Viability of Crassocephalum crepidioides Seeds due to Boron Application

Abstract

Boron (B) is a microelement that is needed in plant growth, because it plays an important role in the production of grain, increases carbohydrate transport and increases enzyme activity, if it is given in the appropriate amount. This study aimed to determine the concentration of Boron to obtain the best viability of the seeds of Crassocephalum crepidioides. The research was conducted at the greenhouse, using Random Block Design. The treatment was the concentration level of Boron, consisting of four levels (0%, 50 mg/L, 100 mg/L, and 150 mg/L), carried out in triplicate. The observed variables included the number of flowers (florets), number of seeds per flower, seed germination (%), speed of seed germination, and growth potential (%). The results showed that the number of flowers and the number of seeds per floret was not significantly different for all treatments tested. Boron concentration of 150 mg/L produces better performance in seed germination, speed of seed germination, and growth potential.
