Abstract

Abstract: Taking Petunia hybrida double waterfall, single dream and single carpet as materials, the effects of temperature on the growth and development of P. hybrida were studied. The results showed that the growth and development of P. hybrida were influenced by temperature, the optimum temperature was 16~25 ℃, the plant height, crown width, lateral branches and the number of flowers increased the most at the constant temperature of 21~25 ℃, while the plants grew spindly and the number of flowers decreased when the temperature was 25~35 ℃. Temperature higher than 35 ℃ or lower than 15 ℃ inhibited the growth of P. hybrida, reduced disease resistance, large area of leaves wilting, or even dead.

Key words: Petunia hybrida, temperature, growth and development
