albostriata, (stri)

Habit:
Leaves: The same spotting as in the cotyledones is seen in very young leaves in the vicinity of the growth cone.
Seedlings:
Cotyledones: Completely white at germination. Later they develop some or many little green spots which form a very regular whitegreen spotting.
Hypocotyl: Completely white at germination.
Inflorescence:
Flowers:
- Upper lip:
- Lower lip:
- Bumps:
Seed:
Roots:
Remarks: The spotting is the result of back mutation to stri+ (see also pal-rec). This backmutation may appear at such an early stage that whole leaves stem sectors and whole stems show a normal green. There are heterozygyous in most cases, very rarely homozygous. Older leaves often appear completely green macroscopically. The appearance of the first green spots and the amount of spotting vary greatly. Often seedlings remain 8 to 10 days after germination completely white, often they are almost green after the spreading of the germination. stri+ is completely dominant over stri. Vitality and fitness vary with the amount of the spotting.
