Question

what is grain filling and grain retention??

Answer 1

extend grain filling duration and thus increase yields in cereal crops. We found that wheat (Triticum aestivum) NAM RNAi plants with delayed senescence carried out 40% more flag leaf photosynthesis after anthesis than control plants, but had the same rate and duration of starch accumulation during grain filling and the same final grain weight. The additional photosynthate available in NAM RNAi plants was in part stored as fructans in the stems, whereas stem fructans were remobilised during grain filling in control plants. In both genotypes, activity of starch synthase was limiting for starch synthesis in the later stages of grain filling. We suggest that in order to realise the potential yield gains offered by delayed leaf senescence, this trait should be combined with increased grain filling capacity.

Answer 2

Grain filling and Grain retention:

• Grain filling refers to the stock of grains filled in the storage for their consumption and later use. Filling simply means to fill.  
• Grain retention is the continuous consumption of grains over time. Retention simply refers to the use of something in possession.

• Grains are important for the economy of the country. Our entire population depend on it.
• Both grain filling and grain retention are integral part of a country’s economy and is the main consumption unit.
