The Nature of Waterlogging Tolerance of Loblolly Pine
نویسندگان
چکیده
--Loblolly pine seedlings develop many responses under waterlogging stress that are similar to adaptations to waterlogging in other higher plants. Some of the responses of loblolly pine seem to be less specialized than those exhibited by true wetland species. Lack of specialization is some cases seems to account for growth differences in relation to soil nutrient level and length and type of waterlogging. Screening for various adaptations appears to lave some potential for early progeny testing for wet site loblolly pine

Determining the best form factor formula for Loblolly Pine (Pinus taeda L.) plantations at the age of 18, in Guilan- northern Iran
In order to determine the best form factor formula for Loblolly Pine (Pinus taeda L.) plantations in Talesh (Western Guilan province-Iran), a number of 110 trees were selected based on their distribution in diameter classes, from 12 to 34 cm (in a two- cm diameter interval). First, several quantitative factors including diameter at breast height, diameter at 0.65 m of height, and diameter at st...
متن کاملUse of Excessive Waterlogging and Physiological Responses to Measure Genetic Variation in Loblolly Pine Waterlogging Tolerance
-Eleven sources of loblolly pine were studied for genetic variation in waterlogging tolerance and physiological responses to waterlogging. There were source differences in both though there were no correlations between them. Additional keywords: Pinus taeda, progeny tests, flooding, anaerobic metabolism The purposes of this study were to determine: a) if there was interspecific genetic variatio...

متن کاملSHORT COMMUNICATION Frequent fire protects shortleaf pine (Pinus echinata) from introgression by loblolly pine (P. taeda)
Across much of the globe, fire is a major disturbance agent of forest and grassland communities. The removal of fire from previously fire-maintained ecosystems, which has occurred in many areas, changes species composition, favoring later less fire tolerant species over fire-adapted ones. A recent measured increase in the rate of hybridization between the fire-adapted shortleaf pine (Pinus echi...
