查询词典 cultivars

The probing behaviors of the tea green leafhopper, Empoasca vitis Gothe, on nine tea cultivars were studied by videotext Direct Current-Electrical Penetration Graph, i. e. DC-EPG. Following seven types of waveforms produced by the leafhopper stylet probing were determined: A, stylet pathway formation; S, salivation when stylets pierce into and stay in phloem; C, active ingestion before stylets reach phloem; E and F, passive ingestion in phloem; R, the insect resting with its stylet inserted into the leaf tissue and NP, not probing.
