Other claims from this paper (6)

Observation Significant genotypic variation was observed in leaf area and total dry weight among soybean genotypes.
Intervention effect Under water stress, LA and TDW of Hwanggeumkong and Paldalkong were more sensitive than those of the other cultivars.
Intervention effect Suwon 93, with small LA, was insensitive to water stress in LA.
Intervention effect Leaf proline and ABA contents increased after water stress.
Intervention effect The yield reduction of Hodgson 78 under water deficit was severe compared with the small reduction in Baegunkong.
Observation Baegunkong showed relatively greater yield stability and higher average yield across soil water potentials.

Other claims from this paper (9)

Association At lower density, fruit productivity declined slightly with tree age from 1.21 to 1.00 kg/m2.
Association At higher density, fruit productivity declined with age from 0.93 to 0.50 kg/m2.
Intervention effect Higher planting density had larger LAI and crown density at any age.
Association Fruit productivity was nearly stable below LAI 5 and crown density 80%.
Association Fruit productivity declined above LAI 5 and crown density 80%.
Association Early yield growth mainly depended on rapidly increasing LAI or crown density.
Intervention effect At 11 years, both density groups yielded about 60 t/ha.
Intervention effect Higher density yielded more before age 11.
Intervention effect Lower density yielded more after age 11.
