How to induce flowering in cacti, hormones, gibberellic acid, photoperiodism, plant biostimulants etc
Dreamwalker. posted a topic in Cacti & Succulents
This post began as below.............but has become a general investigation into how to induce flowering in (immature or hard to flower) cacti.................mostly though hormone use..............feel free to add your imput................... Has anyone had experience inducing flowering with gibberellic acid...?....seems a good way to promote fruiting in slow to mature or reluctant cacti.

I came across this on hostilis wanted add...................(I hope you don't mind me picking up on it).....................it seems most days I come here, I see something that's entirely new to me.................and this is fascinating..................probably a familiar item in a lot of older members collections...................I'd be interested to know how common it is..................(said to be rare).........and keen to see any pic's, or discussion of it.....................

K post seed giveaway....Cereus peruvianus x Trichocereus pachanoi
Dreamwalker. posted a topic in Seed & Plant Swaps
...1000th post seed giveaway... I'm not sure if anyone will be interested in this seed. Cereus peruvianus x Trichocereus pachanoi (Trichocereus pachanoi mother... I'm 99% sure, the pach had 1 open flw and the cereus pollen was collected 2 days earlier, I'm rural, no cacti for miles & miles, besides in was in the conservatory). Possibly the cereus pollen induced the trich to self pollinate?? only growing them will establish if they are a x or a good T pachanoi not the PC form. A propagator or heatpad would be needed for germination in temperate climates. Why x them? it was the only pollen I had. What's it good for? novelty....maybe a cold hardy cactus, thats sweet fruiting like the cereus fruit, (trich fruit is bland, but good with liquid honey). So anyone in nz just pm (unlimited supply for nz ) (Haven't had 1 nz member yet) For OZ & beyond I have only 5 lots (at this time) these are only available to anyone who has sent me seed in the past.....STILL HAVE 3 lots LEFT.......... If you have any kind of cacti seed to trade...harrisa...trich...selenicereus...Acanthocereus.. .stenocereus...anything just pm (unlimited supply for real trades) -
Simple method for Rapid intra/interspecific hybridisation via chromosomal polyploidy
Dreamwalker. posted a topic in Cacti & Succulents
"plantlets generated from the graft junction contained the genetic information of both species." http://phys.org/news/2014-06-species-sex.html Note; has been edited a few times. hopefully improving the accuracy, feel free to comment and/or improve it further. Crude summary of Method A loph x trich interspecific hybrid is used as an example. 1) graft loph onto a trich, wait a few months, or take a biopsy from the union/joint of a mature craft. 2) carefully remove a few plant cells from the junction of the graft. 3) use tissue culture tec. to grow these cells into plantlets. 4) a % of these planlets will contain chromosomes from both the trich and the loph, Polyploidy. 5) these plantlets will not be a trich or a loph, you have created and new and unique species, a triloph. 6) each triloph will be unique, dependent on the expression profile of the genes it combines. This simple tec has been accessible to you all along, since the first gardener 1000 of years ago figured out how to graft. Of course its only been in the last 100 years that we figured out tissue culture tec, And only since the researcher in the last few months experimented with the cells from the graft union and realised that chromesome transfer occurs in this limited area, not the scion, not the rootstock, but the thin veil of cells of the boundary union between the 2. If you can graft 2 plants together, you can in theory create such hybrids. Additionally the hybrid plantlets can be grafted thereby combining the genomes of additional species. The 2 main advantages are instant hybridisation, (months rather than years), and the (multi) hybridising of distantly related plants. -

The science behind many antidepressants appears to be backwards, researchers say
Dreamwalker. replied to Dreamwalker.'s topic in Pharmacology, Chemistry & Medicine
Just going with a feeling here...there are diseases or rather symptoms, in this case depression that may be due to various causes, Stress likely promotes neural inflammation, an illness that causes neural inflammation may express symptoms such as depression. Treating the inflammation or cause of (virus etc) might help in the latter but perhaps not for stress induce depression. Actually just thinking about it , inflammation is a symptom. so treating it might relieve depression but not cure it. The cure would require understanding the origin/reason for the inflammation ie stress, virus or whatever. A bit beyond a 3 minute gp visit. Seems to be the theme of our age, not to address the root cause, but circumnavigate for a quick fix, like cutting the top of the weeds & leaving the roots. -

Good things come to those who wait? More serotonin, more patience Anti-depressant use soars in England, linked to recession Saffron packs a punch for mental illness "saffron has shown to be a safer alternative to pharmaceutical antidepressants" -
looks like its joined in the middle, shame about the outer skin shrinking, if its a success will have an interesting scar. The bubble wrap blinds are a good idea.

