this appears in a text about genetics and I don´t know which could be the right translation: “shorter stature, dark and stay-green nature, and late flowering, and some of them had a much smaller number of seeds”

 

I'm not sure what the translation would be as I'm not quite sure what it means in English. Dark and stay-green nature could mean that the rice plant has the tendency to stay dark green longer.

 

thanks, that would be useful.
if any other translation is posible please tell me.

 

This is just a guess...

"...con tendencia a mantenerse verde y oscuro por más tiempo..."

Qué te parece?

 

me parece una muy buena posibilidad.. muchas gracias
