Research On Propagation Biological Characteristics Of Cerasus Tianschanica Pojark

In this paper, the Cerasus tianschanica Pojark in wild-fruit forests were used as test materials whichfrom the Da Xigou valleys,Huocheng County,Xinjiang,China.The Cerasus tianschanica Pojark stems,tissue culture technology to explore from the sterile system, initial culture, proliferation culture, to thewhole process of rooting; the delicate branches and cutting,and study the different growth-regulatinghormone in the delicate branches and the deck take root in effect; Studied on removing seed shell,differentsoaking time and different hormones treatment of Cerasus tianschanica Pojark germination and radiclegrowth. Main results are as follows:1,Cerasus tianschanica Pojark first generation culture,rooted in material sterilization to70%alcohol30s+HgCl212min best; MS in media and has begun the burgeoning rate higher than B5media,which ignitedrate reached93.4%of Early generation develop the best recipe to MS+1.5mg/L6-BA+0.1mg/LIBA+30g/Lsugar+6g/L agar.2,Cerasus tianschanica Pojark subculture of plantlets best proliferation medium for MS+6-BA1.60mg/L+IBA0.10mg/L+GA30.10mg/L, proliferation coefficient as high as8.07, the average numberof bud had9.33and stem length had10.53mm while subculture of plantlets arrived35d. With the increase6-BA concentration, the stem of proliferation coefficient and the average number of bud of Cerasustianschanica Pojark. Proliferation coefficient were gradually decreased while IBA concentration wasincreasing.That higher concentration of IBA on bud proliferation has certain inhibition.Stem lengthincreases with the concentration of IBA increased gradually.3,To take root in training,take root best media recipe for1/2MS+IBA1.0mg/L+25g/L sugar+5g/L agar+1g/L activated carbon.4,Different types different concentrations of the hormone in the Cerasus tianschanica Pojark thesurvival,average root length and thickness are of a very significant impact. The concentration of100mg/Lthe IBA+100mg/LNAA soak for5min of bottom materials burn with highest survival rate,average rootlength of the long,good quality; materials bottom burn wounds after processing the different hormones anddensity for immersion cutting,whether or not the survival or quality roots are better than no burn injurieswith more obvious.5,The rate of germination of Cerasus tianschanica Pojark increased gradually as the stratificationtime.Seed coat was higher than seed shell, the highest germination rate of90.0%. In the stratification andseed soaking time phase at the same time, the seed of radicle growth was higher than that of shell, thelongest is28.59mm.Cerasus tianschanica Pojark shelled seed germination rate decreased gradually withthe increased of GA3concentration, explain GA3has certain inhibition on germination rate of the Cerasustianschanica Pojark, Inhibition with laminated seed treatments decreased gradually with the extension oftime and time24h was higher than12h on germination rate of seed soaking, and increase with the extensionof stratification time.Cerasus tianschanica Pojark to low temperature stratification above70d seed coat,different concentration of GA3and24h radicle growth was higher than seed soaked with12h; Radicle up to53.40mm.
