Current through Register Vol. 49, No. 6, June, 2024
The production of blackberry nursery stock is an important
				industry in Arkansas. Diseases such as rust, anthracnose, crown gall and
				viruses, as well as pests such as cane borers and nematodes pose a threat to
				the blackberry nursery industry. To prevent the spread of these problems by
				nursery stock, the following certification regulations shall apply to the
				production and sale of certified blackberry nursery stock in Arkansas.
I.
Definitions
Board
means the Arkansas State Plant Board.
Blackberry
means cultivated
Rubus
species and related plants that are considered blackberry
				botanically.
Cane cutting
is a cane section of two or more
				nodes or buds (length 4-6 inches) to be transplanted to produce a plant.
Crown is the persistent (perennial) base of the plant; the
				junction between canes and roots (some varieties have buds that arise primarily
				from the crown).
Director
means the director of the State Plant
				Board or his duly appointed representative.
Hardwood cutting
is taken from a mature woody stem
				for the purpose of propagation.
Indicator plant
means any herbaceous or woody
				plant used to index or determine virus infection.
Indexing
is a procedure to determine virus or
				other pathogen infection by inoculation from the plant to be tested to an
				indicator plant (grafted onto plant to be tested) or by any other approved
				method.
Mericlones
are plants clonally propagated from a
				single meristem tip.
Micropropagation
is plant multiplication
in vitro.
Blackberry is propagated in tissue culture by
				aseptic transfer of meristem tip cultures to produce Nuclear stocks.
Nodal cutting
is a cane cutting with a single node
				to produce a plant.
One-year-old plants
means well rooted plants that
				have developed during one growing season.
Primocane
(succulent plants) is the current
				season's growth that develops from root or basal crown buds.
Root cuttings
is a root section with one or more
				buds.
Softwood
cutting is taken from a green, immature,
				actively growing stem of a woody plant during spring or early summer for the
				purpose of propagation.
Succulent plant
means a small, actively growing
				plant that is developing from root buds, not having passed through a dormant
				period.
Virus infected (affected)
means presence of a
				virus (es) or yellows disease agent in a plant or plant part. The word "virus"
				shall be used hereafter to include yellows disease.
Virus-like means a disorder of genetic or non transmissible
