Try these links:
The second link is a factsheet mainly relating to ginseng but the introduction looked like it may be helpful for formulating a general definition.
Hope this helps.

how about anything other than a pest or disease that causes a plant to malfunction, usually something on the lines of pollution or climatic factors?

Dear clare, the answer to your query,as defined by the RHS encyclopedia of gardening is as follows...is a very long answer
Physiological disorder
Plant disorders usually result from nutritional dificiancies or from unsuitable growing media, or storage conditions. An inappropriate temperature range, inadequate or erratic water or food supply, poor light or unsatisfactory atmospheric conditions may lead to phsiological disorders. Problems may also be caused by deficiencies of the minerals and salts that are essential for healthy growth.
warned you it was a long answer....good luck with the course.

Isnt there anything at all in your course materials which relates to physiological disorder? I have done three Open University courses and you can usually find the information is somewhere within the course materials. The problem is we students tend to skip over some otherwise important aspects of a course and miss the points we are expected to answer. Suddenly its all there in front of you, questions are not usually targeted at something which is not entirely in the course. I congratulate you for looking for this information elsewhere, but those two words should be somewhere in your materials, if not then you are on the right track doing your research! I wish I could help in this context, but Im not sure what apects you have been studying. Good luck with the course, I rather suspect the next Alan Titchmarsh is due soon!

Hello clarerat, the definition that we were given is:
'A physiological disorder is any abnormal symptom in a plant *not* involving a pathogen (fungus, bacteria, virus) or pest’.
Short and easy to remember.
Good luck on the 9th, by the way :-)

Hello clarerat!
Great to see that there's others doing an RHS course, I'm also preparing for the 9th of March! I haven't seen or met anybody until now who has done or is planning to do an RHS exam!!!
A good definition there, Miranda, thanks a lot =)

Thanks, Becky.
Good luck to us all for the 9th!
Maybe we should start an exam thread...

Yes , I would love to see a few of the questions and answers, a new window as it were.Is practical gardening part of the syllabus, and are shortcuts (for doing the same job) taught.Good luck for the 9th.

I'm sure I can remember someone asking the same question (physiological disorder) on the board last year! Obviously a regular question on the course.

Hello, Ken. Yes, practical gardening is part of the syllabus, though the exam is written and theory based. We've done one practical session each week, much of which has been based on propagation or shrub and tree identification walks.
Shortcuts haven't been covered - it's all done by the book - though methods such as gibberelic acid soaks for breaking seed dormancy do get discussed.
I have quite a lot of past exam questions, so if you want some let me know.

Hello Clare/Miranda...when I say shortcuts I mean an alternative way of doing the same job...e.g. brushing a wet lawn to dry it off before cutting or as mentioned in another post the many ways of treating weeds. Am always forgetting the different strands of horticulture, nurseries, tree surgery, even smallholding and flower arranging.There never are ideal conditions outside, for example, too hot to water, but ideal for hoeing, too wet to mow but ideal for mulching,too windy for spraying but ideal for drying off . I sometimes think the teachers live in an ivory tower.

Ken, see what you mean now by short cuts.
Yes, in all the classes when cultivation is being discussed there has always been full input from class members, with many of us describing and comparing our own methods. One example is for stratification of seeds - why put them in the fridge when you can leave them outside for the winter and save fridge space? One class member, an ex-farmer, said that when they sowed lettuce seed it was always done in the middle of the night because it was cooler then.
I know what you mean about teachers living in ivory towers, but I have been lucky enough to be taught by someone who also runs a small nursery and is extremely practical. It's her teaching, as well as the material itself, that has made the course so enjoyable.
