Snow is still falling on the garden, blanching the uppermost leaves of the leeks still in the ground.
The mean leaf orientation value (LOV) and individual LOVs increased considerably during the time series of the genotypes, but more obvious changes in LOV occurred in the uppermost leaves.
But this stingy strategy also kept out carbon dioxide, reducing photosynthesis in the uppermost leaves.
The plants, which were at very late fruiting stage, appeared to be most similar to S. auriculata C. Jeffrey & Y. L. Chen in leaf shape and in the number of phyllaries, but different in the glabrous stem and petiole (vs. glandular pubescent), the exauriculate petiole (vs. auriculate), and the uppermost leaves obviously smaller than the middle ones (vs. almost equally sized).
Synotis baoshanensis is most similar to S. auriculata in leaf shape and in the number of phyllaries and florets, but differs by having the glabrous stem and petiole, the exauriculate petiole, the uppermost leaves obviously smaller than the middle ones, and the larger ray florets (4 4.5 mm).
Inoculations were carried out on three of the uppermost leaves.
Plant height was measured in the field as the shortest distance between the uppermost leaves and the soil surface; measurements were made from 25 replicates in each zone (Cornelissen et al. 2003).
Jinhai5, a corn cultivar planted widely across China, was grown at a density of 105,000 plants ha−1 until 3 days after silking (DAS), when plants were subjected to the removal of the uppermost and next leaves (S2), the four uppermost leaves (S4) or the six uppermost leaves (S6), with no leaf removal as control (S0).
In both flower types the uppermost green leaves have been identified as bracts, since they differ morphologically from both, sepals as well as leaves.
