The terpenoid pathway is involved in synthesis of these hormones.

This hormone can stimulate bolting (sometimes flowering) in long-day plants.

The list below includes several reasons why high levels of salinity are INDIRECTLY injurious to most plants. Choose the SECOND of the two options in the list that indicates INDIRECT reasons why saline soils are harmful to most plants.

This hormone causes epinasty directly (rather than indirectly); for example, in anaerobic conditions.

This hormone breaks dormancy in VARIOUS tissues (BOTH seed AND bud tissues).

Which plant phytochrome responses are photoreversible?

This hormone directly triggers abscission.

  Specific mechanisms for saline tolerance:  Earlier in the test, in questions 51 and 52, you were asked about two general strategies which allow some plant species to tolerate saline conditions.  For this bonus question, type each of those general strategies here, and then below each one, describe at least two specific mechanisms of salt tolerance for each of those general strategies, including all relevant details. Every specific mechanism should be typed on a separate line.  

These hormones are synthesized mainly in young tissues.

The terms listed below include some environmental variables that are cues important in controlling flowering in many species.  Select the SECOND listed environmental cue that is important in controlling FLOWERING.
