Twelve bread and ten einkorn wheat genotypes were used as plant material and seven drought stress levels were applied based on a three-replicate factorial restricted randomized block design in order to investigate their effects on germination rate (GR), germinating power (GP), coleoptile
length (CL), shoot length (SL), root length (RL), shoot root length ratio (SRLR), root fresh weight (RFW), root dry weight (RDW), and root fresh dry weight ratio (RFDWR) during the year 2014-2015.
According to Cothren and Oosterhuis (2010), the root growth is inhibited by auxin in proportions promoting the stems and coleoptile
elongation, which could explain the shoot growth stimulation in contrast with the root inhibition, as demonstrated in Table 2.
Seedlings with root length of 3-5 cm and coleoptile
length of about 2 cm were ideally selected for colchicine and pendimethalin treatments.
According to data analysis, significant differences were observed between treatments (Table 1 and 2), except for panicle length (PL), coleoptile
length (CL) and radicle length (RL).

and to test the phytotoxicity of ethyl acetate extract on the germination, growth and size of the metaxylem cells of sesame seedlings.
The results presented in the figures for Vitron variety showed that the coleoptile
recent seed is more developed with a maximum length of 169.
An increased number of cell layers in the scutellum and other stages of embryonic development were observed when the coleoptile
emerged (Figure 5F).

2004), even the genetic variation of aphid aggressiveness has been studied among biotypes by means of the coleoptile
tests (Gimenez et al.

growth (Table 1).
