Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This research aimed to determine the seed storage potential and relative storability of six wheat varieties under both natural and accelerated ageing conditions. This study sought to identify wheat varieties with good and poor storage potential and investigate the impact of ageing on seed quality.

• Seed storage potential of different wheat varieties
• Impact of natural and accelerated ageing on seed germination and vigour
• Identification of wheat varieties with good and poor storage potential
• Comparison of seed storability under natural and accelerated ageing conditions
• Effects of ageing on seed structure, biochemistry, and genetics

Zusammenfassung der Kapitel (Chapter Summaries)

The research methodology involved collecting seed material from six wheat varieties and storing them under ambient conditions. Accelerated ageing was also employed to assess seed storability. Standard germination tests were conducted using ISTA seed testing rules, and the vigour index was calculated.

The results revealed that different wheat varieties exhibited varying storage potential, with C-306 showing a decline in germination percentage below minimum seed certification standards after 18 months of ambient storage. PBW-502, on the other hand, maintained a higher germination percentage. Similarly, accelerated ageing demonstrated variability in seed storability among the varieties, with PBW-502 again showing better storage potential.
