Abstract :
IN Order to investigate the effect of water stress and application potassium nanofertilizer on mother plant on germination components of quinoa seed (Chenopodium quinoa Willd), an experiment with two water stress factors at four levels (distilled water (control), -0.3, -0.6. And -0.9 MPa) using polyethylene glycol and two types of seeds obtained from field experiments (pre-treated) in a completely randomized design with four replications in a petri dish. For this purpose, seed samples were collected from two field experimental treatments (1- received nanopotassium fertilizer for field seeds and 2- field seeds without receiving nano-potassium fertilizer). The results showed that with increasing stress intensity, the germination percentage was significantly reduced and from 91.0% in the control treatment to 77.1% in severe stress conditions. With increasing stress intensity, the germination value was significantly reduced and from 1184 in the control treatment to 784 under severe stress. The longitudinal index of seedling vigor increased from 1411 in the control treatment to 1032 in severe stress conditions. Longitudinal index of seedling vigor in seeds treated with (1204) was significantly superior to untreated seeds with (1175). There was a significant difference between the average daily germination of treated seeds (11.6 days per seed) and untreated seeds (10.5 days per seed). Thus, application of potassium nanofertilizer on mother plant improved the germination components of quinoa seeds and their initial seedling growth.
