Some of you are probably aware of my fondness for seeds -- and, especially, for seed-grown plants; and here is a selection of Heliamphora, sown 15 June and an example of some grown in vitro from 2009. I have another batch (in the fridge, next to my Guinness) ready for culturing this coming Monday; and I will update this post next week.
It may seem contradictory to some to also be fond of tissue culture or micro-propagation; but it is not necessarily the case. Often, when I obtain "valuable" seed, I like to spread the risk (especially considering their potential age and sundry, ugly issues with Customs); some are sown conventionally; others treated with gibberellic acid; and others are germinated aseptically, only to be planted in compost within a few months. I generally don't multiply plants in flasks -- the most common use of tissue culture. So, one still has seed-grown plants; it is only that the germination of some of them have occurred in TC media; and it is then no different from those who do so with seed in wet paper towel or water.
For the few to one who happens to be interested, my preferred TC media for Heliamphora is 2/3 Knudsen C; 0.1mg/l NAA; 25 grams sucrose; 1 ml/l PPM.
