Just imagine, a beautiful rose looks attractive from a distance, but when you get closer to smell it, there is no scent to be picked. At another time, you find a similar rose and as you smell it, you receive the sweet aroma. You cannot just ignore such differences because they remind you that there should be facts to back up such observations. That is why you may sit back and wonder how two roses with the same visible physical features would have such differences. What was eventually found gives more basis for taking extra caution in the future. In certain cases, the problem has been blamed on differences in our sense of smell. But this does not explain why such differences exist within the same family of flowers.
Scented roses on the market today are not the same as what existed in the past. All roses have gone through many changes over a long period, and it is not easy to trace back to what point the qualities were tempered with. Scholars observe that factors related to the environment and other issues have a role to play in these changes. It is mostly well understood when dealing with roses because they have attracted the attention of many beauty products. Without realizing it, gardeners cross-breed a variety of roses and eventually change their former qualities. In some cases, a gardener just grows two attractive rose varieties next to each other without knowing the long-term effects.
The findings reveal that farmers grew species of different qualities without knowing what was going on. This caused them to sacrifice the sweet smell for their attractive appearance. Therefore, you cannot easily find a rose flower having both characteristics of a sweet smell and an attractive appearance. However, there are other gardeners who never succumbed to such a problem. As much as possible, they tried to separate the flower species accordingly so that there was no contamination. These preserved the true qualities of the scented roses.
Another reason that has separated smelling flowers from those that do not is the deliberate attempt by expert gardeners to experiment with rose flower breeds. This group carries out well-organized breeding with a view to bringing out new types of roses which are appealing for commercial purposes. As their experimentation continues, it has become all too easy to lose the appealing smell with the compensation coming from an intriguing blend of new colors. For this group of farmers, they end up with beautiful roses that do not smell. At the end of the day, such results are just in line with their wishes.
Modern research has come to find that there are more than 20 species of vegetation related to the rose flower. Some of them include species that do not carry any smell. This identification process has led them to validate their findings, and conclude that some roses should not have the desired smell. Such logical explanations have given good reasons why groups of such plants may have beautiful or unique petals but with a compromised smell. The same method was used on attempting to explain why other roses are scented. It was established that such plants were related to other varieties with sweet smells.
Other studies by scientists have now revealed that the scented rose has an enzyme which is normally active in it. In roses with a good scent, the enzyme is not suppressed. It works together with other pigments to produce the lovely odor. In petals with no scent, this enzyme is either inactive or dormant. As such, it does not work to produce the result of combining to produce the good smell every rose is known for.
Looking at these pieces of evidence, as you have seen, the main reason why some roses end up smelling while others do not is dependent on a number of factors. This family of beautiful plants can easily be related to special types of plants exhibiting the qualities they have. As farmers have worked over time, they have contributed to the coming of new varieties leading to a compromise between scented roses and scent-free ones. These flowers primarily produce the scent to attract the bees which carry out the pollination process. Wild flowers and even wild roses carry the scents for the same reason. Failure to bring out scents does not affect pollination drastically.
