黑麦碱

The chromosomal constitution of 200 advanced lines from 1R monosomic addition lines between the wheat cultivar Mianyang11 (MY11) and different rye lines R3, R12, and Baili-rye was studied by the improved C-banding and A-PAGE method. The result showed that 45 lines were identified as 1RS/1BL translocation lines congruously by the two methods. But a line (843-1-1), originated from an 1R addition line of wheat cultivar MY11 and rye line R12, was identified as 1RS/1BL translocation line by C-banding and genomic in situ hybridization,but the secalin block from chromosome arm 1RS of rye was absent in the A-PAGE pattern of its seed proteins.

结果发现，在鉴定的200个株系中，有45个株系经C-带和A-PAGE检测均一致地发现它们含有一对1RS /1BL易位染色体，而一个株系843-1-1，C-带鉴定、原位杂交结果均证明它含有一对1RS/1BL易位染色体，但A-PAGE醇溶蛋白图谱却不具有黑麦1RS染色体臂的黑麦碱特征带，而表达出既不同于黑麦碱又不同于亲本绵阳11的醇溶蛋白带型。

Be in 1920, during 1930, the researcher strive of Russia and Sweden obtains triticale again can the fructification of breed, but did not succeed. Discovered meadow saffron is alkaline 1937, breed in the success of triticale in the center became decisive factor.

在1920—1930年期间，俄国和瑞典的研究人员力图再一次取得小黑麦能够繁育的果实，但是没有成功。1937年发现了秋水仙碱，在小黑麦的成功培育当中成了要害性的因素。

The results indicated that an improved 1BL/1RS translocation has Glu-B3 and Yr9 without secalin,and has higher SDS-sedmentation value than common 1BL/1RS translocation.

结果表明，在87份材料中鉴定出了一种新的改良1BL/1RS易位系，该类易位系的特征是：含有来自1RS的抗条锈病基因Yr9、不含黑麦碱、具有Glu-B3基因、比一般1BL/1RS易位系具有明显偏高的SDS-沉降值。

Results showed that cultivation of forage crops, especially ryegrass and rye, in winter improved soil properties over cultivation of grain crops by lower soil pH and increasing contents of organic matter and available nutrients, which contributd to growth and possibly yield of the crop to follow.

结果表明：冬季种植牧草与种植粮食作物比较降低了土壤pH值、增加了土壤有机质和速效养分，特别是冬季种植多花黑麦草和黑麦明显增加了土壤有机质、碱解N、速效K和速效P含量，促进后作生长，为后季作物增产提供可能性。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
