Fiber content in relation to length and age of Sansevieria thunb. leaves
1945
Crane, J.C. | Alonso, R.E.
Investigations were conducted at the Cuban Agricultural Experiment Station on Sansevieria guineensis, S. zeylanica, and S. cylindrica to determine the comparative fiber content of their leaves as well as the relationship of fiber content to length and age of S. guineensis leaves. The average fiber content of leaves which had grown under practically identical environmental conditions and were approximately the same length and age was found to be 2.67, 2.16, and 1.53% for Sansevieria guineensis, S. cylindrica, and S. zeylanica, respectively. With an increase in length of leaf of Sansevieria guineensis, there was a progressive increase in the percentage fiber content accompanied by a progressive decrease in the percentage of moisture. Data, based on morphological development of the leaves, are presented which also show that there is an increase in the percentage of fiber accompanied by a decrease in the percentage of moisture. From a 7- to 8-year-old planting of Sansevieria guineensis, 3,210 pounds of dry, clean fiber were produced per acre but, on a commercial basis, doubt exists as to whether more than half of this amount would be produced annually at the end of the fourth or fifth year. A short discussion is presented dealing with some of the problems which need scientific investigation before the technicalities of Sansevieria fiber production are solved.
