Plant material. One-month-old ex vitro–grown young plants of Paphiopedilum callosum cultured on fern fiber in a greenhouse (Tay Nguyen Institute for Scientific Research, Dalat, Vietnam) that were ≈1.5 cm in height were harvested from donor plants and

grasses at test sites in Fargo and Mandan, ND. The grasses were watered to prevent stress during the first growing season, but did not receive any other care other than weed control. Silver banner grass and big bluestem showed the most potential. Fern Leaf

humidity. At higher temperatures (assuming a constant water supply where water is not limited and constant light intensity) we gain a higher VPD than at lower temperatures, and we expect a growth reduction as described for ‘Boston’ fern by Mortensen (1986

perennial weeds. During the final harvest, all spears that had emerged were snapped off at soil level to reduce exposure to these herbicides. The asparagus fern and weeds were allowed to grow for the rest of the season. Infestations of common asparagus

since 1961 ( Wang, 1970 ). The mother stalk is cut twice annually (usually in February and July). A total of three to eight vigorous stems per crown depending on the plant’s age are selected and allowed to develop into leaf-like cladodes called fern that

represents 16 southern states. The initial ornamental plant research and educational efforts conducted under the best management practice (BMP) umbrella in Florida began in the 1980s for the leatherleaf fern ( Rumohra adiantiformis ) industry. Those efforts

inexpensive. Recently Wilson et al. (2002) and Drost (2005) suggested the use of a refractometer for measuring root soluble carbohydrates in asparagus. The authors stated that growth of spears and ferns during the crop's annual cycle is associated with a

time points after plants were sprayed with pesticides, and individual plants are scored according to a severity scale. A representative example of phytotoxicity assessment in a variety of fern species (Polypodiopsida) used the following scaling ( Stamps

invasive species, japanese barberry and winged euonymus. American filbert, buttonbush, northern bush honeysuckle, sweet fern, and sweet gale performed as well as the invasive species. Steeplebush did not perform as well due to powdery mildew and less than
