Is there a hormone that prevents seeds from sprouting inside a tomato?
453576
Yes, there are. They are called Phytohormones(plant hormones). Some promote seed dormancy. (Cytokinin, Gibberelins, etc,)

According to MochaSofa, as fruit ripens it releases a natural hormone called ethylene. The paper bag traps this gas close to the fruit, thus ripening it more quickly, while still allowing some ventilation. But be careful -- your peaches and pears can go from rock hard to mush in a few days if you don't monitor them. \n\nTo get a little more technical, ethylene triggers the creation of enzymes, which cause starches and acids to break down into sugar. They also break down cell walls, softening the fruit. Fruits ripen in order to kick-start a new growing cycle, by providing their seeds with nutrients. \n\nCertain fruits, apples in particular, produce a great deal of ethylene, so it's important to store them separately from vegetables such as broccoli, cabbage, cauliflower, and leafy greens, as these plants can be harmed by the gas. However, you can add an apple to a bag of plums, tomatoes (yes, tomatoes are a fruit), or other fruit to speed up the ripening process.

if you are in midetereanian country so tomato grow in summer meaning march to april planting seedlings in permenant groud it took arround 40 to 50 days to start fruiting.if you plant it later than this the plant go to flowering while it is still small the longer day light is the more encouraging the flowering ,small flowering plants do give only small worthless fruits.\nyou still can plant the seedlings earlier under the onditions of plastic houses or plastic cover which protect plants from cold weather,\nsome now are planting in green houses tomato which might climb and get big plants

Yes; flowers have ovaries that turn into fruits. The thing is that the flowers are arranged in a series of arcs (that turn into the hands of bananas) that are hidden underneath layers of those large purplish leaf-like things (bracts). The young fruits are revealed successively as the bracts fall off. As the fruits set, they would normally ripen successively, not all at once. That is why banana growers will bag the whole bunch so that ethylene produced from the skin of the ripening bananas at the bottom of it will stimulate ripening of those higher up.\n\nOf course, bananas grown for eating don't have seeds. This is because they are hybrids with one and a half times the usual number of chromosomes. This makes it impossible for the banana to ever set seed. Wild bananas, on the other hand can be chock full of large, round, hard seeds (which can make them unsuitable for eating).

Nope, just like tomato seeds and banana seeds don't. The reason is,they pass through your system and the feces provide an ideal growing environment for a seedling.

I don't know of any.  I do know that poppy seeds will show up, but you have to eat a ton.

Over three years ago my partner was diagnosed with non-Hodgkin’s lymphoma (a kind of leukemia of the lymphatic system) after unknown fevers lasting ten years.  She was given a poor prognosis.\n\nWe included Apricot kernels (and other nitriloside sources) as part of a natural approach to controlling this ‘medically incurable’ disease.  We took a three fold approach, reducing stress on the immune system, removed environmental toxic agents and maintaining a diet containing all ninety+ essential nutrients.\n\nWe included a source of B17.  This B17 nitriloside substance is found in many foods other than apricot seeds.  Most of these foods are uncommon in western diets.\n\nThree years on my partner has not objective evidence of the disease.\n\nI also consumed apricot seeds and increased my essential nutrients.  I had keretotic lesions drop off the backs of my hands and no new ones have returned.  Before this I was having these keretosis removed on a a regular basis.\n\nFoods containing Nitriolside B17…\n\nFruits                                Range*\nblackberry, domesticlow\nblackberry, wild                high\nboysenberry                med.\nchoke cherry                high\nwild crabapple                high\nmarket cranberry                low\nSwedish (lignon) cranberryhigh\ncurrant                                med.\nelderberry                med. to high\ngooseberry                med.\nhuckleberry                med.\nloganberry                med.\nmulberry                                med.\nquince                                med.\nraspberry                                med.\n \nSeeds                                Range*\napple seeds                high\napricot seed                high\nbuckwheat                med.\ncherry seed                high\nflax                                med.\nmillet                                med.\nnectarine seed                high\npeach seed                high\npear seeds                high\nplum seed                high\nprune seed                high\nsquash seeds                med.\n \nBeans                                Range*\nblack                                low\nblack-eyed peas                low\nfava                                high\ngarbanzo                                low to med.\ngreen pea                low\nkidney                                low to med.\nlentils                                med.\nlima, U.S.                                low\nlima, Burma                med.\nmung                                med. to high\nshell                                low\n \nNuts (all raw)                Range*\nbitter almond                high\ncashew                                low\nmacadamia                med. to high\n \nSprouts                                Range*\nalfalfa                                med.\nbamboo                                high\nfava                                med.\ngarbanzo                                med.\nmung                                med.\n \nLeaves                                Range*\nalfalfa                                high\nbeet tops                                low\neucalyptus                high\nspinach                                low\nwater cress                low\n \nTubers                                Range*\ncassava                                high\nsweetpotato                low\nyams                                low\n \nRange*       1000 mg ( milligrams ) = 1 gram \nHigh — above 500 mg nitriloside per 100 grams of food. \nMedium — above 100 mg nitriloside per 100 grams of food. \nLow — below 100 mg nitriloside \n\nNatural sources of Nitriloside contain co-factors that can be more effective than the isolated form.\n\nI hope this helps to answer you question...

