Hi there
This Blog-Entry serves to answer several
questions regarding in-vitro culturing techniques based on the scientific
paper: Micropropagation of a difficult-to-root weeping mulberry (Morus alba var. Shidareguwa): A popular
variety for ornamental purposes (Aroonpong, 2015).
- Whenever plants are requested for agricultural
or pharmaceutical means, its cultivation is of economic importance. To improve
the belonging work steps and even the result, detailed knowledge is necessary. The
aim of the Mulberry-Study is to receive plants with higher rooting ability
after propagation.
- To carry out a successful shoot induction,
healthy, 3-year-old plants from the field are required. After shoot multiplication
on media, the root induction comes at a different media with 1-month-old
regenerated shoots (tips and nodes).
-
The results concerning the success of different
explant types are shown in Figure 2. It’s evident that shoot tips have the
highest survival rate and are much less affected of endo- and exophytic
contamination. In addition, there were no browning to proof after 5 days of
culture in this study.
-
The duration of the different acclimation stages
is of great importance. In vitro plants require more time generally than ex
vitro, to receive a survival rate from 90 – 100 %. Crucial factors are at one
hand the room air with its specific gas composition and at the other hand the
relentlessness of direct sun light.
Another interesting method to enhance the root
ability of plants or var. Shidareguwa in special is to breed instead of in
vitro cultivation. By taking a strong rooting variety as breeding partner the
new born shoots will show aspects of both parental plants (weeping character and
strong rooting).

You summarized the required points well. There is really not much I can complain about. Maybe just one thing: I would have liked to know your interpretation of the other graphs in figure 2. Very positive I find that you put in some extra effort to present a different method for cultivating mulberry Shidarequwa - although it was not part of the blog assignment. You walked the extra mile :)
AntwortenLöschenYou did a great job with your first blog entry. Your answers are precisely and based on specialized knowledge. It seems like you really enjoyed blogging about that paper topic. From my point of view you summarized all the important points the questions asked about, in a significant scientific way. What you could improve for your next blog entry is adding your used references on the end of your conclusions.
AntwortenLöschenHey Johnny
AntwortenLöschenThank you for this well done blog entry! I really enjoyed reading it and I like the way you are “guiding” through the text by writing an introduction and some further informations in the last section. This gives the text a clear structure and awakens the interest of the reader.
As I read the same text about the micropropagation of Morus alba some days ago this short summary gives me a quick refresher about the topic, and in my opinion this is exactly what a quick summary should do. Well done!
cheers
Hi Jonathan, you extracted the main facts of the paper. I am just wondering where you take the influence of gases and sunlight during the acclimation stage from? Your final statement to solve the rooting problem by breeding is genius. Good research! Cheers Hansruedi
