Demystify Science | Toward penpinized lemons

Every week, our journalist answers readers’ scientific questions.

Because without seeds, the market for glitches is not big enough, answer a few researchers. However, the types of pissed-free lemons are still in recent years, especially beautiful, California company.

“Generally, when you take a lemon at home,” Albert WU, a biologist, a biologist in the Genomic Institute of American energy department.

According to a specialist and author of a genealogy lemon tree published in the magazine in 2018 NatureSeeds are inconvenient for seeds for “citron press or water extractor”.

Therefore, it is beautiful in the restaurant market and the food industry, which does not meet the interviews, the district Kahn, said Tracy Kahn, who manages the collection of 1050 lemon variety at the University of California.

The Biologist Frederick Gmitter believes that they will end at Florida University, which produces simply different seedless lemons. “When you pick up a quarter of a lemon with a glass of water or lemon slices in your cocktail, the seeds are equestrian.”

According to Gmitter, the term “without seed” falls into the term because seedless lemons do not “98% or 99% of the time.”

“I know that its lemons have no entirety of its lemons, but I know the guy who produces its range,” Mr Gmitter said. What he did, there are very few seeds, but there is anyway. “

Is it the same for other citrus fruit? “Yes, there are only a number of mandarins from Japan, because it can really be said without seeds, because it is very durable to pollution of other species,” Mr. Gmitter explains.

Lemon, bitter orange and cedrat, often a lemon used as a decoration plant, is a kind of orange and cedrate passage. The bitter orange is the passage of Pomelo and Mandarine itself. “This means that the lemon passes through three species,” he said.

In turn, Meyer’s lemon expresses a bitter orange, Mr. Wu, which is not available today.

And file in all this? This comes from the crossing of the decorating citrate, Mr. Wu.

Less sharing

“Givaudan” collection is managed by m^my Kahn would be the most important in the world. “There are lemon collections that have more trees, but there is no one with so many different types.”

The collection, which has been built 100 years ago, has been growing slower for several years. “Countries are jealous of plants, so there is less share,”^my Kahn.

New types of lemons are created from a technique that creates traditional or radiation crosses, mutants faster. Genetic engineering, but is planned to fight against a bacterial disease called “Green Citrus” or “Huanglongbing” (HLB), Mr. Gmitter.

HLB has reduced the production of citrus in Florida for 10 years.

According to Mr. WU, Australian Wild Citrus can help fight against the HLB.
