Sports Scholars,
We run across definitions from time to time. Some seem incorrect because
of a word insertion or for some other reason. What have you found that
appears different?
1 A definition from American College Dictionary..a part of a plant that
shows an unusual deviation from the parent type ( plant) . I wonder if
an "usual" deviation therefore is NOT a sport?.
2. In one post I called a bud sport " a change in the appearance in the
part of the plant that sprouted from a bud." I referred to it as a
gardeners term but it is more than that. It is also used as a scientific
term by Botanists, Horticulturists, Plant Anatomists but not by
Geneticists strangely. I wonder what they have against the term?.
3 In an email from Holland on August 16, 1999 a definition is given as a
shoot differing from the mother plant irrespective of the cause. Now we
can think of several causes of shoots that may differ from the mother
plant, such as virus, damage of all sorts, differences due to cultural
factors , etc. So this definition has some weaknesses.
4. Hartmann ( of Kester and Hartman...the plant propagation authorities,
i.e. Plant Propagatin, Principles and Practices) in an early edition
describes a sport as a plant arising from a bud which is suddenly
affected by a change in the inheritable character that can be
perpetuated by asexual means. A little wordy but who dares to argue with
the experts who write textbooks for college use?
5. In a later edition Hartmann and Kester describes it as a branch which
shows changes in one or more inheritable characters that can be
perpetuated by asexual means. Are you thinking what I am thinking? Yes,
a division is a branch, so this definition is certainly accurate for
hostas.
What is your definition for a sport...technically, it is called a "bud
sport"?
