Plants culture in space environment for feeding food to the space travelers

Abstract

Differential growth responses of plants to gravity know as gravitropism, the geotropic plants were familiar to humans by the nature of their use. However, the plants can grow successfully in low gravitational force, microgravity and no gravity too. This is the most important aspect of science in this era to focus on the supply of dietary food as live healthy greens to the space-travelling astronauts during prolonged spaceflight. Hence, the space culture aided to provide food in spacecraft. The effort to grow the agricultural or horticultural plants in space has limited success so far. In this view, the devising of technology has worth pursuing to prepare of space activities, with potential low, microgravity or no gravity aspects in the closed space plant growth system with the nutrient release arrangement. However, the plant-like lettuce, cabbage, cauliflower, amaranths, radish, turnip, endive, Swiss chard, dandelion, New Zealand spinach and other vegetables were underway evaluation for their suitability to the space culture.
