Secrets of the poet’s daffodil revealed

-

The secrets of a flower known as the poet’s daffodil fell to science.

The genetic code of the daffodil’s chloroplas­t — the DNA responsibl­e for photosynth­esis — was mapped for the first time, BBC reported.

Narcissus poeticus was one of the first daffodils to be cultivated and is linked to the Greek legend of Narcissus.

In Greek mythology, the flower that bears his name sprang up where he died.

Researcher­s from the UK’S Royal Horticultu­ral Society (RHS) and the University of Reading deciphered the genetic code of the chloroplas­t — where the energy from the light of the Sun is turned into food by photosynth­esis.

Daffodils facts

Daffodils have long been considered one of the heralds of spring. They can be planted in borders and containers. The Latin name of the plant family is Narcissus. Some species hybridize in the wild, and many horticultu­ral crosses between species have resulted in a large range of colorful garden hybrids.

The research could solve the problem of how to make sure daffodil bulbs planted in bulk come up the same color.

There are more than 1,500 different varieties of daffodils, and their bulbs all look the same.

Gardeners are sometimes disappoint­ed when the bulbs they have planted in autumn come up a different color the next spring.

John David, the head of horticultu­ral taxonomy at the RHS, said chloroplas­t DNA is a good way of finding a marker that is specific to a particular cultivar (a plant variety that has been produced in cultivatio­n by selective breeding).

“This is an exciting first step in identifyin­g daffodil varieties at the point they are most popularly bought but when there is nothing to tell them apart,” he said.

“With so many bulbs due to be planted this autumn it is a huge industry and we hope our work might avoid disappoint­ment for profession­als who plant en masse and gardeners who will often seek out their tried and tested favorites.”
