This series explores current environmental issues and instills in children an ecological consciousness that will remain with them throughout their lives.
A tree in Caillou’s backyard was damaged by a bad storm and has to be cut down. This makes Caillou sad, but Daddy brings him to the nursery to help choose a new tree. While looking around, Caillou learns about trees and their importance to the environment, the animals, and to humans. After planting the new tree, the birds and squirrels agree with Caillou: he found the perfect tree for their backyard.
The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume I contains accounts of all the Monocotyledons, which includes those groups known informally as the 'petaloid monocotyledons' (the Liliaceae and Amaryllidaceae in the first edition, divided here among 17 families), the grasses and sedges (Gramineae and Cyperaceae), the aroids (Araceae) and the large and diverse Orchidaceae.
Plants are subjected to a variety of abiotic stresses such as drought, temperature, salinity, air pollution, heavy metals, UV radiations, etc. To survive under these harsh conditions plants are equipped with different resistance mechanisms which vary from species to species. Due to the environmental fluctuations agricultural and horticultural crops are often exposed to different environmental stresses leading to decreased yield and problems in the growth and development of the crops. Drought stress has been found to decrease the yield to an alarming rate of some important crops throughout the globe. During last few decades, lots of physiological and molecular works have been conducted under water stress in crop plants.
