In the recent Stargate SG-1 two-parter Heroes, can you explain what is going on with the plant life on the planet visited?

In Part One, an SG team arrive on a planet and it is the middle of summer. The trees are in full bloom. However in Part Two, when the team is under attack on the planet, we see wounded soldiers on the ground and it seems to be autumn. There are brown leaves all over the place and the trees are bare.

What is going on?

Yours,

William Wilkins

In science fiction, we have witnessed many and various life cycles on strange alien worlds. For example, seasons on the planet Solos in the Doctor Who serial The Mutants last for hundreds of years, whereas the world of Priplanus in Lost in Space moves from arctic winter to blistering summer in a matter of hours.

Even though the plant life on P3X-666 in Heroes very likely originated on Earth, I would suggest that it has adapted or been modified to suit the planet's alien orbital path so that seasonal changes take place over mere hours or days, rather than months.
