Germination capacity of tomato seeds (lycopersicon esculentum mill)" from the farmer to osmotic stress in different photoperiods

Abstract

Among the horticultural crops, the tomato is considered of great importance in the province of Santa Elena, an area in which it has stopped sowing in the last 8 years with the same intensity, due, among others, to the serious problems of salinity in soils, including fresh water sources, which currently have a high content of salts that impede the normal growth and development of vegetables. It indicates that the life cycle in the tomato plant is not annual as it is normally believed; it is annual only due to weather conditions; It can be annual poly and of different duration, according to the variety. There are, in fact, types of remarkable vigor that continually produce axillary buds and others (dwarfs, called pruned autos) that stop their growth and further development. Depending on the growth habit, there are certain and indeterminate growth varieties. The determined plants that allow a higher planting density and the indeterminate growth varieties that produce more bunches and grow indefinitely (ALDANA A. 2004). Himself LORENTE H. (s.f.) indicates that the determined plant is of a shrub type, small, small and of early production, it is characterized by the formation of inflorescences at the end of the apex. The indeterminate type tomato grows up to 2 meters in height, or more, depending on the tutoring applied.
