Frequently Asked Questions
1. What is the difference between a fruit and a vegetable?
A vegetable is the edible part of a establish. Vegetables are normally grouped according to the parcel of the plant that is eat such as leaves ( lettuce ), stem ( celery ), roots ( carrot ), tubers ( potato ), bulbs ( onion ) and flowers ( broccoli ) .
A fruit is the fledged ovary of a plant. So a tomato is botanically a yield but is normally considered a vegetable. According to this definition squash, pepper and eggplants are besides fruits. then there are seeds such as peas which are besides considered vegetables .
The Funk & Wagnalls Multimedia Encyclopedia has the pursuit definitions :
vegetable, the comestible product of a herbaceous plant-that is, a plant with a soft stem, as distinguished from the edible nuts and fruits produced by plants with woody stems such as shrubs and trees. Vegetables can be grouped according to the comestible contribution of each plant : leaves ( boodle ), stalks ( celery ), roots ( carrot ), tubers ( potato ), bulbs ( onion ), and flowers ( broccoli ). In accession, fruits such as the tomato and seeds such as the pea are normally considered vegetables.
Fruit, fledged ovary in flowering plants, together with all inseparably connected parts of the flower. In hard-and-fast botanical custom, the mean may be restricted to the ovary alone. normally the term fruit is much restricted to succulent, comestible fruits of woody plants, to melons, and to such little fruits as strawberries and blueberries. In nature, fruit is normally produced only after fertilization of ovules has taken place, but in many plants, largely civilized varieties such as seedless citrus fruits, bananas, and cucumbers, yield matures without fertilization, a process known as parthenocarpy. In either event, the festering of the ovary results in the shrivel of stigma and anthers and enlargement of the ovary or ovaries. Ovules within fertilize ovaries develop to produce seeds. In unfertilized varieties, seeds fail to develop, and the ovules remain their original size. The major service performed by fruit is the auspices of developing seeds. In many plants, fruit besides aids in semen distribution .
2. How can you tell when a watermelon is ripe?
From the publication “ Watermelon Production in California “ : The criteria for picking watermelons include color variety ( the most authentic ), flower end conditions, and rind pitting. Watermelons do not separate from the vine when ripe ; a crisp tongue is used to cut melons from the vines. Melons pulled from the vine may crack exposed .
From “ Home garden watermelons “ : To test melons for ripen, rap the side of the yield with your knuckles. A faint or metallic sound means that the fruit is still green ; a dull fathom means it is good. This is most dependable in the early on good morning. During the heat of the day or after melons have been picked for some time, they all sound ripe. Fruits have a “ ground spot ” where they rest on the labor ; this spot turns slightly yellow as the fruit matures. Watermelons tend to become harsh as they mature. The tendril cheeseparing to the yield darken and dry up as the fruit ripens. Do not pull melons off the vine ; use a sharp knife for cutting .
3. The leaves of my tomato plants are curled, the stems have bumps and the lower leaves turn yellow and fall off. Is something wrong?
This describes a convention tomato establish. It is natural for the leaves of tomato plants to curl under. The bumps on the stalk are normal and many tomatoes have them. They are actually nodes and if the stalk were placed in a glass of water roots would grow out of the nodes. The lower leaves of the tomato plant normally turn yellow and fall off as the plant grows up.

4. The fruit on my zucchini plant do not grow but instead shrivel up and fall off. What is wrong?
Squash, cucumber and melons require insects, normally honeybees, to pollinate the flowers. When no insects are available, the fruit is not pollinated and so it shrivels up and falls off the implant. When no bees are present in the garden or the bee
population is excessively depleted for good fruit set, the give gardener can substitute for the bee by pollinating by bridge player. Hand pollination is a boring job, but it is the lone means of obtaining fruit set in the absence of bees .
The pollen is chicken in color and produced on the structure in the center of the male flower. You can use a little artist ‘s paintbrush to transfer pollen, or you can break off a male flower, remove its petals to expose the pollen-bearing structure, and roll the pollen onto the mark in the center field of the female bloom. When hand pollinate, it is important to use merely newly opened flowers. Flowers open early in the dawn and are receptive for entirely one day .
The female bloom in cucurbits can be recognized easily by the bearing of a miniature fruit ( ovary ) at the base of the flower. Female squash flowers are much larger than the female flowers on melon and cucumber plants. The male squash flower can be identified by its long, slender bow. The female squash flower is borne on a identical short-change stalk .
In melons and cucumbers, male flowers have very short stems and are borne in clusters of three to five, while the females are have a bun in the oven individually on reasonably longer stems.
