Early-Life History of the White Sucker (Catostomus Commersoni) in Lake Taneycomo, Missouri
White suckers (Catostomus commersoni) were monitored during the 1994 and 1995 spawning periods to determine location and timing of reproduction, dispersal of larvae, and growth of sub-adult fish. Daily aging by the use of otoliths from lab reared white sucker larvae was validated to 28 days. …

Efficacy of Sucker Control Method and Effect of Topping Height on Axillary Bud Growth in Dark Fire-Cured Tobacco
The removal of terminal buds (topping) and sucker control are two practices that have an impact on yield and quality of dark tobacco (Nicotiana tabacum L.). Topping breaks apical dominance and encourages the growth of axillary buds (suckers). Following topping, growth regulator chemicals known as …

The effect of post-harvest ammonium sulphate application, planting time and sucker size on plant growth and yield of queen pineapple, ananas comosus
… plantings are currently established from suckers taken from harvested plants. The speed and development of suckers on the mother plant is not rapid enough to be used as planting material at fruit harvest. Therefore, suckers are left to grow on the mother plant for 6 to 8 months after …
