鸭跖草的开发与利用

鸭跖草科植物鸭跖草(Commeline communis L.)在我省山区、半山区广为分布,历来绝少药用,十分可惜。鸭跖草可清热解毒,利水消肿。已载入《中国药典》。该药具有抗菌、抗炎、镇痛、止咳等多方面药理作用。开发应用,利国利民。鸭跖草的嫩苗和嫩茎叶,尚可做野蔬食用。

Influential Factors of Restorer of New Cytoplasmic Male Sterile(NER) on Anther Culture

Some influential factors of anther culture were studied preliminarily by conducting anther culture of the restorers of new cytoplasmic male sterile （NER）. Several results were obtain from this experiment and they were listed as follow：① MS cultrure medium with such hormones as 2,4-D 2 mg/L,6-BA 0.5 mg/L, NAA 0.5 mg/L was the best suitable for callus induction of NER. ②The difference of induction rate was significantly different between different plant age groups. From the 110th day to 141th day,the induction rate was increased with the increase of age and the difference of induction rate reached 0.01 significant difference level. The induction rate reached the highest value in the 141th day then it declined gradually. ③The combined use of 2, 4-D and 6-BA with proper increase of 2,4-D was good for inducing callus. ④The green plantlet induction rate of NER was increased when the concentration of 6-BA increased from 2 mg/L to 4 mg/L. Adding ZT from 0.5 mg/L to 2 mg/L. 6-BA would led 2.47% increase of green plantlet olantlet induction rate.

Production of Partial New-typed Brassica Napus by Introgression of Genomic Components from B. rapa and B. carinata

A breeding strategy for widening the germplasm of Brassica napus was proposed by introgression of the A^r subgenome of B. rapa （A^rA^r） and C^c of B. carinata （B^cB^cC^cC^c） into natural B. napus （AnAncncn）. The progenies with 38 chromosomes that were derived from the self-pollinated seeds of pentaploid hybrids （A^rA^nB^cC^cC^n） were used for further research. Some of the partial new-typed B. napus showed normal meiotic behavior, high portion of germinated pollen and normal embryological development. This indicates that the selected new-typed B. napus had a balanced genetic base. Molecular analysis showed that about 50% of the genome in the new-typed B. napus was replaced by A^r and C^c subgenome from B. rapa and B. carinata. Considering the genetic diversity among different lines of new-typed B. napus, it was deduced that the introgression of the genomic components from B, rapa and B. carinata could widen the genetic diversity of rapeseed.

花椰菜黑腐病的发生与防治

近两年,花椰菜黑腐病发生日益严重。农民误认为是真菌性病害,往往用真菌性药剂防治,结果根本防治不住,造成减产。其实花菜黑腐病是细菌性病害。在适合条件下,只要侵染,维管束系统就发病,治也治不住,造成减产。因此防治这种病要＂预防为主,防治为辅＂。呼吁广大农户一定要认清＂细菌性黑腐病＂,正确防治。

Yield Stability of Direct-sowing and Early-maturing Excellent Brassica napus (Attar No.8)

[Objective] The aim was to analyze yield stability of attar No.8, which is direct sowing and early-maturing. [Method] Analysis was made on yielding ability, stability and adaptability of attar No.8 in Yunnan Province during 2006-2009 with DPS software and stability assessment was conducted on yield and major economic characters of the variety in different periods and experimental plots. [Result] Average yield of attar No.8 during three years in 24 plots achieved 3 379.17 kg/hm2; it grew tightly and is featured with early matureness. In addition, grain density, pod number and annul production differed little in different years and the variety in eight ecological conditions all showed high production potential, yielding ability and stability, which proved that attar No.8 is suitable to be grown in Yunnan and southern early-maturing areas in China. [Conclusion] The research provided references for selection and breeding of rapeseeds＇ variety which enjoys high and stable yield.
