    This paper deals with the effects of seeaing dates on source-sink haracters of 5 cultivars in wheat, barley and triticale, and the cerlatioships among the characters and of them with clamfte factors. Dry weights of grains and vegetative organs, Ieaf area and grain volumn per spike were measured at intervals of 7 days from anthesis to maturity. The Logestic equation, quadratic polynomial model ana some other tatistical methods were used, The results indicated that most of the characters were significantly influenced by seeding dates and species or aultivars, the sensitivity of the characters to seeding dates also cpparently variea with cultivars. Among cultivars, the relationships between grain weight ana rate or duration of grain filling were probably different in importace because of the aifferences of materials, ecologica environments and the GFD's division of experiments.

    本文报导了播种期的小麦、大麦和小黑麦5个品种花后源库性状的影响。使用了逻辑斯蒂方程和二次多项式模型等统计方法,从开花到成熟定期测定籽粒和营养器官干重、叶面积的发展及持续期等性状及其与气候因子的关系。结果表明,播期和品种对多数性状有显著的影响。各性状对插期的敏感性随品种不同而异。提出了品种间粒重差异与灌浆持续期和速度的关系可能依材料、生态环境以及灌浆持续期的划分标准不同而各有主次,在不同条件下,两者相互调节,以保证最大可能地充实籽粒。

    The paper, applying trend-surface analysis (TSA) to the geographic epidemic of Chinese fir seeds in Fujian Province by giving the quadratic polynomial model, interpreting the Chinese fir sterile seed epidemic pattern, drawing the sterile seed epidemic figure and dividing it into four areas: 1. The progressively decreasing region for the sterile seed epidemic in the southwest of Fujian; 2. The progressively increasing region for the sterile seed epidemic in the southeast of Fujian; 3. The progressively decreasing region for the sterile seed epidemic in the north of Fujian; and 4. the progressively steady region for the sterile seed epidemic in the centre and the northwest of Fujian. It is suggested that the habitat of China-fir seed orchard should be selected in Jianou in the progressively steady region.

    This paper deals with the variations of source-sink characters over seeding dates, and with relations of the characters to temperature and light in wheat and barley. Dry weight of grains and vegetative organs, leaf area, grain volume and grain number/spike were measured at aninterval of 7 days from anthesis until maturity. The logestic equation, quadratic polynomial model, correlation and path analysis methods were used in this experiment. The results indicated that the variations over seedign dates and...

    This paper deals with the variations of source-sink characters over seeding dates, and with relations of the characters to temperature and light in wheat and barley. Dry weight of grains and vegetative organs, leaf area, grain volume and grain number/spike were measured at aninterval of 7 days from anthesis until maturity. The logestic equation, quadratic polynomial model, correlation and path analysis methods were used in this experiment. The results indicated that the variations over seedign dates and the responses to temperature and light were varied among the characters and species.LAD and NAR in wheat were significantly correlated with the 2 climate factors; however, only temperature was sigfiificantly associated with LAD and NAR in barley variety Zaoshu No. 3. The low temperature reduced the kernel number/spike, and high temperature reduced the volume and weight of kernel in the 2 species. But their grain weight and volume/spike increased with temperature. The variations of LAD and NAR affected the production and accumulation of dry matter to a higher extent in barley than in wheat.

    本文选取大、小麦各2个品种,采用裂区设计,在5个播期下,就大、小麦花后源库性状对日均温、日照时数的响应进行了比较研究,结果表明,源LADNAR和库容体积、重量等性状不仅对播期的敏感度因物种、性状不同而异,且对温光的响应也各异。源性状对温光变化较敏感,库性状则主要受日均温的影响,大、小麦皆然。源性状变异对大麦干物质生产和库的物质积累量的影响比小麦的大。
