Uniform and fast germinating seeds are of prime importance for agriculture. To improve the germination properties of seeds, different treatments called priming are used. These methods generally involve the controlled uptake of water by the seeds. To be able to understand the processes involved in different priming methods the aim of the research was to study the relationship between the methods of water supply, water uptake rate by seeds, seeds moisture content and germination of China aster ‘Jolanta’ and tomato ‘Janosik’ seeds. Seeds of these species were primed by: (i) soaking in excessive amount of distilled water for 0–1440 min in the ratio of seeds to water (v:v) of 1:3; (ii) soaking in limited amount of distilled water 10–1280 ml kg−1of seeds; (iii) matriconditioning in the ratios of 1:0.4:0.2–2.0 (w:w:w) for seeds, Calflo and water, respectively. The imbibed seeds were incubated for 1 day at 20 ◦C and seed moisture content was measured after incubation. Additionally, in seeds moistened up to 37% (China aster) and 35% (tomato), dynamics of water uptake were examined. Seeds, after imbibition and incubation, were dried to the initial moisture content (m.c.). Percentage of the germinated seeds, maximum germination (Gmax), time for the first seed to germinate (T1), time to reach 50% germination (T50), time between 10 and 90% of Gmax (T90–T10), at 5, 20 or 35 ◦C for the China aster seeds and at 15, 20 or 35 ◦C for tomato were evaluated(Badek et al., 2006).
種子發芽的快速和一致性對於農業是很重要的。為了提高種子發芽的特性，使用不同的處理方法稱為滲調。這些方法通常包括控制種子攝取的水量。為了瞭解有關過程研究不同的滲調方法，目的是研究供水方法之間的關係，中國翠菊 Jolanta 和番茄 Janosik 種子吸收水分的速率，種子水分含量和發芽。這些物種的種子滲調經由：（一）浸泡在過量的蒸餾水中0-1440分鐘，種子和水的比率為 1:3（V：V）;（二）種子浸泡在有限量的蒸餾水中10-1280 ml kg−1;（三）種子固調處理Calflo和水的的比值，分別為1:0.4:0.2-2.0（w：w：w）。種子吸水後在20℃中培育一天，培育後測量種子水分含量。此外，在種子浸潤達到 37％（中國紫苑）和35％（番茄），進行水分吸收動態的調查。種子吸水和培育後，將初始水分含量（m.c.）乾燥。種子發芽的百分比，最高發芽率（Gmax），最先發芽種子時間（T1）發芽達到50％的時間（T50），最高發芽率時間在10至90％之間（T90- T10），在5、20或35℃為中國翠菊種子，和在15、20或35℃的番茄進行試驗(Badek et al., 2006)。