I'm not sure if I can really help, I tend to be a real sceptic where big money is concerned, Big pham is like oil corp & all the others - all about profit, A CEO would soon be ejected or a corp. soon disposed if profit wasn't 1st & foremost. Hence billions spent by these interest lobbying Govt, (mostly usa, as they dictate to the rest of us) = a messed up world. Its kinda sad when peeps buy into status quo, there is always so much manipulation going on to serve some agenda, that's generally not in your interest. Quick fix pills for example. Personally I agree with you re stress. So maybe its the stress that should be addressed, if possible remove stress from the life of the depressed person. Stress can be all kinds of things...self stress from self disappointment, Stress from over commitment, like family & work obligations. Stress from a weaken physical body due to health or natural ageing. The problem is we can have a hard time escaping from stress. Like from work, we are obliged to work 40+ hours per week, but maybe we can only handle 14 hr's, not much opportunity there, who's paying all the debts etc?So the pop is drugged up with anti-depressants...that generally will get you back to work for better or worse. So sometimes perhaps more often than not there is no real cure for depression, because your life's environment entraps you in a stress cycle. Therefore accept your disability & manage the stress, not always easy. I feel there are those who get depressed & then there are those in denial. I think the best treatment may be to stop what ever your doing...take some time out & self indulge. Of course if its because your lover just left you, thats another story. -
So a lot of my grafts are getting big,...wondering Where is the best place to cut a graft; through the union? a few areoles above the union, so remaining scion can bud? ???? When..... what season? How large can it get....can you leave it on the root stock forever?

Wish people would stop spouting pseudo bullshit
Dreamwalker. replied to ace1928's topic in Chill Space
as I say "I don't really hold a view either way, & make no recommendations, as I wrote its a tough call" You are on the other hand apparently well informed ....at the risk of being pulled into a discussion, (chomped up & spat out) of which I know very little..... there does seem to be an association between inflammation & autism, & other perceived neuropsychiatric diseases,,,,seemingly from conception (mothers environment) to death. So do you consider that there has been no historical increase in the rate of perceived neuropsychiatric diseases, such as autism? What I find of concern is an increasing trend towards the idea & implementation of compulsory vaccination. At a glance it seems like a great idea ...remove pathogenic virus's bacterium etc from the population. But that seems to me to be a Pandora's box, due to the sheer complexity of body & cellular function. Many of these factors drive evolution.....It feels like comparing permacultural with monoculture. How vaccines change the way we think about disease Anti-vaccine mothers discuss their thinking amid backlash -

LOL vaccinations and autism http://www.tandfonline.com/doi/abs/10.1080/15287394.2011.573736 as per request..10 sec search..I get your a mother, but that doesn't excuse rudeness. I'm constantly reading research news relating to autism, mainly because there is considerable research funds available for its research, Unquestionably it can be linked to all kinds of environmental influences. Which is probably why vaccines can tip the scales. We are not clones & so all bodies have variance/thresholds to environmental influences, & our bodies react accordingly. You could use http://scholar.google.co.nz/scholar you will find research both in support of your view & research proving the opposite..............makes you wonder........... I don't really hold a view either way, & make know recommendations, as I wrote its a tough call....nor am I here to judge your parenting. Though your fascist breeding beliefs are offensive. I was just adding my experiences to the discussion. Your not 1 of those meat clever types are you? http://www.webmd.com/brain/autism/searching-for-answers/vaccines-autism discusses it..pros cons...but in lay terms and a tendency towards your beliefs........... -

question - best time to cut off graft & where?
Dreamwalker. replied to Dreamwalker.'s topic in Cacti & Succulents
I'm still new to grafting....very addictive.... I was hoping there would be a lot of opinions about when/where to cut. I've read slicing the top off button grafts, causes massive pupping. But found nothing re columns. Anyhow came home this morning to see my J3 open pollen (~410mm high, 10 months old, seedlings are 50 - 100mm high) had fallen, odd its inside...no wind....luckily no damage.....just gotta get the nerve to slice a column scion above a few areoles, & see if the remaining scion pups. while I'm here.....Yowie x super pedro (thanks to a nomadic member for these awesome seedlings) To cut or not to cut.th....... Today counted 5 areoles on the remaining scion........... -
Just a bit off topic...but the geometrizans you grew from seed.....I've grown a few as well, & wondering how many years they take before they flower?
