Abstract:
The 22 parts of dried pepper varieties were used as test materials,and the 150 mmol?L-1 NaCl solution with low temperature of 18 ℃ was used as the stress condition.The seed germination potential,germination rate,germination index and the relative function values of each index were used.The cold tolerance and salt tolerance of the tested varieties during the germination period were evaluated.The results showed that the germination potential,germination rate and germination index of different pepper varieties were significantly different under stress conditions.These indicators could be used to identify cold tolerance and salt tolerance between varieties,and 22 parts of dried pepper varieties were synthesized by membership function.After evaluation,cluster analysis was carried out to select three varieties of dried peppers with good cold tolerance and salt tolerance,such as ‘Yufengyuan No9’‘Shaanzaohonghong’‘Zhenfengyuan Red Crown’.
