NaOH Scarification and Stratification Improve Germination of Iris lactea var. chinensis Seed

NaOH Scarification and Stratification Improve Germination of Iris lactea var. chinensis Seed

Iris lactea seed is characterized mainly by physiological dormancy. Two experiments were conducted to investigate the effect of NaOH treatment and stratification on Iris seed germination. In Experiment 1, seeds were treated with 14.38 M NaOH for 0 to 28 hours. In Experiment 2, NaOH treated and nontreated seeds were stratified under 7 °C and moistened condition for 0 to 40 days. As results, NaOH...

Effects of scarification and stratification on seed germination and dormancy of turgenia latifolia, cuscuta SP and sophora alopecuroides in different temperature regimes

Effect of Seed Scarification on in Vitro Seed Germination of Abrus Precatorius L

Abrus precatorius is the native plant of India and used in many ways in the Indian Ayurvedic system of medicine. This seeds of the species is dormant due to hard seed coat. So the aim of the study is to remove seed dormancy and enhance germination capacity within a short period. To overcome the problem of dormancy, seeds were scarified by seed scarifier, sand paper, hot water treatment, DMSO an...

Ecology of seed dormancy and germination of Carex divisa Huds.: Effects of stratification, temperature and salinity

Carex divisa is a patrimonial rhizomatous species and acts as an important component of grazed wet permanent grassland on the French Atlantic coast. This study treated three storage regimes (wet-cold, dry-cold and dry-warm), burial in soil, fluctuating temperature and salinity on seed germination of C. divisa. The seeds were dormant at maturity. No seed germinated after 2 and 6 weeks of dry sto...

Overcoming dormancy in New Mexico mountain mahogany seed collections

Mountain mahogany (Cercocarpus montanus Raf) is a useful reclamation species because it can occupy and improve poor soils. Literature regarding seed propagation of tbis species is var· ied and often contradictory, recommending stratification dura· tions of 14 to 90 days, and sulfuric acid scarification durations of none to 60 minutes. To assess variability in propagation require. ments among se...
