本试验观察了黑穗醋栗两个品种(厚皮黑穗醋栗和薄皮黑穗醋栗)。在哈尔滨地区,这两个品种均于十月中旬进入休眠,当时平均气温为5.9℃左右。薄皮黑穗醋栗进入休眠和结束休眠均较厚皮黑穗醋栗早。薄皮黑穗醋栗在11月28日开她解除休眠,而厚皮黑穗醋栗在12月18日开始解除休眠。薄皮黑穗醋栗半数以上的芽子在1月中旬以后结束体眠,而厚皮黑穗醋栗在2月下旬。自然休眠解束后,由于外界条件不适芽子仍处于休眠,这种现象称作被迫休眠,一但条件适宜时,芽即可膨大生长。
In this experiment, two varieties of black currant (black-skinned black currant and black-skinned black currant) were observed. In Harbin, both varieties came to sleep in mid-October when the average temperature was about 5.9 ℃. Thin-skinned black currants go to sleep and end to sleep thicker-skinned black currant early. The thin-skinned black currant opened her to sleep on November 28, while the thick-skinned black currant began to release her sleep on December 18. More than half of the thin-skinned black currant buds end after the mid-January, while thick-skinned black currant leaves late February. After the natural dormancy solution, because the external conditions are not suitable buds are still dormant, this phenomenon is called forced dormancy, but the conditions are right, the bud can be expanded.
