Tomatoes are a perennial,originally from the tropics, so if temperatures never get below about 40F they could conceivably be kept year round, pruned, treated etc. Also, if you are in an area with a long enough season, you can direct seedtomatoes to be transplanted for a fall crop.
Seedlings should usually be transplanted after the last frost date foryour area. Contact your local agricultural extension office if youdon't know what that date is. Some general ranges are: zone 9 Februaryto early March, zone 8 March to early April, zone 7 late march to mid April,zone 6 mid to late April, zone 5 mid May. These are not absolutesand there will be years when tomatoes could be planted earlier and otheryears when cold temperatures will last longer than normal.
This can be a sign of inadequate nutrients in the potting mix, too lowtemperatures, or improper light level. Make sure the temps rangefrom 60 to 75 degrees Fahrenheit and that the lights are on at least 14to 16 hours per day. Once that requirement has been met, considerfeeding them with manure tea or a fertilizer concentrate. Miraclegrow 15-30-15 can be used at a rate of 1 level teaspoon in a gallon ofwater to water about 150 seedlings. This is a low enough concentrationto avoid burning the roots. Some other fertilizers contain micronutrientswhich can be very beneficial for tomatoes.
It depends mostly on the temperature, humidity, and the age of the seed. Below 65 degrees, germination is seriously delayed and at 50 degrees virtuallystops. Older seed also tend to take longer to germinate than freshseed. Generally, good seed will germinate within 4 to 7 days andolder seed within 20 days. There are a very few varieties that takeup to a month to germinate and thats just the way they are. Thereis one species closely related to tomato that normally has to go througha tortoises gut before it will germinate!
You could try to 'prick out' the smaller seedlings and transplant themto other jiffy pots or into small pots as individual plants. Do thiswith a knife or a fork with only one or two tines. This method isespecially good if you have limited numbers of germinated plants for agiven variety and can't afford to waste plants.
Moisten a paper towel, wring it out, then spread it open. Placeseed on the towel and roll it up very loosely. Place the towel ina ziploc type bag and place in a warm spot such as on top of the refrigeratorfor 2 or 3 days. Check for germination. Some people use thismethod to get germinated seed to plant. This allows them to have100% seedling emergence in the growing media. It works but handlingthe damp seed is time consuming.
Hypothesis:Photosynthesis is a process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose....
During the process of photosynthesis, carbon dioxide plus water in the presence of sunlight, enzymes and chlorophyll produce glucose and oxygen as waste product.
Plant researchers have developed an online application that predicts how crop growth is affected by photosynthetic changes at the molecular, cellular or leaf level of plants.
The first European Congress for Photosynthesis Research (ePS-1) will cover all aspects of photosynthesis, from genetics and molecular mechanisms, to crop yields, artificial photosynthesis and solar fuels and a ePS-Young meeting for PhD students and postdocs has been organized for the weekend before the event.
An el cheapo heating pad from Wal-Mart works just as well as an outrageouslyexpensive seedling heating mat. Use a probe type thermometer (availableat Wal-Mart for under $20) to check the temperature and cover it with a piece of plastic to keep from accidentally getting it wet.. Anothergood heating pad is a waterbed heater. If you are really growinga LOT of seedlings, consider using an electric blanket. Spread itover a large table, cover with a plastic sheet, sit trays on top, and adjustthe temperature to about 72 degrees fahrenheit.
This process is what translational photosynthesis is all about – taking scientific discoveries from the lab and translating them to useful outcomes in the field.
Through reading various books and web pages it was made clear that carbon dioxide is definitely one of the raw materials needed for photosynthesis, but I wanted to see whether this is actually true and if carbon dioxide is taken away completely will the plant photosynthesize at all.
This is happening more and more often these days. Seed are beingsubstituted for the real variety or crossed seed are being shipped. It helps if you know someone else who has grown them and can find out ifthe tomato is worth growing. There is a potato leaf faux Red Brandywineand a yellow that is being called Lillian’s but is not. The potatoleaf Red Brandywine is reported to be an excellent tomato and at leastone good report is on the net about the faux Lillian. I personallydon’t want the imposters, I bought seed of a specific variety and if itsnot that variety, then I want the real thing. You might considergiving the seedlings to someone who would like to give them a try.
The occurrence of photosynthesis is very important to us as humans, because it provides us with the oxygen we need to breathe and plants are at the bottom of every food-chain and so without them, I would collapse....
