Irises have high ornamental values because of their decorative flowers and the elegance of their elongated leaves ( Roguz et al., 2020 ; Xu et al., 2017 ). For example, Iris sanguinea has a blue flower color that offers great potential for
Iris is the largest genus in the family Iridaceae and comprises about 300 species of perennial plants around the world with a cultivation history dating back to 2000 bc ( Jeknić et al., 2014 ; Wilson, 2011 ; Zheng et al., 2017 ). It is widely
Bearded iris ( Iris × hybrida Hort.), characterized by a thick and bushy “beard” on three falls (lower petals), refers to the large artificial hybrid population in the Iris genus. They have extraordinary prevalence and great commercial value as
Iris , a genus of 300 species, is one of the most popular ornamental perennials in the Northern Hemisphere ( Austin and Waddick, 2005 ). However, a distinct drawback of this genus is that most species will be deciduous without any aesthetic quality
Iris yellow spot virus (family Bunyaviridae , genus Tospovirus ) was first reported as Tomato spotted wilt virus in southern Brazil in 1981 affecting onion scapes (de Avila et al., 1981 cited in Gent et al., 2006 ) but later confirmed as a new
degree of single centers ( Cramer, 2006 ; Gamie et al., 1995 ; Wall et al., 1996 ;). Iris yellow spot virus (IYSV) causes seed stalk and leaf tissue necrosis and has recently been recognized as a serious disease of onion ( Gent et al., 2006 ). IYSV was
conveniently and comprehensively determined, in a more timely manner, by electrophysiological parameters than by the measurement of intracellular energy and charge state ( Anderson, 1980 ; Ramage, 2002 ). Iris pseudacorus and Iris japonica are both fast
Because of their showy, colorful flowers and sword-shaped leaves, TB iris ( Iris germanica L.) has potential as a specialty cut flower. Tall bearded iris plants are composed of four parts: basal sword-shaped leaves (usually called fans
( Tulipa hybrids) and dutch iris ( Iris × hollandica ) are popular cut flower species commonly produced during cool spring seasons. These species have a relatively short storage and vase life ( Dole et al., 2017 ). Forcers can achieve a longer stem length
Abstract
Seeds of Alaska iris, Iris setosa Pall. ssp. interior (Anders.) Hult., were collected from wild stands near Fairbanks and subjected to the following treatments: 0 or 125 days of stratification; 24-hr soak in water or 1000 mg·liter-1 gibberellic acid (GA3); alternating (25°/10°C) or constant (21°) temperatures; and germination in darkness or light. After 7 days, germination was best (95.0%) with stratified seeds that were soaked in GA3 and germinated at constant temperatures in the dark. A greenhouse study in which stratified seeds were soaked in water or GA3, sown in a commercial peat and vermiculite seed germination mix, and germinated beneath clear or black plastic confirm ed that germination was highest (64.4%) and most uniform (83.3% filled container cells) with the com bined treatments of GA3 and darkness.
