To supplement information on its life history and verify whether carpospores can be used for seedling culture, early development of G. turuturu was investigated under culture conditions （27~C, 10-13 ~mol/（mZ.s） in irradiance, photoperiod 10：14 h L：D）. Three physiological stages were recognized by continuous microscopic observation： division stage, discoid crust stage, and juvenile seedling stage. At the beginning of the division stage, the carpospores developed germ tubes into which the carpospore protoplasm was evacuated, and then the carpospore protoplasm in the germ tubes began to divide continuously until discoid crusts formed. Finally, upright thalli appeared on the discoid crusts and developed into juvenile seedlings. It took about 60 days for carpospores to develop into juvenile seedlings. The growth parameters, including germination rate for carpospores and discoid crust diameter, were recorded. These results contribute more information on the life cycle, and at the same time are of great significance in the scaling-up of artificial seedling cultures of G. turuturu.展开更多

All activities revolving around the use of a horse as entertainment, sport or business play a role in the ＂horse industry＂. These activities take place due to the existence of people demanding horses and a variety of goods and services associated with them Previous studies reveal that as income per capita becomes larger, the equestrian demand increases and, consequently, the global expenditure incurred by those individuals interested in horses. More than 500,000 horse, 9,000 breeders and 50,000 equestrian businesses, show the economic importance of the equestrian sector in Spain. That part of global expenditure that adds to the GDP of a country is what is generally defined as economic impact of the sector. Its relation will depend mostly on： the percentage of the expenditure that adds to national production and the participation in the country＇s global expenditure of those domestic goods and services associated with the equestrian demand. The activities related to sports are those with most economic impact, about 8,000 ∈ per horse, measured as total expenditure or with respect to the employment that they generate in the economy.展开更多
