tion after 18 days was similar, regardless of storage conditions. Gib- 
berellic acid did not affect germination after cold storage treatments. 
Seeds stored under wet and cold conditions remained viable through 
July 1974. 
Seeds planted 23 March 1974 in a 10- by 12-foot wave-protected plot 
(Block IV) failed to establish. Many seeds were germinating at time of 
planting. Seeds planted the same date in rows in Block V also failed 
to establish. 
Soil samples collected at the shoreline, 50 and 150 feet from 
shore, on 20 June were returned to the laboratory. After 3 weeks no 
seedling plants were observed in any of the samples. If viable seeds 
were present in the soil samples they should have germinated within 
this time interval. Smooth cordgrass seeded into 11 soil samples col- 
lected from the study blocks and moistened with seawater had a 33 percent 
germination rate. Thus, the soil or its inherent salinity was not a 
factor in seed germination. 
VII. TIME AND COST 
Saltcedar required the least amount of time to transplant. The 
stems could be pushed into the ground without digging (Table 27). 
Saltgrass was easily dug, separated, and planted. Seedlings of black 
mangrove could be pulled from the soft mud with little trouble. Separa- 
tion was not necessary, reducing the time requirements for transplanting. 
Needlegrass grew in large bunches with rhizomes. The material was not 
difficult to dig, but did require separation which was not difficult. 
Many culms of smooth cordgrass could be pulled from soft mud or easily 
dug, and separation by hand was usually easy. Gulf cordgrass was hard 
to dig during dry conditions but the large clumps could be separated 
by hand. Saltmarsh bulrush was hard to dig in most instances because 
individual plants had to be removed from masses of saltgrass roots. 
Pulling was more efficient time-wise then digging but stems often broke. 
Common reed was difficult to dig because of the massive root structure 
and rhizomes. Separation and cutting of stems were also necessary. 
Big cordgrass possessed a deep root system and grew in a soil that re- 
quired extensive digging. Separation of plants and cutting of stems 
also took time. American bulrush grew in a location often covered by 
water. Extensive digging was necessary to extract the root system. 
Giant reed required picks and shovels to dig, but plants were collected 
relatively fast. Cutting of rhizomes by axe, pick axe, or edge of 
shovel was necessary for separation of plants. Large holes were 
necessary to plant the rhizomes. Olney bulrush was difficult to dig, 
separate, and plant and required the greatest amount of time. 
Planting required more time than digging or separating, regardless 
of species. Mechanical instead of manual operations could greatly 
change time requirements for each species. Man-hours and vehicles 
required to transport each species from source to planting site were 
not compiled since that time was variable.
