The growth rate of excised soybean (Glycine max [L.] Merrill) embryos grown in liquid culture increased linearly as photoperiod was increased from 0 to 20 h at an irradiance of 9 W m-2 measured between wavelengths of 700-850 nm from clear i...
The role of hormone transport and metabolism in apical dominance in oats [0.03%]

14C-benzyladenine (BA) and 14C-indole-3-acetic acid (IAA) were used to study hormone transport to the tiller bud and hormone catabolism in excised oat stem segments. Acropetal BA transport was greatest from upright stem segments to tiller b...
Expansion and photosynthetic rate of leaves of soybean plants during onset of and recovery from nitrogen stress [0.03%]
大豆植株在遭受和缓解氮胁迫期间的叶片扩展及光合速率变化研究

This study reports on the effects of nitrogen stress and restoration of nitrogen availability after a period of stress on expansion and photosynthetic rate of soybean leaves of differing maturity. We hypothesized that nitrogen resupply woul...
Nitrogen and dry-matter partitioning in soybean plants during onset of and recovery from nitrogen stress [0.03%]
大豆植株氮素胁迫起始和恢复期间的植株含氮量和干物质量分配研究

L Tolley-Henry
The study tested the hypothesis that resupplying nitrogen after a period of nitrogen stress leads to restoration of the balance between root and shoot growth and normal functional activity. Nonnodulated soybean plants were grown hydroponica...
Kinetics of shoot inversion-induced ethylene production in Pharbitis nil [0.03%]
牵牛花茎段转置处理后乙烯产生动力学研究

Shoot inversion promotes a significant increase in ethylene production in the inverted part of the Pharbitis nil main shoot. The latent period for shoot inversion-induced ethylene production is ca. 2.75 h. Our results indicate that the shoo...
Assessment of an apparent relationship between availability of soluble carbohydrates and reduced nitrogen during floral initiation in tobacco [0.03%]
烟草开花启动期间可溶性碳水化合物和还原氮类物质之间关系的评估研究

C D Raper Jr et al.
Daily relative accumulation rate of soluble carbohydrates (RARS) and reduced nitrogen (RARN) in the shoot, as estimates of source strength, were compared with daily relative growth rates (RGR) of the shoot, as an estimate of sink demand, du...
Internode and petiole elongation of soybean in response to photoperiod and end-of-day light quality [0.03%]
光周期和每日光照质量对大豆节间和叶柄伸长的影响
J F Thomas,C D Raper Jr
J F Thomas
Elongation of main stem internodes and petioles of soybeans, Glycine max 'Ransom,' was examined in response to various photoperiod/temperature combinations and to end-of-day (EOD) light quality. Photoperiod treatments consisted of 10, 14, a...
Soluble carbohydrate allocation to roots, photosynthetic rate of leaves, and nitrate assimilation as affected by nitrogen stress and irradiance [0.03%]
氮胁迫和光照对可溶性碳水化合物在根系中的分配、叶片的光合速率及硝酸盐同化的影响
L T Henry,C D Raper Jr
L T Henry
Upon resupply of exogenous nitrogen to nitrogen-stressed plants, uptake rate of nitrogen is enhanced relative to nonstressed plants. Absorption of nitrogen presumably is dependent on availability of carbohydrates in the roots. A buildup in ...
