Sprayed "calyx agent", succulent rough "public pear" to "mother pear" ...... Recently,http://demo.web300.cn/free8/Review.asp?NewsID=627, the National pear industry technology system of industrial technology research and development center Nanjing Agricultural College officially inaugurated. Previously, Professor Nannong this team, developed a "calyx agent" formula,moncler outlet italia, so that "degeneration" after the "mother pear" taste better. And they deciphered genome, but also for fruit breeding save a third of the time.

Make "public pear" to "mother pear"
Some rough succulent pear, light taste,http://tuonela.s138.xrea.com/lightbbs/light.cgi?res=49, and some tasty pear delicate, sweet taste, which in fact is the difference between "public pear" and "pear mother" of.
Professor Zhang Shaoling is the chief scientist at the National pear industry technology system, 67 years ago, he went to Xinjiang Korla Pear growers producing for the lecture, a local pear production enterprises veterans complained,http://www.3km2.cn/home.php?mod=space&uid=67418, "Korla Pear" with "public pear" " mother pear "parts,woolrich outlet milano, no sepals" mother pear "look beautiful, good taste, high prices; and sepals" public pear "is not only irregular shape, and astringent, not sweet enough, and,http://www.mt-bbs.com/home.php?mod=spacecp&ac=blog&blogid=, because the top of the fruit sepals Some parasites also live here. In Korla Pear, "public pear" high proportion, seriously affecting the economic growers and operators.
Shao bell of this phenomenon has generated strong interest, through research, he found that this phenomenon in many excellent varieties of pears are prevalent, such as "Chi Laiyang pear" "Dangshan pear" and so on.
Why is this phenomenon? College of Horticulture, professor Nannong Wuju You also a member of the research team,http://ginga-uchuu.cocolog-nifty.com/blog/2012/05, he said, growers had cut calyx usually artificial ways to reduce "public pear" rate,http://thomassankara.net/spip.php?article1353, but this method and labor consuming and difficult to scale intensive production, and cut the top of the fruit calyx later, will leave a small scar,http://211.86.128.2/gjjl/Review.asp?NewsID=595, Fruit appearance.
To solve this problem, Professor Zhang Shaoling led the research team from the beginning of a decade ago, for "public pear" and "pear mother," the growth of all the major pear producing nearly 400 pear varieties were observed and successfully developed pear fruit calyx and simple formulations supporting technology.
"In the period grin and flowering pear calyx spray this agent, can greatly increase the rate of pear calyx." that the use of such agents can market calyx popular "Korla Pear" calyx rate increased from 47.3% to 98.2%.
Today, in addition to "Korla Pear", but this technology has been widely applied to the "Chi Laiyang pear" and "Dangshan pear" and other varieties.
Pear genome cracked password
said that unlike fruit we eat rice and rice seed generation out once a year to the 2-3 generations, breeding cycle is short, high breeding efficiency. The fruit trees there 3--5 years or even longer period children (similar to the human minor period), this time has not yet flowering fruit trees, fruit-related traits can not know, so breeding a generation of fruit trees need at least 5 years time, and breeding success requires at least 10--15 years.
May 2012, the Technical Research Centre of pear Engineering Nanjing Agricultural College academic team led by Professor Zhang Shaoling led pear complete genome fine map. Upon completion of the genetic map,doudoune moncler pas cher, and has 42,000 genes annotated pears, these genetic information for the rapid realization of gene cloning and functional studies provided sufficient data resources. & Nbsp; & nbsp; With the genetic map,louboutin soldes pas cher, what is the use? Team member Professor Wu Jun said that with the genetic map,http://store.shopping.yahoo.co.jp/ebest-dvd/0000001119673.html, we can imagine a scene like this: When the pear tree still in the juvenile period, just when the seedlings, we will know it by scanning what good genes, may in the future be What good traits, thus do not meet the requirements of trees eliminated without hard cultivation for several years, until the trees grow, flower and bear fruit before we know whether these hybrid seedlings can bear what kind of fruit. "With gene spectrum,moncler pas cher, pear breeding save a third time."
