Understanding Source-Sink Dynamics in Wheat
Wheat is generally known as sink-limitation during the grain-filling period. First, let’s explore the definition of source-sink limitation. The source-sink relationship and the regulation of carbon allocation are determining factors in crop yield. The growth of crops can be restricted by the assimilate availability in specific crop organs or by the ability of those organs to utilize assimilates. In the former case, we refer to it as source-limitation, and in the latter case, it is known as sink-limitation. The causes…
