IPSGA 15th International Conference

[Neil Olszewski]

Because some have only recently received the circular containing 
registration and abstract preparation materials, the deadline for
submission of abstracts for the 15th International Conference
on Plant Growth Substances has been extended to April 15, 1995.   
Other deadlines remain unchanged.

For those unfamiliar with this meeting, a description of this 
meeting and the program follows.  Registration and abstract 
preparation information can be obtained from:

The International Plant Growth Substances Association (IPGSA) 
will hold its 15th International meetings in Minneapolis, 
Minnesota from July 14 through July 18, l995.  

All scientific sessions will be held at the headquarters hotel, 
the Hyatt Regency, in Minneapolis.

This meeting will be held in conjunction with the Annual Meeting 
of the Plant Growth Regulator Society of America, and joint 
sessions are being planned that emphasize applied aspects of 
plant growth regulation.  The PGRSA meeting will run from the 
morning of Tuesday, July 18, through lunch on Thursday, July 20.

The deadline for submission of abstracts has been extended to 
April 15, 1995, and the deadline for early registration (at a
