A testcross involves crossing a heterozygous individual with a homozygous recessive individual. If the plant is heterozygous for both traits (ligules and green leaves), the genotype would be LlGg. The testcross would be with llgg. The progeny would have a 1/4 chance of being green and liguleless (llGg or llgg).
