In short soybeans, adding brassinolide hormone made stems grow longer under blue light but shorter in the dark, showing light-dependent effects of this hormone.

Scientific Claim

In Heinong 48 soybean cultivar, brassinolide (BR) supplementation under blue light enhanced hypocotyl length compared to blue light alone, but suppressed growth in darkness.

Original Statement

“BL + BR showed increased hypocotyl length in HN48 at 2, 3, and 4 days; D + BR suppressed hypocotyl growth in darkness (Figure 3d)”

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The claim accurately describes experimental outcomes without causal language, reflecting the observed light-dependent BR effects.

Similar Assertions

When soybean plants were exposed to blue light, their height dropped by about two-thirds compared to plants grown in the dark, with both tall and short varieties showing similar reductions.

72%

Blue light made the levels of a key growth hormone (GA3) drop by about 14% in tall soybeans and 20% in short soybeans when grown in the dark versus under blue light.

71%

Blue light raised the stress hormone jasmonic acid by about 15% in tall soybeans and 38% in short soybeans compared to plants grown in the dark.
