Table 3 Mean productivity of T 0 plants, the weight and relative CKX activity in the roots of cv. Golden Promise transformed with a silencing cassette of HvCKX2 gene via the Agrobacterium -mediated method

From: HvCKX2 gene silencing by biolistic or Agrobacterium-mediated transformation in barley leads to different phenotypes
