Plants Crops
Why is it important to maintain the genetic diversity of crop plants?
I know its important to maintain diversity, in case the new GM crops don't have resistance to a new strand of fungi/bacteria etc that would devastate our agricultural crops, thus needing to go back to our traditional crops explaining a need for maintain diversity, but is there any other reason we would need to maintain genetic diversity other than the increase it provides in gene pool thus saving us from potential food loss?
I would really appreciate help, thanks so much for taking the time to read/answer this!
The greater the number of variations of a species the better the chance that the species will survive in the long scheme of things. So if you have a single crop with one phenotype and a new disease arises tomorrow and attacks this one phenotype and kills all of them, it is the end for that species. But if there are lots of variations, many phenotypes, there is a greater chance that one of them would survive the new disease.

Genetically Modified Crops (Hardcover) $129.77 Plant molecular biology came to the fore in the early 1980s and there has been tremendous growth in the subject since then. The study of plant genes and genomes and the development of techniques for the incorporation of novel or modified genes into plants eventually lead to the commercialisation of genetically modified (GM) crops in the mid-1990s. This was seen as the start of a biotechnological revolution in plant breeding. However, plant biotechnology has become one of the hottest debates of the age and, in Europe at least, one of the greatest challenges that plant scientists have ever faced.This book covers the history and development of the science and techniques that underpin plant biotechnology. It describes the GM crops that are or have been grown commercially around the world, including failures as well as successes, and the new varieties that are being developed. The safety record of GM crops is reviewed together with the legislation that has been adopted to cover their use. The book also deals with the concerns of consumers, the GM crop debate and the prospects for the technology. In the second edition, sections on current GM crops and future developments in plant biotechnology have been greatly expanded, while those on techniques, legislation and the GM crop debate have also been updated.The book is a concise, comprehensive and readable study that is accessible to a general readership with a scientific background but also provides useful information for the specialist. |

Plants (Paperback) $20.91 Plants form a fundamental element of the biosphere, and the evolution of plants has directly affected the evolution of animal life and the evolution of the Earth`s climate. Plants have also become essential to humans not only in the form of cereal crops, fruit, and vegetables, but in their many other uses in wood and paper, and in providing medicines. In this Very Short Introduction Timothy Walker, Director of the Botanical Gardens in Oxford, provides a concise account of the nature of plants, their variety and classification, their evolution, and their aesthetic and practical value, stressing the need for their conservation for future generations. |

Neolithic Founder Crops $68.51 High Quality Content by WIKIPEDIA articles The Neolithic founder crops (or primary domesticates) are the eight plant species that were domesticated by early Holocene (PrePottery Neolithic A and PrePottery Neolithic B) farming communities in the Fertile Crescent region of southwest Asia, and which formed the basis of systematic agriculture in the Middle East, North Africa, India, Persia and (later) Europe. They consist of flax, three cereals and four pulses, and are the first known domesticated plants in the world. Although domesticated rye (Secale cereale) occurs in the final EpiPalaeolithic strata at Tell Abu Hureyra (the earliest instance of a domesticated plant species), it was an insignificant in the Neolithic Period of southwest Asia and only became common with the spread of farming into northern Europe several millennia later.

Plants in Agriculture $117.9 Plants in Agriculture fulfills the need for a single text that promotes a comprehensive understanding of how plants operate in agriculture. By setting plant development firmly in the context of the realities of soil, climatic, and biological conditions the authors insure that this book wil be of wide use to crop scientists, horticulturalists, and pure and applied biologists. The strengths of this book are that it synthesizes subject matter from a wide range of perspectives, from sowing to harvesting, storage, marketing, and consumption of crops. Some major aspects, such as the impact of stress on yield and the effects of growing conditions on the nutritional quality of plants are synthesized for the first time. It is also a highly practical work that integrates knowledge from other disciplines, such as soil science, human and animal nutrition, and crop protection. Finally, it chooses from cool temperate, warm temperate, tropical, and arid agriculture to highlight the universal significance of principles. Simple terms and concepts are fully explained for the uninitiated. Author: Forbes, James C./ Watson, R. D./ Forbes Watson Binding Type: Paperback Number of Pages: 372 Publication Date: 1992/08/20 Language: English Dimensions: 9.60 x 7.39 x 0.69 inches |

Hydrophonic Gardening - How Gardeners And Plants Benefit From This Method
The conventional farming helps people plant crops over land, also gives it water in order to help growth then start harvesting as the time comes.
Many such practices made use of herbicides and fertilizers and pesticides , some contaminated sewage and also irradiation.
Technology has thus found yet another way to enhance crop production without harming the welfare of people and also the environment. This is done by doing hydroponics farming.
Since plants need the water in order to survive but however it's only one ingredient. Other and most vital are nutrients. Many scientists have found that it's only all this is diffused into several water systems then roots of the plants consume it hence it grows.
Doing all this in a very controlled environment like a greenhouse for example, the nutrients are to be mixed into all the water systems hence allowing the plant to produce more yields and this is mainly what hydroponics gardening deals about.
In order to show how effective it actually is, many scientists did a comparative study about the growth of certain tomatoes. One of the batch used up soil and were able to give ten tons. Whereas the other batch used only hydroponics and hence were able to give about 60 tons. This proves that this method can almost produce 6 times the produce compared to the traditional farming.
Any kind of crop which is cultivated using this method gives high yields. Even though some plants can produce more than most others, even then amount of time needed to harvest is still faster compared to the older method that provides a quicker turn around for the farmers.
Problem with the controlled environment is mainly that most of the plants will not get the correct sunlight and also carbon dioxide which helps it to grow. But this problem is addressed by using lights and also infusing artificial carbon dioxide in the air.
There are some other ways to grow crops inside the green house. One of the methods is known as deep water culture. Roots of the crops are exposed to the air and then a pump that releases air out helps to grow. This method is perfect for grapes and some other crops which are cultivated in this method.
Yet another method that is similar to the deep water culture method is the aeroponics. In this the plants are again raised in air and all nutrients here are put together in the form of mist or fog that also reaches all the crops to enable it to grow.
In drain and flood , one tray holds all the nutrients. Roots of the specific plant is held using foam chips or even clay pebbles and then at particular times in the day, this is then flooded for the plants to be able to get the correct requirements to enable growth. Then afterwards, this sort of drains itself.
One of the best things about this hydroponics gardening is the fact that it doesn't use a lot of area. This generally allows a person to put up the greenhouse even in the backyard. Only thing mainly needed is water placed in containers, and also tubes to reuse all the water taken in by the plants, also strong lamps must be used for artificial lighting and also some of the organic nutrients which are generally available in the gardening store.
