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.

Scientific Claim

Blue light exposure was associated with a 64% reduction in plant height in Henong 60 soybean cultivar (from 36.90 cm to 13.28 cm) and 65% in Heinong 48 (from 38.18 cm to 13.50 cm) compared to darkness conditions.

Original Statement

“HN60 Darkness 36.90 ± 0.29 a; BL 13.28 ± 0.82 b; HN48 Darkness 38.18 ± 0.22 a; BL 13.50 ± 0.54 b (Table 1)”

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The study design allows observation of associations between light conditions and plant height. The claim uses 'associated with' correctly and avoids causal language.

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.

85%

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.

81%

Blue light made soybean stems thicker by increasing the water-conducting tissue area and shortening the cells, which stopped them from growing taller.

80%

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.

77%

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.
