Some insights into the vernalization of roses
Abstract: This article discusses the knowledge of roses, some insights into the vernalization of roses, let's learn about them together.
Questions about the vernalization of roses are of more concern to rose enthusiasts in southern regions, as they find that some roses only grow in size but do not bloom, so they are very puzzled whether it is the problem of rose vernalization. In response to this issue, I have reviewed a lot of feedback from rose enthusiasts.
The concept of vernalization: Some flowers require low temperature conditions to promote the formation of flower buds and the development of flower organs, this process is called the vernalization stage, and the low temperature stimulation and treatment process that enables flowers to pass through the vernalization stage is called vernalization.
Some statements about the vernalization of roses: Currently, there is no scientific evidence to say that roses need vernalization to bloom, and according to the experience of most rose enthusiasts, most rose varieties do not have high requirements for vernalization. So the question comes, why do roses have a low blooming rate in southern regions (such as Hainan), and some varieties even do not bloom?
This is mainly because the temperature difference in Hainan is small, which is not particularly favorable for the characteristics of rose varieties, and because it grows all year round, unlike the north where it can store nutrients in winter, so compared to planting roses in the north, the blooming amount is a bit poorer.
In conclusion, it is recommended that rose enthusiasts in the Hainan region should choose varieties that bloom in multiple seasons when selecting rose varieties, and avoid single-season blooming rose varieties as much as possible. Moreover, when choosing varieties, it is a good idea to first look at the feedback from other enthusiasts. Although it cannot be said that there is an absolute relationship between rose blooming and vernalization, there are indeed some varieties that do not bloom well in the Hainan region.
The above is the complete introduction to the insights on the vernalization of roses, for everyone to learn and understand!
