Rooting Sida Cordifolia..
« on: February 25, 2010, 05:36:22 AM »
Well, it is official I've got spring fever.
 I have noticed it is getting warmer -- slightly, but it is.

So... I'm pulling out some of the plants that have been crying for help, killing off the aphids, giving them more light, and germinating more sida cordifolia. I've been searching on how to root these guys, some sources say it is possible, but they are few and far between so I don't know if it is possible.

I hope it is, because it is a tall lengthy plant -- at least in my experience, and upon cutting it it bushes out more, and then grows upwards. If the cuttings are able to root, I can say goodbye to the long process of trying to germinate th seeds, and wait for the plant to get large enough to pick at...
A huge bonus to rotting the cuttings obviously is the amazing rate at which I'll be able to propagate it. I have about ~ 5 healthy stems at the moment, so obviously 5 -> 10 -> 20 -> 40... + whatever seeds I collect.

Here is a bit of information that I've got on rooting roses, which if it doesn't come in handy for the sida, it is still interesting to me at least -- though, I kind of get the feeling a lot of you guys are not to interested in plants - which is to bad as they offer a range of all sorts of different precursor chemicals for whatever. Though -- not in any great quality or quantity.


Well -- anyone know more about the rhizocaline mentioned in the pdf? or more about rooting Sida Cordifolia? I've found this about sida.. but I am not sure how accurate it is. Once my Sida plants start looking better then they are at the moment, I am going to use them to see if they will root, as the ones I am trying to root at the moment were/are nearly dead.  

Also -- one of my little plants is deciding it is going to flower! :D

Propagation by Cuttings
Sida fallax can be grown from cuttings. Criley recommends using a rooting hormone of 2,000 parts per million (ppm) indolebutyric acid (IBA) in either a liquid or a talc dust form. He suggests either 1 part coarse perlite to 1 part vermiculite or 100% vermiculite as a rooting medium and rooting the cuttings under 30% shade. He cautions, however, that extremely wet conditions, such as often found when using intermittent misting systems, causes leaf drop and poor rooting.

Boche reports 85% success rate using stem and tip cuttings grown in 50% shade using a medium of 3 parts peat moss to 1 part vermiculite. Stratton reports 80 to 90% success rates from cuttings but does not detail the procedures used. (Boche 1992; Criley 1999; Stratton 1998)

IIRC, the  rhizocaline is supposed to make IAA more effective... and so likely IBA more effective as well.

Abstract  A method was developed to initiate multiple shoots from mature nodal explants of Sida cordifolia Linn. High frequency of regeneration was achieved on Murashige and Skoog (MS) medium supplemented with 2.0 mg l?1 6-benzylaminopurine, 0.5 mg l?1 ?-naphthalene acidic acid, 1.0 mg l?1 adenine sulfate, and 10% (v/v) coconut milk. Multiple shoots were initiated within 21 d and the above media was capable of inducing the formation of more than 20 shoots from each explant. Regenerated shoots were successfully rooted on half-strength MS medium supplemented with 2.0 mg l?1 indole-3-butyric acid and 3% (w/v) sucrose. Rooted plantlets were established in soil. The regenerated plantlets showed no morphological differences from the parent material. This protocol could be useful for germplasm conservation, cultivation, and genetic improvement of S. cordifolia.

Sweet! :) Thanks... so it seems like the cytokines are what matter? As coconut milk contains them and 6-benzylaminopurine is one...
Along with the willow tree, which makes IAA more effective.. it ought to be pretty useful.

Has anyone experience with coconut milk? seems like it could cause some problems. Perhaps it needs filtering, ppt of proteins and sugars, etc?

Oh, and for the auxin, the very common 2,4-D ought to work in place of IBA or IAA I'd think -- but just in more dilute solutions that that is used to kill broad leaf plants.
