The present study aimed to investigate the seed germination of a rare and endemic species Rosa iliensis Chrshan., collected in the floodplain of the Ili River in Balkhash district of Almaty region. The effects of seed pre-treatment like cold stratification and seed germination conditions were investigated using conventional germination methods.
R.iliensis fruits from natural populations were collected in mid-August 2024, then were dried for 2 weeks, and stored in paper bags at a temperature of +4℃. The fruits contained from 12 to 22 seeds depending on the fruit size. The seeds color is pale yellow. The average length (3.4±0.4 mm) and width (1.7±0.2 mm) were measured, and the weight of 1000 pieces of seeds (4.66 g) was determined on the seed analyzer MARViN ProLine II. To determine the duration of cold stratification, R.iliensis seeds were treated with a weak solution of bleach "Belizna" 1:1 for 20 minutes...
