environments the plants survive. One of the most important aspects of a tree surviving is the root system which is what this chapter explains next along with the other important functions for survival. The roots are not as simple as one may think though‚ as Jane Goodall goes into describing the variety of roots‚ some grow from the ground‚ above the ground‚ and on the tree trunks and house like vines. Roots are adaptive

and more than 90% in salt-sensitive cultivars (cv. Sirio and Lechoso) with the highest salt dosage during the reproductive growth. We show that the higher NaCl tolerance of the ILC1919 cultivar is supported by the less N2 fixation inhibition‚ a higher root-to-shoot ratio‚ normalized nodule weight and shoot K/Na ratio; and a reduced foliar accumulation of Na+ . Moreover‚ our results reveal the effectiveness of these nutritional and physiological indicators in the selection of salinity-tolerant chickpea

system‚ also known as Deep Water Culture‚ is a method of plant propagation where the roots are suspended in nutrient which have rich in oxygenated water. It is essentially a top fed deep water system which pumped from the reservoir to the top of the roots. Thus‚ it helps significantly in enhancing growth in the first few weeks. This technology has advantages when being set up in the process of experiment. The roots get easy access to water from the beginning. It has high yields compared to the amount

while providing an income for the ginseng grower with a modest investment? Wild and cultivated ginseng produce an annual crop in the United States and Canada valued in excess of $25 million. The price of wild root is about three times that of cultivated root. Because ginseng root is valuable‚ many overzealous collectors dig all plants from wild populations. They often fail to reseed‚ and as a consequence‚ there is serious concern about the survival of American ginseng in the forest ecosystem

it is unwanted. It is funny that even if you take all the measures to avoid weeds from growing it somehow manages to grow and spoil the flower near it. Weeds are very worrying as they tend to be toxic and can be predatory at times. Due to its vast root system it tends to absorb all the water and sunlight and leaves a very less amount of water to the flower/plant growing near it. It is better if we remove the weed when it is very small and still needs to bud as it can quickly grow and disperse. Weeds
