Hydraulic resistance Leaf sheath Maize Napiergrass Nodal stem
2009/7/8
The hydraulic resistances of each organ in napiergrass and maize shoots were measured with a pressure flow meter. The results obtained were as follows: 1) Hydraulic resistances of the shoot, leaf and ...
Changes in Dry-matter Weight, Leaf Area and Photosynthetic Rate after Soil Drought Stress in Napiergrass (Pennisetum purpureum Shumach.) and Maize (Zea mays L.)
Leaf area Maize Napiergrass Photosynthetic rate Soil drought treatment Total dry matter weight
2009/7/8
Recovery of dry-matter production after drought stress is an important factor of drought resistance in plants. Napiergrass, whose dry matter weight largely decreased by soil drought treatment, increas...
