I just did a search on 'rooting hormone' and found 51 hits in the forum about this topic, so you'll find more info there that I can give you. In short, some have tried it with success. It has never worked for me, where as Superthrive has done wonders for improved orchid roots for me. But it depends upon what orchids you're trying to propagate, too. Orchids aren't like a lot of other plants in that way. If you took a 10 pb plant, and divided it into 10 individual pbs, you might get 10 plants out of it, but it will be a number of years before you got anything to bloom. Orchids use the older pbs as food to support new growth. I'm also trying to say that orchids just don't propagate like shrub cuttings- in general you can't just cut off pieces and expect that each will readily grow a new plant. Some types lend themselves more to this, but again not recommended.

Hello Jon. Yes it was my understanding that Chris used a systemic spray. It does sound like it is possible to parthenocarpic induce fruit set in sterile fruit with out natural pollen. We likely tried something that was available at his nursery like tomato set spray or a sales person from one of his vendors recommended a spray. Here is some information. When I have time I will give this a try? Best http://www.ubcbotanicalgarden.org/forums/showthread.php?p=21254 Tomato Fruit Set Spray User Name Remember Me?

Thanks! Megami View Public Profile Visit Megami's homepage! Find all posts by Megami #2 July 13th, 2005 Unregistered Posts: n/a Re: Tomato Fruit Set Spray -------------------------------------------------------------------------------- The active ingredient is the man-made auxin (hormone) 4-Chlorophenoxyacetic acid (4-CPA) that is well known to promote fruit set commercially. Bio101--Why it works: "...Fertilization within the ovules stimulates the ovary enclosing them to begin growing into a fruit. Within a few days the ovary begins to swell. This is called the fruit set. Fruit development is under the influence of the plant hormones auxin and gibberellin. Pollen is one of the richest natural sources of auxin, so it is thought that the initial stimulus to fruit growth comes simply from the auxin to which the pistil is exposed as a result of pollination. Applying the hormone auxin or gibberellin to the ovaries of flowers can induce a fruit to develop without pollination or fertilization. This is called a parthenocarpic fruit and is, of course, seedless." http://www.crfg.org/tidbits/gibberellic.html Gibberellic Acid for Fruit Set and Seed Germination John M. Riley The following information is taken from a article by John M. Riley that appeared in the 1987 CRFG Journal (vol. 19, pp. 10-12). See the back issue information for price and ordering information. The Germination Process The first stage of germination consists of ingesting water and an awakening or activation of the germ plasma. Protein components of the cells that were formed as the seed developed, became inactive as it matured. After an uptake of water, the system is reactivated and protein synthesis resumes. Enzymes and hormones appear and begin to digest reserve substances in the storage tissues and to translocate the digested substances in the storage tissues to the growing points of the embryo. The sequence of the metabolic pattern than occurs during germination involves the activation of specific enzymes at the proper time and regulation of their activity. Control is exercised by four classes of plant hormones: inhibitors such as abscissic acid which block germination; auxins which control root formation and growth; the gibberellins which regulate protein synthesis and stem elongation; and cytokinins that control organ differentiation. Ethylene is also believed to have a control function in some plants. Sometimes the last three controls are used together to crash through dormancy in germinating difficult seed. Gibberellic Acid Gibberellic acid (actually a group of related substances called gibberellins) was discovered as a metabolic byproduct of the fungus Gibberella fujikuroi, which causes the stems of growing rice to elongate so rapidly the plant collapsed. Synthetic forms of gibberellic acid are available commercially. Gibberellic acid (GA) is a very potent hormone whose natural occurrence in plants controls their development. Since GA regulates growth, applications of very low concentrations can have a profound effect. Timing is critical: too much GA may have an opposite effect from that desired; too little may require the plant to be repeatedly treated to sustain desired levels of GA. Effects of Gibberellic Acid Overcoming dormancy. Treatment with high concentrations of GA is effective in overcoming dormancy and causing rapid germination of seed. Concentrations of about 2 ppm can cause tubers to sprout earlier. Premature flowering. If a plant is sufficiently developed, premature flowering may be induced by direct application of GA to young plants. This action is not sustained and treatment may have to be repeated. Formation of male flowers is generally promoted by concentrations of 10 to 200 ppm., female flowers by concentrations of 200 to 300 ppm. Concentrations of more than 600 ppm markedly suppresses initiation of both male and female flowers. Increased fruit set. When there is difficulty with fruit set because of incomplete pollination, GA may be effectively used to increase fruit set. The resulting fruit maybe partially or entirely seedless. GA has increased the total yield in greenhouse tomato crops both as a result of increased fruit set and more rapid growth of the fruit. Hybridizing. Pollination within self-incompatible clones and between closely related species may some times be forced by the application of GA and cytokinin to the blooms at the time of hand pollination. Increased growth. GA applied near the terminal bud of trees may increase the rate of growth by stimulating more or less constant growth during the season. In a Department of Agriculture experiment, the GA was applied as a 1% paste in a band around the terminal bud of trees. Treatment was repeated three times during the summer. Walnut tee growth was 8.5 ft. for treated trees, 1.5 ft. for untreated trees. Frost protection. Spraying fruit trees at full-blossom or when the blossoms begin to wither can offset the detrimental effects of frost. Root formation. GA inhibits the formation of roots in cuttings. Recipes Although GA is not listed as a "poison", the following precautions should be observed: Flush with water any GA that may get into the eye. Avoid skin contact if possible. If skin contact is suspected, wash with soap and water. Do not re-enter an area after spraying until the GA spray is fully dry. Avoid ingestion of GA. The powder may be dissolved as specified below to give the desired concentration.

There are a couple of different formulas and they all work pretty well, sometimes producing roots on cuttings in a matter of days. And yes, Ken, Rootone has Thiram in it. I prefer to use one with indolebutyl 3, it seems to work faster for me. I've been using it for cuttings for years, but I just recently thought about using it on the hosta pieces! Sandy

I DID have the same tightening pressure in the head when I wake up bit it went away after I cut out my overindulgence in tea and coffee. I still DO wake up around 3 am. sometimes, I am wide-awake, and I AM ON HRT! I have noticed if I keep up with a high level of calcium -- my GYN said 1500 mg of calcium AND 800 IU of Vitamin D is also necessary. Don't forget to get the type of calcium that has magnesium, else you are really not absorbing the calcium into your system! So everything working in concert correctly has helped me get a solid night's rest but if I forget my vitamins, then the HRT has no effect... The other thing I have noticed is if I wake up hungry at the magic hour of 3 a.m... I sometimes have not eaten enough for supper (ergo the cure of those who take tryptophan)... I often skip dinner and graze on smaller items... so had to cut that out... But I am going to try that natural progesterone cream... anyway, Doc says he will only keep me on HRT for a very short period of time, wants me only to take it every other day, but I need to work for a living and I need my sleep. But like I said, it is not working that great anyway... You can try the HRT for a short term just to see it's effect.. I remember taking two pills the first night and it knocked me out and proved that it was a key piece of the puzzle. I went to a sleep seminar not too long ago when it first started happening to me at age 53, and when the speaker asked for a raise of hands for a) who is under stress then b) who can't fall asleep and c) who is menopausal, man, the hands that went up was astounding.. I then realized this is biological and definitely related to the whole hormonal complex..... of course, it pays to stay as calm as possible as pointed out.. perhaps your headache is related to a bit of panic? At the very least if it continues, ask for a blood pressure check... be well
