Grafting? and other plant realted questions

Post by DriParker » Mon Jun 20, 2005 4:53 pm

Hey y'all, i need some help. I know a little about these topics, but not enuff to answer the questions. The ones i need the most help on are about grafting. thanks for any help y'all can give! ~Dri Parker~

(1) When you make a graft on a tree, why is it essential for you to be sure that the cambium layer of the stock and that of the scion are in contact with each other?

(2) What kind of graft would you use to save a fruit tree that has been completely girdled by a rabbit gnawing off a ring of bark?

(3) What does hoeing the garden (or running a cultivator on a farm) do besides tearing out the weeds?

(4) Would you cultivate more or less frequently than usual during very dry weather?

(5) In the spring of the year maple trees are tapped for sap to make sugar. Why are they tapped in the spring rather than in the fall?

(6) When you tap maple trees, should you cut through the bark and into the wood, or just partly through the bark? Why?

(7) When you transplant flowers in the garden, why should you take the roots up with a ball of earth about them-rather than loosen the soil and pull the roots out?

( 8 ) Why is it occasionally a good thing for you to wash the leaves of your house plants?

(9) What advantage is there in keeping water plants in a fish aquarium?

(10) The cod and other fish caught on the Banks of Newfoundland are heavier (and the total catch is heavier) during sunny seasons than cloudy seasons. How do you account for this?

(11) Potato beetles do not eat the tubers of the plant which man uses; they feed only on the leaves. Why take the trouble to poison the beetles then?

(12) Why does the florist sprinkle water on the walls and walks in his greenhouse as well as on the soil and growing plants?

(13) Sweet corn can hardly be planted in Canada until mid-May because of late frosts. Yet it is ready to eat in three months' time. How is this possible when in southern Illinois sweet corn matures very little earlier although it is planted the first of April?
Please don't hate me 'cause i don't like biology! ^_^

7) the small haires on the roots can be injured when crudely separated from the surrounding earth, and they are needed in efficient sucking up of water and nutrients
8)if the leaves get to dusty the sunlight can be obstructed by dust and sorts
9) in an aquarium you can control the environmental conditions (rather than in a regular bowl with water in it.. and another plus, you generally need water for waterplants, and an aquarium is an ideal object for containing water)
10) more sun-> more photosynthesis -> more plants/ autotrophes -> more things that eat the plantish thingies -> more thingies to eat for the fish -> heavier fish
11) leaves are needed to sustain the plant.. without it even the actual potatoes die
13) probably different species/breed or something.. and lots of different environmental factors

1)When grafting, it is extremely important that you bond the cambium layer of the rootstock with the cambium layer of the scion. Matching up these two surfaces as closely as possible is extremely important. These two sections of cambium layer are going to bond and will be the only thing holding the plant together. This bond is almost like a natural form of welding. The cambium layer will also dry out if not matched up properly.
2)Bridge Graft is used to save trees when the that has been completely girdled by a rabbit gnawing off a ring of bark.
3)For good growth, the plant must have space in the soil to get air; room to grow roots; suitable soil acidity or alkalinity; and adequate water, sunlight, and mineral nutrients. Air space, root room, and water available to a plant depend largely on the soil structure. This, in turn, is closely related to the organic matter in the soil and a suitable distribution of mineral particles of different sizes to keep the soil open and porous, permit excess water to drain away, and air to enter.

Another way to solve the rabbit problem is a process called in-arching. You basically plant small rooted cuttings or seedlings around the perimeter of the tree and graft them to the host tree. The cut on the host should look like a "T". As mentioned previosly, bridge grafting is another solution. However, inarching has long term benefits. It's also a good way to change rootstocks when new advances are made for that particular tree.

1. When making a graft on a tree, it is extremely important that the cambium layer and the scion layer are matched up as closely as possible. These two surfaces if not matched up properly will allow the cambium layer to dry out. They need to form a bond which is like a natural weld.
2. I would use a bridge graft. The bridge graft is used to usually at the base of a tree, it provides support and it provides as a pipline that will allow water and nutrients to move across the damaged area.
3. When the soil gets loosened it allows oxygen to go into the soil, plants need oxygen and space to grow roots. Loose soil allows mineral particles, water, sunlight and nutrients to the roots of plants and trees.
4. I would cultivate less because when there is dry weather the soil will store water and other nutrients. If you coltivate more then the soil will become so dry that most or posibly all of you plants would die.
5. Because in the spring it is cold and that is when the sap is coming from the roots to the leaves. In the fall it is warm and the sap is in the roots already and you can tell that the sap is in the roots because the leaves are brown and red and orange instead of green.
6. You should tap through the bark and into the wood because the tree is like a vien, there is'nt any sap in the bark of the tree. When you tap into a tree it is like drawing blood from an arm of a human.
7. Because you want the root hairs of the flower not to be damaged. The root hairs are what keeps the plant alive, they suck up water and nutrients from the soild and if they are damaged then the plant will probably die.
8. Because a plant breaths through its leaves and if there is to much dust on the leaves it can't breath. Also it prevents sunlight from getting to the leaves of the plant.
9. In an aquarium you can control the environmental conditions, if you just have a plant in a bowl or somthing you can't control the environmental conditions. Generally you need water or waterplants and an aquarium is the perfect object for containing water.
10. The more sun there is the more photosynthesis there is. The more photosynthesis the more plants, if there are more plants then the fish can eat more food and become biger and heavier.
11. Because if the leaves are eaten from a plant then it killes the plant. Patato beetles distroy plants and I know this from first hand expierience. If you don't kill the potato beetles then they will kill you plants and you won't have a very good harvest.
12. Usually a greenhouse is made out of glass or a see through material. If you sprinkle water on the walls and walks of the greenhouse it causes humidity which helps the plants to grow better and faster.
13. I would have to say it has somthing to do with the weather and the corn. Canada has different weather then southern Illinois and they probably use a different kind of corn. One place might be more humid then the other which would make a big difference in growth

#3. Aerates the soil and loosens it.
Hope This Helps at least a lil bit :D
