Pineapples are bred two different ways; seeds and vegetative. Vegetative is used more than seeds because seeds germinate slow and are used more in breeding programs. Pineapples are propagated by vegetation (The Biology). The most common parts of the pineapple used in vegetative propagation are the crowns, slips, and ratoons (GeoChemBio.com). The main pollinator for pineapples is hummingbirds.
Heaps of waste are lodging places for the breeding of insects. I do not think a compost pile will do the harm, but unkempt, uncared-for spots seem to invite trouble. There are certain helps to keeping pests down. The constant stirring up of the soil by earthworms is an aid in keeping the soil open to air and water. Many of our common birds feed upon insects.
Moreover, some types of flowers contain a scent to attract insects. A lot of these scents are also attractive to humans, however not all are attractive as some flowers attract flying insects with a foul smell of rotten meat. We should know that colours cannot be seen in the dark as they do not glow (some flowers have pollen grain that glow in ultraviolet light), so scent is important in the dark to
The Flypaper trap plants have a sticky mucus on its leaves. It usually has an attractant, because they can’t catch insects if the insects don’t sit on their leaf. After the insects sit on the leaf, they can’t run away from it, because the sticky mucus on the leaf make insects stick to the leaf. After the insects get caught and died, the flypaper trap plants will start to absorb the insects. The snap trap plants have 2 fast leaves.
The petioles of the leaf have nectars which the ants feed on and also the leaflets produce protein that the ants consume. In return the ants attack herbivores and they chew through the plants that surround the plant thus preventing those plants from shading the Acacia and also inhibiting its growth. These ants are known for removing caterpillars that maybe on the plant and also chewing down plants and vines that maybe at the base of the plant. The other species of Acacia plant that is not coevolved with the ants have no food materials in the leaflets and have hallow thorns. It is clear to see that the plants have coevolved with the ants to as a protection mechanism against other plants and also herbivores.
Avocado is a very popular fruit around the world. The plants from avocado (Persea americana, Miller) are native from Central/North America (Mexico) from where it spread to various regions. Their ripe fruits are consumed on a large scale in the world and have healthy properties. Some studies have shown that a diet enriched with avocado fruit lowers total cholesterol and low-density lipoproteins levels without changing high-density lipoprotein levels [1-5]. The seeds from avocado constitute a high percent in this fruits (13-25%) depending of varieties, which commonly are discarded as industrial waste .
If the plant is infected, their leaves may lose as well as the size and quality of the fruit ay reduce. It can be particularly severe on muskmelon but also affects squash, cucumbers and watermelon. Infection is most likely to occur on vine crops weakened by poor growing conditions or aging. Symptoms first appear in the middle of the season on the leaves nearest to the centre of the plant and infected fruit have circular, sunken, brown spots that develop into a dark olive-green or black powdery mat. To help prevent this disease, proper soil fertility and moisture should be maintained throughout the season.
Factors such as fungal diseases, physiological disorders, mechanical damage or a combination of these are the leading causes of post-harvest losses. Major cause of postharvest losses in papaya is anthracnose disease caused by Colletotrichum gloeosporoides (Paull et al., 1997). After harvest place the fruit into single layer, light colored crates preferably containing a foam layer for cushioning. Mesh bags, baskets etc are unacceptable for papaya transport due to more chance of bruising. Care should taken during the transport in field crates to minimize the movement of fruit (
This fat protects human’s internal body organs from injuries. However, this fat can be dangerous if the amount expands drastically in your body. The tendency of storage fat to increase depends on what you consume. The most normal amount of fat for men normally have storage fat of 8 percent-19 percent in their bodies, the normal percentage of storage fat for women is 21 percent -35 percent. Now, here are some foods that burn fat and make you feel happy while eating it: • Apples (the green ones) We know the health benefit of this fruit.
They have evolved through the years and have adapted to pollination syndromes in order to ensure successful fertilization by attracting pollinators that have the ability to pollinate them. Their pollinating agents are mostly vertebrates such as mammals, birds, reptiles, amphibians, and fish. Insects can also be pollinating agents, with bees being one of the most economically beneficial agents. Every pollinator has its own unique morphological, behavioral and floral preferences, this result in each one having different directions on floral phenotype. When a flower has evolved be pollinated by different pollinators (polyphilic flowers), less effective pollinators can waste pollen which would be distributed better by the main pollinator.
