In order to make technical regulations for seed production and to provide evidence for improving yield and quality of licorice seeds,this study did research on seed- setting characteristics and seed yield factors of Glycyrrhiza uralensis. Seed- setting characteristics and seed yield per plant were observed in Glycyrrhiza uralensis. productive phase,seed yield factors were measured and analysed. The Results showed that reproductive branches per plant,pod number per branch,seed number per pod,weight per seed,plant height,inflorescence position and pod width were significantly correlated with seed yield. Reproductive branches per plant,pod number per branch,weight per seed,inflorescence position and pod width were highly significantly correlated with seed yield. Maturity of pod was highly significantly correlated with 1000- seed weight. The multiple linear regression model of seed yield per plant was Y = 0. 5177X1 + 0. 5851X2 + 0. 2888X3 + 0. 3872X4. Reproductive branches per plant,pod number per branch,seed number per pod,weight per seed were the basic component factors for the seed production of Glycyrrhiza uralensis,pod number per branch and reproductive branches per plant were the main component factors,they had the biggest direct effect on seed yield. Plant height,inflorescence position,pod width,and pod maturity were the important factors of Glycyrrhiza uralensis seed yield,the plant which was taller,had inflorescence in axillary or had wider pod,will be more productive. Pod maturity had significant effect on the weight of 1000- seed. 1000- seed weight would reach its maximum when the pods turned brown and were fully ripe.
Glutaredoxins( GRXs) are oxidoreductases that mediate reduction of disulphide bonds of cysteine residues of target proteins. It has been predicted and divided into three major classes in plants,namely CPYC- type,CGFS- type,and CC- type. Among these,the CC- type has so far been identified only in land plants. CC- type GRXs were shown to exert crucial functions both in floral development and in abiotic and biotic stresses responses. In this study,we constructed two RNA interference( RNAi) vectors for CC- type GRX- Os GRX6 in rice,targeted its 5'and 3'end sequences respectively. And it will be helpful for further elucidation of the biological functions for Os GRX6 in rice.

Sunflower White Mold caused by Sclerotinia sclerotiorum is a kind of disease distributed world widely. Sclerotia formed by hyphae plays a vital role in the disease cycle. Using sunflower sclerotia as material,we studied the effects of different culture conditions on the formation of sclerotia. Our data suggested that medium with different carbon sources has different effects on the formation of sclerotia. Medium contained lactose,soluble starch,maltose,rhamnose or mannose facilitate the formation of sclrotia; the medium with mannose produced more abundant sclerotia compared with medium contained the other carbon sources. The optimum p H value for the formation of sclerotia is between 3 ~ 5; and the formation of sclerotia could low down the p H value in the cultured medium. 20℃ ~ 25℃ is the suitable cultured temperature for the formation of sclerotia. Different cultured mediums have different effects on the formation of sclerotia. Oat medium facilitated the formation of big volume sclerotia,however,the czapeks medium could produced small and abundant sclerotia.

In this paper,a detection method of contours of wheels for high real- time is proposed. Since the classic codebook algorithm is difficult to deal with the situation such as global sudden light changes,a improved codebook algorithm is presented. First of all,the moving vehicle is extracted in the video recording the side of vehicle by the improved codebook algorithm. And then the contours of the object are extracted in the binarization image processed by the optimal threshold algorithm. Then all the circularity of the contours are calculated by the circularity formula to locate the circular contours. At last the circular contours located by calculating the circularity are verified by Hough transform circle detection method. Experimental results show that this method can locate the wheels of vehicle with high real- time and strong robustness.
