Q249

Sucidal germination take place In

A.
Dodder
B.
Striga
Answer
C.
Loranthus
D.
Dendrophthoe falcata

Answer: Option B

Solution

Answer: Option B
Solution:
Suicidal germination takes place In Striga.
Striga seedbank depletion can be achieved by suicidal germination, a strategy where the Striga seeds are stimulated to germinate in absence of a true-host plant.
In suicidal germination, parasitic weeds are germinated without a suitable host. In this way, before crop cultivation, weeds are died off.
Infestation by the parasitic plant Striga hermonthica is a severe threat to food security in sub-Saharan Africa, impacting the production of the major staple crops pearl millet and sorghum, equating to 7 - 10 billion $ losses.