Try and find out if you are allergic to oxalic acid derivatives. In my opinion Tomatoes contain plenty of this. However your product may be aprayed with insectide to which you are allergic. Place the tomatoes in a bowl of purified water for an hour to leach out any chemical residues. Try sourcing these from another grocer or possibly grow them yourself in your vegetable patch using natural manure without fertilizers.

its a wonder\n\n!\n\nto know it\nThe seeds are carried away from the mother plant by animals called dispersers. In some cases the animal carries away an entire fruit, in other cases the animal is carrying seeds alone. The animal usually feeds on the fruit (ovary wall), but "tosses" the seeds (or passes them through its digestive system). This assures that seeds end up far away from the "mother" plant, where they can develop without competition from "mom."\n\nHaving been taken away from the parent, it is time for the seeds to sprout or germinate. Seed germination is defined as the emergence of the radicle through the seed coat. Common garden seeds germinate if given just water and reasonably warm temperatures.\n\nWild species usually have some kind of deeper dormancy to avoid sprouting in late summer or fall when the seeds are commonly dispersed. This assures that tender seedlings are not frozen at a young age by the approaching winter. Instead the seedlings do not appear until warm weather arrives in springtime.\n\nIf a species has evolved a very thick seed coat, it may require scarification of that seed coat before water can enter the seed and initiate germination. Perhaps the coat has to be gnawed at by animals, or frozen and thawed repeatedly to crack the coat, or rund down the rocks in a stream bed or up beach in pounding surf to wear the coat down. Perhaps the seed is swallowed whole by the disperser. The thick seed coat protects the dormant embryo as it passes through the animal's digestive system. The weakening of the seed coat through digestion means that the seed is ready to sprout when it gets deposited (along with a bit of fertilizer) by the disperser somewhere new in the environment. Yet other seeds require a brief exposure to fire to scarify the seed coat.\n\nIn species with thin seed coats, light may be able to penetrate into the dormant embryo. The embryo may then either use the presence of light or the absence of light to trigger its germination process. Small seeds with thin seed coats are likely to use light as a signal for germination. If these are buried shallowly enough for light to hit the seed, then its germination will initiate and before it runs out of reserves, its cotyledons will be doing photosynthesis. If the small seed is deeply buried it does not germinate; it has no idea how deep it is buried and may not have sufficient reserves on board to make it to the surface before they run out. Evolution favors shutting down germination in the dark for those species. For large-seeded species, the opposite may be true. There is an advantage to having your reserves buried before starting to germinate...otherwise the sprout just acts as a flag to say..."come and eat my nutritious seeds here on the surface." Evolution favors a large seed with lots of investment in storage to wait until it is buried before sending up its shoot. Such a seed will key in on darkness rather than light. In laboratory you will see an example of each of these kinds of evolutionary adaptations!\n\nIn yet other species, the embryo is fully developed when the seeds are dispersed. They need to be deposited in soil that possesses fungi that serve as host to the seed and seedling until the development is completed and the seedling is big enough to grow on its own. Trying to sprout many orchid seeds in common garden soil is futile...the required fungal hosts are not present...so leaving wild orchids where they naturally grow is the best idea.\n\nIn most species of wild plants the mother invests the seed with abscisic acid. This hormone makes the embryo dormant until environmental conditions and native enzymes permit the abscisic acid to be broken down inside the embryo. The enzyme required is present in the embryo in the fall, but it is inactive until activated by low temperature. About four weeks at 4°C is required to activate the enzyme and degrade all the abscisic acid in the embryo. This cold

A fruit has seeds on it somewhere (a strawberry has them on the surface for example), a vegetable doesnt. Which is why a tomato is acutally a fruit.

Nope. The seeds simply develop on the flower spike.

banana does not grow from seeds.  Asexual reproduction.  Male is useless.  Plants will multiply from roots.

The seed is first planted. You will see little sprouts in one to two weeks. The plant will grow and start to flower. This flower will soon develop the tomato. Tomatoes are also classified as a fruit because they have seeds.\n\nLL.

Botana curus produces Curol, a compound used for treating certain kinds of cancer.  Curol can not be produced in the laboratory.\n  Botana curus grows very slowly and is on the endangered species list, so its ability to provide curol in large quantities is limited\n  I do not quite remember where they grow( i learned that briefly in college, but if it is a terrestrial plant ( grows on land ) I would think that any of the other things that endanger other plants would endanger this one. Lets say, burning of forests to open area for farms. Introducing cows and other herbivorous (plant eating) in fields where the plants grow. If it is a strictly cold weather plant, may be the greenhouse effect (you know with the heating of the planet and so on. e-mail me with the exact environment where they grow and I will give do your homework! good luck

Once again you asked a question that makes no sense whatsoever.  There's no such thing as "gibberline" but there is a plant growth product called gibberellin.  You can't mean THAT, can you?  Why would anyone combine white blood cells with plant food???
