Question

Which one of the following belongs to stolon?
A) Fragaria
B) Doob grass
C) Pineapple
D) Banana

Answer 1

Hint: It is the genus of the flower usually known as the strawberry for their edible fruit part mainly in the family Rosaceae. Stolon is an elongated, vegetative part which the main function is the development of plants.

Complete answer:
Fragaria is a genus of flowering plants widely known as strawberries for their edible fruits in the rose family, Rosaceae. There are even more than 20 species and several hybrids and cultivars that have been identified. Garden strawberry cultivars, a hybrid known as Fragaria × ananassa, are the most common strawberries grown commercially. The taste of strawberries varies from variety to variety, ranging from rather sweet to rather bitter. Strawberries are an important commercial fruit crop, widely cultivated in all temperate regions. In the plant-to-plant relationship, bare-rooted Camarosa ramets, joined in pairs by their own stolon’s (usually the second and third ram in a runner chain) were transplanted into two pots to describe strawberry stolon action.

Hence, the correct answer is an option (A) 'Fragaria'.

Additional information:
Stolon is an elongated, vegetative, axillary, two-node shoot that sustains the ramet (rooted rosette) until it is fully independent of its own roots. There is still controversy about the mutual ability of the ramets, in a single runner chain, to retain the growth and share locally rich resources or to withstand local pressure.
This capability can play an important role in improving the development of nursery plants and in improving the understanding of natural clonal multiplication. In the plant-to-plant relationship, bare-rooted Camarosa ramets, joined in pairs by their own stolon’s (usually the second and third ram in a runner chain) were transplanted into two pots to describe strawberry stolon action.
The pairs of ramets were handled with decortication (peeling a 2 mm bark ring from the stolon), elimination of the root system or application of glyphosate to either of the two ramets in a factorial experiment. In the method analyzed, the older ramet was referred to as the mother as well as the other ramet as a daughter.
The two ramets are very close in age and seem to be behaving with the mother's very minimal hierarchical prevalence. When the root system of one ramet was removed, there was a very small decrease in leaf number and chlorophyll content, either in the mother ramet or even in the daughter.
In either community of plants, the decortication did not decrease water incorporation but reduced assimilate allocation to the daughter ramet when the mother ramet had a serious root cut (not vice versa). The glyphosate activity resulted in the localization of the sprayed ramet, which reduced the chlorophyll content within 2 days and expired after 4 days.

Note:
Fragaria besides low content of fats and calories, it is a great source of anthocyanins, flavonols, ellagitannins, ellagic, phenolic acids and terpenoids. In addition, anti-ageing, neurological disease combating and anti-cancer properties are included.
