Vigor of White Lupin

Lupinus albus L.

The vigor of white lupin determines the biological quality of seeds and their ability to produce uniform emergence under field conditions, directly correlating with field germination and seedling stress tolerance.

In the reference 18 varieties crop White lupin, where this is mentioned in the description.

To evaluate the seed vigor of white lupin, the sand germination method at planting depth is used, recording the number of emerged seedlings on the 10th day, as well as morphophysiological analysis in rolled filter paper to categorize seedlings into strong and weak based on root condition and shoot length.

Physiological studies link the seed vigor of this crop to the accumulation of specific proteins, such as γ- and δ-conglutins, as well as the metabolic intensity of mitochondria during germination. High vigor indices indicate a slower loss of seed viability during storage.

This index is not strictly a varietal trait, as it is heavily dependent on the conditions during crop formation, the degree of seed damage during harvesting, and storage conditions. Laboratory evaluation of seed vigor is used in seed production alongside standard quality indicators to predict crop productivity.
