     (("Aseptic shoot tip propagation" means aseptically removing a vegetative shoot tip from growth arising from a dormant cutting from a foundation plant or from green growth (i.e., softwood) from a foundation plant during the growing season and aseptically transferring this shoot tip to a suitable vessel containing an appropriate culture medium.))

     "Indicator plant" means any herbaceous or woody plant used to index or determine virus infection.

     "Mother vine" means a grapevine used as a source for propagation material.

     "Off-type" means appearing under visual examination to be different from the variety listed on the application for registration and certification, or exhibiting symptoms of a genetic or nontransmissible disorder.

     "Registered block" means a planting of registered grapevines maintained by a nursery and used as a source of propagation material for certified grapevines.

     "Registered vine" means any vine propagated from a foundation block approved by the director, identified to a single vine source, and registered with the Washington state department of agriculture, in compliance with provisions of this chapter.

     "Tissue culture" means aseptically removing a vegetative shoot tip from growth arising from a dormant cutting from a foundation plant or from green growth (i.e., softwood) from a foundation plant during the growing season and aseptically transferring this shoot tip to a suitable vessel containing an appropriate culture medium.

     "Virus-like" means a graft-transmissible disorder with symptoms resembling a characterized virus disease, including, but not limited to, disorders caused by viroids and phytoplasmas.

     (2) The applicant must maintain records identifying the foundation source of registered vines and certified planting stock. The applicant must make these records available to the department upon request.

     (3) The applicant shall take suitable precautions in cultivation, irrigation, movement and use of equipment, and in other farming practices, to guard against spread of soil-borne pests to planting stock entered in this program. The applicant shall keep all registered blocks and certified planting stock clean cultivated except for approved cover crops.

     (4) Following notification by the department the applicant shall remove and destroy immediately any registered vine or certified planting stock found to be off-type or affected by a virus or virus-like disease or a quarantine pest.

     (((5) Registered blocks and certified planting stock must be located at least one hundred feet from any land on which noncertified or nonregistered grapevines have been grown within the past ten years. This does not apply to registered and certified stock grown in a fully enclosed greenhouse, screenhouse or laboratory provided the facility does not contain noncertified grapevines.))

     (2) With the exception of practices allowed in subsections (3), (4), and (5) of this section, registered plants must be propagated directly from cuttings taken from a foundation block.

     (3) Plants propagated from a foundation block by ((aseptic shoot tip propagation)) tissue culture and grown entirely under laboratory or greenhouse conditions may serve as a source of softwood cuttings or shoot tip culture used to establish a registered block or registered grapevines.

     (4) Registered grapevines may be propagated from other registered grapevines within the same registered block for the purpose of increasing the size of the registered block or for replacement grapevines, if the mother vine was propagated directly from a foundation vine.
