Generally speaking, the letters used to represent cross breeding in Punnett squares indicate the characteristic being bred for. In this case, T would represent the tall plants, and S would represent the short plants. Cross-bred plants would most likely be represented by TS.
Any letters can be used, but typically "T" is used for tall and "t" is for short. Letters are usually chosen by using the first letter of the characteristic being described, and the upper case represents the trait being dominant. Lower case represents the trait being recessive.
True breeding tall plants would be TT and true breeding short plants would be tt, so TT x tt would illustrate the crossbreeding.
TT for the homozygous tall parent, tt for the homozygous short parent and Tt for the heterozygous offspring.

Yes, it is true. Mendels principles apply to anything and everythin that is living.
Morgan's research lead to one of the common diagrams used to predict the result of crossbreeding, the Punnett square.

Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.

There were three times as many tall plants as short plants.

Three times as many shorts plants as tall plants.
