AB  - Buaraştırmada; lif bitkisi ve tıbbi bitki olarak kullanımının yanı sıra, sebzeolarak da tüketim değeri olan molehiya (Corchorusolitorius L.) bitkisinintohumlarında, dormansiyi kırmak için farklı tohum uygulamalarınınçimlenme ve çıkış üzerine etkisi amaçlanmıştır. Bu amaçla sterilizasyonuyapılan tohumlara; kaynayan su (95 ºC; 10 ve 30 saniye, 1, 5 ve 10 dakika),sıcak su (80 ºC; 5, 10, 15 ve 20 dakika), sülfürik asit (% 98’lik; 5, 10, 15,20, 25 ve 30 dakika) ve ön soğutma uygulamaları (4ºC; 2, 3 ve 4 gün) yapılmıştır.Denemeler; laboratuvar ortamında, 4 tekerrürlü ve her tekerrürde 50 tohumolacak şekilde tesadüf parselleri deneme desenine göre yürütülmüştür. Elde edilen sonuçlara göre; çimlenme oranı % 0.00-97.00, ortalama çimlenme süresi0.00-3.98 gün, çimlenme indeksi 0.00-46.89, çıkış oranı % 0.00-82.00, ortalamaçıkış süresi 0.00-7.52 gün, çıkış indeksi 0.00-18.70, hipokotil boyu 0.00-1.79cm ve kökçük boyu ise 0.00-4.28 cm arasında değişim göstermiştir. Çimlenme veçıkış parametreleri bakımından en başarılı uygulamalar; ön soğutma, sülfürikasit (5 ve 10 dakika) ve kaynayan su (95 ºC, 10 saniye) uygulamaları olmuştur.Çalışma sonucunda, Corchorus olitoriusL. tohumlarında dormansiyi ortadan kaldırmada, ekimden önce tohumların 2 günsüreyle nemli ortamda soğukta (4 ºC) bekletilmesinin pratikte de rahatlıklauygulanabileceği sonucuna ulaşılmıştır.

N2  - In this study, the effect of different seed applications on germination and emergence in order to break dormancyof the seeds of molekhia (Corchorus olitorius L.) which is used as fiber, medicinal plant and consumed as a vegetable, wasinvestigated. For this purpose, sterilized seeds were exposed to boiling water (95 ºC; 10 and 30 seconds, 1, 5 and 10minutes), hot water (80 ºC; 5, 10, 15 and 20 minutes), sulfuric acid (98%; 5, 10, 15, 20, 25 and 30 minutes) and pre-cooling(4 ºC; 2, 3 and 4 days) treatments. The experiments were carried out according to randomized blocks trial design with 4replications and 50 seeds per replicate. According to results obtained, germination rate 0.00-97.00%, average germinationtime 0.00-3.98 days, germination index 0.00-46.89, emergence rate 0.00-82.00%, average emergence time 0.00-7.52 days,emergence index 0.00-18.70, hypocotyl length 0.00-1.79 cm and radicle length values varied between 0.00 and 4.28 cm. Themost successful treatments in terms of germination and emergence parameters were pre-chilling, sulfuric acid (for 5 and 10minutes) and boiled water (at 95 ºC for 10 seconds) applications. As a result of the study, in order to remove the dormancyfrom the Corchorus olitorius L. seeds, treatment of the seeds with pre-cooling (4 ºC for 2 days) in a humid environmentbefore sowing would be easily practiced.
