Germination Stage Water Scarcity in Bread and Einkorn Wheat
Öz
Germination (GR, %) and power (GP, %) rates, coleoptile (CL,
cm), shoot lenght (SL, cm), and root (RL, cm) length, shoot/root length ratio
(SRLR), root fresh weight (RFW, mg) and dry (RDW, mg) weight, and root
fresh/dry root ratio (RFDWR) of 12 bread and 10 einkorn wheat genotypes were
investigated under 7 drought stress levels. SL and SRLR in the study
were the most sensitive traits and followed by CL and RL. The mean performance
of all traits was worsened starting at various stress levels. The highest percent
reduction was in SL (100.00%), SRLR (100.00%), and RL (99.07%), and the lowest one
was in GP (55.9%). The common applied drought tolerance indices grouped the entries as tolerant, moderate, and susceptible. Einkorn
populations from higher rainfall Blacksea region responded worse under drought stress
than bread wheat cultivars, which were improved for drier or relatively drier Central
Anatolia, Sub-Marmara, and Thrace regions.
