Successful afforestation has been practiced in South Africa for more than a century. Recently, however, problems with afforestation of pines have occurred in the northeastern part of the Eastern Cape Province. Rapid mortality of Pinus patula and P. elliottii have occurred when small container seedlings were planted on old-agricultural soils. Death would often occur within 5 months of planting. ...

Increasing use of frozen storage in nurseries at northern latitudes calls for thawing methods that are safe, economical and easy to apply on a large scale. The easiest and most economical method would be to thaw seedlings in the same boxes they were stored in. However, doing this safely requires more knowledge about how long and at what temperatures seedlings should or can be kept in the boxes ...

INTRODUCTION Ecological restoration is a rapidly growing field of biology. Grassroots restoration activities have a long history and have recently increased dramatically. These are now being supplemented by state and federally sponsored restoration projects reaching tens and hundreds of millions of dollars, like those in the Everglades, Lake Tahoe, and the Sacramento River and Delta. Academic p...

Following si te preparation, three cultural t reatments and three open-poll inated loblolly pine (Pinus taeda L.) families were studied on a .gently sloping Beauregard silt loam in central Louisiana. The treatments were: (1) fertilization (either broadcast application of 177 kg N and 151 kg P/ha or none); (2) herbicide application (either broadcast application of herbicides during the first thr...

In order to test the effect of adding various organic materials to the min eral nutrient medium of Phaseolus lunatus (Burpee's Bush Lima Beans), it was felt desirable to develop a technique for growing them in such a way that the root system would be in a sterile medium. Growth of lower plants (funai and algae) in such a medium is standard procedure. Moreover, some such work with higher plants ...

Catifornia species. T propagation and establishment of woody seedlings are important aspects of many forest ecosystem restoration efforts. Two factors that play iraportant roles in successfully growing woody plants are the size and overall quality of the seed and whether or not the seedlings are grown in containers. In this paper, we examine how container size, acorn size and shell integrity, a...
