The contents of C,H,O and methoxyl groups of MWL the purified milled wood lignin(MWL) extracted from walnut shell(Juglans sigillata) were determined and the basic chemical groups of MWL were characterized by 1H-NMR.
In this experiment,freshly harvested Asiatic hybrid lilies were treated with fundamental preservative ingredients(20 g·L-1Sucrose,250 mg·L-18-HQ,1 g·L-1CaCl2)plus 35 mg·L-1 salicylic acid,and then the preservation effects were investigated.
3 In differentiatia and subculture stage, Silvervein Creeper easy brown, and attachs PVP 300 mg/L alleviate the brownization degree. The fundamental culture medium of more fit growth of Silvervein Creeper is 1/2MS and GS, that attachs BA 0.5 mg/L, and NAA 0.06 mg/L;
(or Italian ryegrass). Line 4,6 and 8 are salt resistant lines selected from the radiotion-indueed mutants of Orygon. The somatic chromo- some nember of Orygon,Line 4,6 and 8 are 2n=4x=28.These karyotypes are 2n=4x=26m +2sm(2SAT)and belong to fundamental symmetry.
The picture of BR signalling is emerging in recent years. The main components of BR signal transduction include the cell-suface receptor kinase BRI1, the glycogen synthase kinase-3-like kinase BIN2, nuclear proteins BZR1 and BZR2/BES1. A recent study defines BZR1 as a central regulator for coordinating BR signalling, BR biosynthesis, and growth responses.
The modified isolation buffer was: 100mmol/L Tris-HCl (pH 8.0), 20 mmoI/L EDTA, 1.4mol/L NaCl, 2% CTAB, 3% PVP-40, 1% β-Mercaptoethanal and 20 mmol/L Na_2S_2O_5.2.After systematically study on the main factors involved,an AFLP silver-staining analysis system suitable for chestnut genomic DNA was established.
The main results were as follows:()The changes of the generation rate of O_2~-, content of H_2O_2、 MDA, GSH, AsA and the activities of SOD、 POD, CAT、 GR, APX in leaves of virus-free jujube Junzao trees were similiar with that in leaves of common jujube Juzao trees. There were the same chages in water-stress.
Main mineral elements contents of soil and leaves of early bearing walnut were determined from 2004 to 2005. The results showed that the annual changes rule of the same mineral element was similar in different years, but there had a little different changes.
On the contrary, the 15N absorption by large leaves and basic leaves on spring shoots only occupied 50% of that of large leaves on autumn shoots, and 15N moved primarily to the lower parts and in the main,didn't move to the upper parts.
One is that quality and efficiency are basis and premise of enterprise existence and development. The other is that technique and strict management are key to improving quality and efficiency. Moreover, some problems of flower factory production were analyzed and discussed.
on th e basis of MG 5 medium,the lycopene contents under 100 0-120 0g·L -1 of sucrose concentration among 7 treatments and 30 0-50 0mmol· L -1 of PO 3- 4 concentration among 13 treatments were very significa ntly higher than those of the other corresponding treatments,and better for lyco pene synthesis of carrot cells.
On this basis, To solve the problem about the origin of the haploid regenerated plant ,the embryogenesis process was revealed in the embryology level and confirmed the fact that the haploid regenerated plant came from the egg apparatus and that some haploid regenerated plants became diploid plants autogenously in the development process.
(Taiwanqingzao)The combination of different kinds and concentration of growth regulators were studiedaccording to callus production rate of explants, callus weight of explants in initial culturemedium and callus progression in subculture medium on basis of MS medium in Zizyhpus mauritiana Lam. (Taiwanqingzao). The proper initial medium: MS+2,4-D (0.5mg/L) +KT (0.1mg/L) (Young fruits);
Applications to constructing a basis inZ(g) for classical g are also sketched.
A basis is calledmonomial if each of its elements is the result of applying to a (fixed) highest weight vector a monomial in the Chevalley basis elementsYα, α a simple root, in the opposite Borel subalgebra.
On the basis of these solutions, two types of elliptic quantum groups have been introduced (Foda et al.
We describe a basis forY, show that it is a polynomial algebra and describe its rank, which we compute explicitly in a number of cases.
Our basic tool is Lusztig's canonical basis and the string parametrization of this basis.
