Cacti

Cacti

As the world becomes hotter and drier, we believe that catus will become increasingly important as ornamental bedding, potted, landscape and food crops.  Our work has focused on identifying the best cacti genera to introduce as new flowering bedding, potted and landscape plants.  Below, please find new research as well as recent background information on cactus production.

Propagation:
Micropropagation of cacti - a review
Tissue culture of ornamental cacti

Alterations in growth and crassulacean acid metabolism (CAM) activity of in vitro caultured cactus.

Environment:

Plant Growth Regulators:
Benzyladenine foliar sprays increase offsets in Sempervivum and Echeveria (Carey, Whipker, McCall and Buhler, 2008)

Nutrition:

Flowering:
Effects of day-length, radiation, flower thinning and growth regulators on Hylocereus and Selenicereus.
Photoperiod, irradiance, and temperature affect Echinopsis 'Rose Quartz' flowering (Erwin, O'Connell and Altman, 2016)

Grafting:
Production and breeding of cacti for grafting in Korea (Jeong et al., 2009)

Pests
Pest risk evaluation on cacti and succulents for light brown apple moth (LBAM): Can they be exempted? (USDA, 2015)

Disease:
Management of Fusarium wilt of lettuce (Gordon and Koike, 2015.  Crop Protection., 73:45-49.
​

Hatiora (Easter Cactus):
Daily light integral, prevernalization photoperiod, and vernalization temperature and duration control flowering of Easter cactus. (Rohwer and Heins, 2007)
Flowering spring cactus (Rohwer, Runkle and Heins, 2004)

​Ferocactus:
Influence of photoperiod on growth for three desert CAM species (Nobel, 1989)

Opuntia:
Influence of photoperiod on growth for three desert CAM species (Nobel, 1989)
