33
Q

The art of joining parts of plants together in such a manner that they will unite and continue their growth as one plant

A

grafting

34
Q

A type of repair grafting in which seedlings or suckers at the base of the original tree are grafted into the trunk to provide a new root system for a tree with damaged roots

A

Inarching

35

36
Q

Between individuals of different taxonomic families

Rootstock

43
Q

The upper portion or top of a grafted plant

A

44
Q

Changing the scion variety or cultivar by grafting onto usually established plantings or rootstocks for the purpose of replacing undesirable cultivars, establishing pollinators, or several scion cultivars on one stock

45
Q

The last stage of micropropagation in which the delicate new plant must be kept in an environment with high humidity and protection from pathogens

A

Acclimatization

46
Q

58
Q

Aerial orchid plantlet

A

Development of new plants in artificial medium under aseptic conditions from very small portions of plants; can be an asexual or sexual form of plant propagation

A

Micropropagation

61
Q

A term for a growth form in orchids in which there is only one main stem arising directly from the roots

A

Monopodial

62
Q

The stage of micropropagation in which plantlets are cut apart and placed on new media with a high cytokinin:auxin ratio so that new axillary or adventitious shoots can form

A

Multiplication

63
Q

A plant with multiple copies of its DNA in each cell (3 or more)

A

Polyploid

64
Q

The stage of micropropagation in which new plantlets form roots prior to being removed from the tissue culture environment

A

Pretransplant

65
Q

Stem tissue of sympodial orchids used as food and water storage; a type of geophyte found only in orchids
