alocasia DNA


Dear Denis
f a diploid has say 10 pg of DNA per nucleus then a triploid will 
have 15 and a tetraploid 20 pg. The number of chromosomes is 
irrelevant as it only tells in how much pieces the total amount is 
divided. The method is usually not sensitive enough to reveal 
aneuploidy  ie a few chromosomes more or less. As it is for me 
about the same amount of work just send all ten you named. I only 
need a small amount of  fresh material being part of a leaf, petiole 
or root. Best is to wrap them in plastic, but dont close the bag else 
they will suffocate Dont use paper as it will dry them out too much 
Just send them to the adress below as: Herbarium material for 
Scientific study. No further paper work required So far it always 
worked Let me know in advance when you send them.
