C, both considered high-temperature offset, but also consider the impact of temperature cycling, more close to natural conditions. Erecz (1979) high temperature in the study offset the effects of low temperature and found, 16h low-temperature, high temperature can be 8h (> 21 ℃) ,4-6C offset by the low temperature accumulated in 20-40h for the most sensitive to high temperature offset, a range of temperature and low temperature cycling is more than just help to break dormancy. temperature fluctuations in temperature (16-24C) to low temperature offset temperature is higher, offset by the greater _ \dormancy cyberspace, the greater the temperature difference between night and day in different years when there will be a great error. Despite the Utah model of the temperature on the low conversion range into smaller, in a slightly differ in their ecological areas will result in errors, but compared than under the Utah model is more consistent with the laws of nature Wang Lirong (1990), the amount of cold peach varieties that need low standard compared .0-7,[link widoczny dla zalogowanych],2 ℃ appropriate units,[link widoczny dla zalogowanych], but the results with the Utah model little difference. We are three ways measured results. Utah model,[link widoczny dla zalogowanych], compared with O a 7.2c, a difference of 38h. Therefore, Yang Mu-region model as a cream to Utah low chilling requirement varieties standard units suitable for comparison.
