Does roses have pollen
Roses have pollen, but usually people are so amazed by the beauty of the flowers that they ignore the fragrance and the existence of the stamens.
Roses are not only nutritious but also have medicinal effects. When I was a child, my mother fried eggs with roses for me. Later, I also drank tea made with roses, red dates and wolfberry for a while. After drinking it, my face became much rosier and The hair loss situation has improved a lot. Yunnan’s rose cake should be considered a household product, so of course it can be eaten with food. If you want to try eating roses, it is recommended that you buy edible roses and try not to buy roses that are used as cut flowers, because the pesticide residues in ornamental flowers are a bit heavy.
I just watched a plant documentary about flowers “The Journey of Flowers” a few days ago. It only has 2 episodes and talks about the evolution and history of four types of flowers: tulips, iris, lotus, and rose. What I want to share today is roses, the relationship between rose evolution and humans.
Most of the roses we see in the market are modern roses, which are plants of the genus Rosa in the Rosaceae family. The story begins with the dog rose. Its appearance is very simple, with a single petal, light pink, and 5 petals. It blooms in summer and lasts for several weeks.
It has a simple beauty and back then it was one of the bees’ favorite flowers. It has no nectar, but can produce large amounts of pollen, which brings food to pollinating animals.
By chance, a single-petaled rose mutated into a double-petaled rose. This was originally an undesirable mutation, but due to human intervention, this mutation was artificially strengthened. This gave rise to the roses and roses we love later. The beauty of the modern rose.
The rose’s transformation from single petals to double petals was achieved at the expense of the stamens. What does the sacrifice of stamens mean to the rose? It means that it loses the chance to compete in the reproduction of nature. The stamens mutate into petals, and the amount of pollen they can produce is greatly reduced. Even if bees visit, they cannot take away much pollen. Relying on the power of nature, its reproduction becomes more and more difficult.
We can now enjoy various rose colors because humans have mastered the technology of asexual reproduction of roses and interfered with the process of plant pollination.
A bee is attracted by the bright flowers of a rose and tries to get between the complicated petals to find the presence of pollen. It is doomed to return in vain because the real petals of this huge flower only have 5 of the outermost rings. There are hundreds of petals, and the other hundreds of petals are all mutations of stamens. The stamens of that flower are pitifully few. It no longer needs bees for its reproduction, but it needs humans.
Humans use cuttings, layering, and tissue culture to obtain more of the same variety, and artificial pollination and hybridization are used to obtain the desired flower color, flower shape, and floral fragrance. After years of exploration, excellent breeding experts have long mastered the rules of hybridization. Although the offspring obtained from crossbreeding may not be the results originally planned, such unexpected traits cannot be cared for by humans. Without humans, Take care of it, and its ending will only disappear.
According to the classification standards of the American Rose Association in 1966, all rose varieties that appeared in 1867 are called “ancient roses”, and rose varieties that appeared after 1867 are called “modern roses.” There are many varieties of roses, including varieties specially used for cut flowers, climbing roses, varieties for extracting essence, edible varieties, mini varieties, etc. According to different market demands, horticultural breeders are constantly selecting and breeding varieties that are more in line with human needs. Varieties, and what roses have to do is no longer trying to avoid natural enemies, attracting pollinators, germinating and producing seeds, but mutating and mutating.
In the cultivation history of more than two thousand years, humans have accelerated the evolution of roses, and at the same time made the self-reproduction ability of roses extremely fragile. Your favorite roses can no longer be separated from humans.
