Nodulation of bean plants, Phaseolus vulgaris L., in water culture was poor during hot sunny weather in the greenhouse. It did not improve when indoleacetic acid, kinetin, gibberellic acid, purines and pyrimidines, yeast and soil extract were added. Nodulation was enhanced by adding used culture solution of nodulated pea or bean plants or an extrac...
The two main factors for bolting and flowering of endive were temperature and light; their influence on both growth and development was investigated.From experiments with successive dates of sowing, different raising temperatures and different growing conditions the following facts emerged: with increasing raising temperature, crop weight increased...
The effect of root temperatures on growth, water uptake and ion uptake of the maize single cross K 64r X E 184 has been studied during the early vegetative phase in culture solution in temperature-controlled rooms. A root temperature range of 5°-40°C with 5°C increments, a constant air temperature of 20°C, and a constant light intensity were employ...
