For several years, various research institutions of pomology and agricultural colleges have been giving a great deal of attention to the study of grape varieties with the aim to add new and better varieties either as table grapes or for the wineries. With the progress of the work, it becomes increasingly clear that in order to coordinate the efforts of the various in-stitutions, it is necessary to smooth out certain differences in the method of observation and in the use of descriptive terms....

在葡萄品种研究工作中,各研究单位的观察记载项目、标准和方法,存在着或多或少的差异,同时也有一些疑难问题,需要讨论解决。本文扼要介绍今年7月由河北省农业科学院果树研究所和河北省果树学会联合召开的“葡萄品种研究学术座谈会”对这些问题讨论的经过,着重提出了一些意见不尽一致,有待进一步研究的问题,并将会议所制定的“葡萄品种观察记载的项目、标准和方法(草案)”发表,供各地葡萄研究工作者的参考。

In april, 1964, a meeting was summoned by the Peking Botanic Gardens, Research, In-stitute of Botany, Chinese academy of sciences, to discuss the various problems concerning the research project on improvement of grape varieties. Among other topics, the procedure and technique of grape breeding received a great deal of attention from those who attended that meeting. This paper attempts to present the results of discussion on this topic.

今年4月,中国科学院植物研究所北京植物园在北京召开了“葡萄品种选育的研究”专题第一次会议,讨论并制定了“葡萄杂交育种程序(草案)”。根据这个草案,从杂交到决选出预备新品种,在一般情况下,需时15至17年。会上对何时开始繁殖优良单株,对复选出来的优良单株和进行比较试验时观察测定的项目等问题,展开了热烈的争论,这些问题,关系到育种年代的长短,杂种苗各种经济性状的稳定程度,以及观察测定所需工作量的多少,是值得重视和继续探讨的问题。本文根据讨论结果,加以整理,供各地葡萄育种工作者的参考,并请提出修改补充的意见。

The root segments of three grape varieties were frozen at certain temperatures below 0℃. As comparative indices of their frost damage, the percentage of leakage of electrolytes and the percentage of reduction of TTC for the treated tissues were measured by means of electric conductivity method and TTC method respectively. The treated root segments were then cultivated in warm conditions for 7-10 days to see whether they were alive or not in order to deduce the threshold index value and critical temperature...

The root segments of three grape varieties were frozen at certain temperatures below 0℃. As comparative indices of their frost damage, the percentage of leakage of electrolytes and the percentage of reduction of TTC for the treated tissues were measured by means of electric conductivity method and TTC method respectively. The treated root segments were then cultivated in warm conditions for 7-10 days to see whether they were alive or not in order to deduce the threshold index value and critical temperature causing inreversible damage, and used for frost tolerance of the root tissues. The results showed that among the three grape varieties, the Amur grape has the strongest frost tolerance in root, Beta comes second and Jufong the poorest. In the former two varieties, the frost tolerance increased gradually as the winter became severer, and expressed the intrinsic inherent genetics. But the latter showed neither significant change nor any rules. When the growing season came, their frost tolerance decreased significantly all the same. In this paper the variation of the two indices and the reason why the peak of TTC reduction oecured in the range of sub-damage temperature were discussed. The results showed that the electric conductivity method seemes to be more practical than TTC method, and the latter has unique sensitivity in research into the mechanism of frost tolerance.

用不同程度的零下低温对三种葡萄的根段进行冰冻处理,用电导法和TTC还原法检测处理组织的电解质渗出率和TTC还原率,作为冰冻损伤程度的定量比较指标。将各组处理的根段保温培养7~10天,从其外观变化鉴别死活,据以推断冰冻对根组织不可逆致伤的临界指标值和临界温度,用来比较鉴定其耐寒力强弱。结果表明:三种葡萄根的耐寒力以山葡萄最强,贝达次之,巨峰最低。且前二者的耐寒力随着冬季进程而增强,逐渐显示出其固有的耐寒遗传特性,而巨峰的变化不明显和没有规律。至春季生长期,其耐寒性都显著降低。本文还根据研究结果讨论了两种指标之间的关系和变化规律。并着重分析了次致伤低温区出现TTC还原高峰的问题。两种测定方法在研究葡萄根的耐寒力方面,表现出电导法的实用性优于TTC还原法,但TTC法在探索耐寒机理方面有其独到的灵敏性。
