Primary physiological dormancy is a basic concept for courses that emphasize general plant propagation or specific courses in seed biology or technology. Primary seed dormancy is a condition where seeds will not germinate even when the environmental

, offshoots, or tissue culture, the vast majority of landscape palms are propagated by seeds. However, commercial production of many palm species is hampered by delayed and inconsistent germination. Such sporadic germination is often due to seed dormancy

Plants produce seeds to ensure the greatest establishment and survival success for future generations ( Stoehr and El-Kassaby, 2011 ). One innate mechanism to increase seedling success is seed dormancy. The critical function of dormancy is to

; Rumbaugh et al., 1993 ). Currently, the lack of successful in and ex situ germination resulting from seed dormancy limits its use in restoration. Few sources explore the dormancy mechanisms and methods that induce germination in Sphaeralcea spp. ( Page et

et al., 1993 ). Most buffalograss is commercially treated with KNO 3 followed by chilling to overcome dormancy ( Fry, 1995 ), which increases germination from 10% to 80% ( Riordan et al., 1997 ). Optimum spring seeding dates for buffalograss

Seed dormancy is an inherent adaptation in plants that delays the germination of newly dispersed seed ( Tarasoff et al., 2007 ) allowing germination to be temporally staggered. In restoration and re-vegetation with native groundcovers, seed dormancy

( Holzmueller et al., 2007 ; Thomas, 1969 ). Typically, C. florida is propagated from seeds, but the seeds usually develop strong dormancy ( Coartney et al., 1989 ), which may be a great challenge for seed reproduction ( Dirr and Heuser, 1987 ). Studied with

seeds are light-induced seeds with physiologic dormancy, and their dormancy can be broken by gibberellic acid (GA 3 ), cold stratification, and dry storage ( Liu et al., 2017 ). We have tested the seed germination of three species of Paulownia [empress

Seed dormancy refers to the state in which an intact viable seed does not complete germination under favorable conditions ( Finch-Savage and Leubner-Metzger, 2006 ). Normally, the dormancy is influenced by the embryo and its surrounding layers (e

Dormancy is a seed trait that prevents germination when conditions are favorable for germination yet the probability of seedling survival is low ( Baskin and Baskin, 2001 ; Fenner and Thompson, 2005 ). Five kinds of dormancy are currently
