YellowGrove isn't monopodial?

Post by Eastlandia »

Ok Bamboo Web,
I washed off a dead rhizome section of P. aureosulcata and noticed something odd. I could be completely wrong but ill still say it anyway: When a monopodial bamboo, that is a running bamboo, puts up a shoot, the roots that sometime form on the nodes/base of that shoot can?t become full size rhizomes. I know I have heard that from a book somewhere?
This is just another clue to me that running bamboos have to of come from clumping bamboos in the distant past?.just look at a Yushania!

Blue Arrows = shoot buds (now shoots)

Brian, what's interesting to me is that the rhizome coming from the larger culm, seems to have come from a bud at the base of the culm, which helps to illustrate what Phil was saying about 'living sticks' eventually producing new growth. Your photo shows the only way that I could envision this happening, by a bud at the culm base such as in a clumper, rather than a new bud being formed somewhere else along the rhizome.

Eso es muy interasante!

Ok, the above pictures are somewhat hard to see, but both of the Orange arrows point to places where Full Size Rhizomes came off a Culm. maybe this is not very rare after all. And dont tell me no one has washed off and cleaned rhizomes themselves, its the most fun, somewhat dirty, wastful, time-consuming, pointless thing you'll ever........ yah, forget it -Eastlandia :)

Hi, It's a very interesting pic and I'd just like to check out a few points;

The lower culm looks perfectly normal, with a rhizome coming from a bud and then the nearest bud on the new rhizome turning into a culm and carrying on.

The higher culm dose look somewhat strange :shock: but if you look closely the old rhizome did not produce a culm, it's too far away. If the shoot came from the old rhizome it would be nearer, it looks to me like another rhizome came from the bud with a very close shoot to the old rhizome. Now normally that rhizome Carry's on like the lower one, but here it dose a about turn and Carry's on on a different angle.

'If' it was produced on a new rhizome, although very short , the rhizome would have the capacity to grow on as shown, although something made it change direction( rocks/barrier).

Some phyllostachys here are so tight in their habit that when dividing you cannot see any rhizome at all, it there but so small you swear it was a clumper.

It's so hard to properly tell from one pic but I'd though I'd have a go anyway :roll:

Me again :D

Also, the rhizome size dosen't matter when it comes to shoot size, large shoots can be produced from quite small rhizome and also the reverse.

I've also seen it change size along the lenght too, probably responding to conditions.

I think there's too many questions regarding this plant :oops:

Mark, Im pretty sure that the 'clum your talking about is not a culm but a "chopped off" rhizome. in the division, this is where the blade cut. and it just happened to cut right on the two branching rhizomes. Nice pic -Eastlandia
