استجابة النقع بمستخلص (الأكاديان) في قوة بذور الحنطة تحت الأجهاد الملحي

Abstract

A laboratory experiment was carried out in the laboratories of (Seed Examination and Certification Department of the Ministry of Agriculture and Postgraduate Laboratories- College of Agricultural Engineering Sciences - University of Baghdad) in 2021-2022, to determine the best combination of acadian concentration (seaweed extract) 0, 1500, 2000 and 2500 mg/L , under three levels of salt stress 5, 10 and 15 dS/m as well as control treatment through traits of seedlings of wheat (cv. Tammuz). A factorial experiment was applied according to a completely randomized design with three repetitions. The seed soaking treatment was superior to the concentration 2500 mg/L in the first count, final count, radicle length, stalk length, seedling strength index, and seedling dry weight. The salt tensile level 15 dS/m negatively affected the averages of all studied traits. The combination 5 dS/m × 2500 mg/L recorded a significant superiority in (first count, radicle length, stalk length, seedling strength index). A combination of 0 NaCl × 2500 mg/L significantly in the final count.
