The aim of the experiment was to determine<br />physiological maturity of Pimpinella pruatjan seed and to study its morphological structures.<br />Observation and sampling using one hundred plants with four replications. Results of the<br />experiment showed that the physiological seed maturity on the first and third umbell of P.<br />Pruatjan was achieved at 7 weeks after anthesis, and physiological seed maturity on the<br />second umbell was achieved at 8 weeks after anthesis. Seed dry weight on the physiological<br />seed maturity on first, second and third umbells were 166,87; 158,20, and 141,35 mg/100<br />pericarp, respectively. Germination percentage and germination speed on the first, second<br />and third umbells were 5,75 % and 0,22 %/etmal; 22,75 % and 0,94 %/etmal; 10,50 % and<br />0,38 %/etmal, respectively.<br /></span><span class="fontstyle2">Keywords</span><span class="fontstyle0">: flowering, pruatjan, seed quality, morphology</span> ER -
