[Study on Variety Test of Salvia miltiorrhiza New Variety “Zhongdan 1”]
Objective:
The new varieties of Salvia miltiorrhiza were bred by the variety comparison test.
Methods:
Taking these varieties of CDS1,CDS2,CDS3,CDS4,CDS5 as the test varieties, which bred by system seletion from abundant germplasm resources,the conventional variety as the control, the test were arranged in Ximeishan, Linjiagou, Shiya, Hexing Village of Zhongjiang county in 2010 and 2011. And the new varieties from the growth cycle,line of characters,yield, quality and other aspects of Salvia miltiorrhiza were evaluated.
Results:
CDS2 had the highest yield which was significantly higher than the control group. The growth period were 250 ~ 270 days,the seed germination were early,and the plants were taller. And the medicine merchandise traits were better, the salvianolic acid and the tanshinone were significantly higher. CDS2 was named as the "Zhongdan 1"by crop variety Committee of Sichuan province in2012,which identified by technology field in 2011.
Conclusion:
"Zhongdan 1"is a new variety through the certification authority validation,which has a great popularization value in the production.

02:15SN1 Reaction: Stereochemistry
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...

However, Sir Christopher Ingold and Edward D. Hughes, who studied the kinetics of various nucleophilic substitution reactions, noticed that a tertiary alkyl halide does undergo a nucleophilic substitution reaction in the presence of a weak nucleophile. While studying the substitution...
02:25SN1 Reaction: Mechanism
Firstly, the haloalkane ionizes to generate a carbocation intermediate and a halide ion. This heterolytic cleavage is highly endothermic with large activation energy. The ionization of the substrate, facilitated by a...
02:42Acidity of 1-Alkynes
The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.
