Perhaps you should try some spelling variations:
"plant technologies" » "pnt technologies", "plasma technologies", "agent technologies"
"implant technology" » "impact technology", "implement technology", "inoculant technology", "implant biotechnology", "implasma technology", "imagent technology"
"plant technology" » "plant biotechnology", "plasma technology", "agent technology"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("plant technology") OR ("implant technology"))) OR ((("plant technologies") OR ("smart technologies"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"plant technology\") OR (\"implant technology\"))) or (((\"plant technologies\") or (\"smart technologies\"))))*".
• Removing quotes may allow a broader search: (((( plant technology ) OR ( implant technology ))) or ((( plant technologies ) or ( smart technologies ))))*.
