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.

Scientific Claim

Blue light exposure was associated with decreased gibberellin A3 (GA3) levels in the hypocotyls of both soybean cultivars (Henong 60: 48.28 ng/g to 41.47 ng/g; Heinong 48: 54.00 ng/g to 43.71 ng/g) compared to darkness conditions.

Original Statement

“HN60 Darkness GA3 48.28 ± 0.54 a; BL 41.47 ± 0.69 b; HN48 Darkness GA3 54.00 ± 0.84 a; BL 43.71 ± 1.02 b (Table 3)”

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The claim uses 'associated with' and presents measured data without implying causation, which aligns with the observational study design.

Similar Assertions

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.

84%

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.

81%

Under blue light, the stress hormone salicylic acid increased by about 56% in tall soybeans and 41% in short soybeans compared to plants grown in the dark.

79%

Blue light made a key salicylic acid protein (NPR1) increase by 40% and a gibberellin receptor protein (GID1) decrease by 18% in soybean stems.

78%

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.
