Petroleum Ether Separation and Seedcoat Removal Enhance Seed Germination of a Casuarina equisetifolia L. · C. glauca Sieb. ex Spreng Hybrid
Casuarina cunninghamiana Miq. is an introduced species to Florida that has potential as a windbreak plant to help manage canker in citrus groves; however, only Florida sources can be used for that purpose. Local sources of Casuarina are generally adequate seed producers, but germination percentages are frequently poor. Thus, the causes of low seed germination and methods to improve germination ...
متن کاملSpecificity and effectivity in nodulation by Frankia on southern hemisphere actinorhiza.
Nodulation ability was tested for Frankia strains HFPCcI3 and EL1, and Frankia sources A.t. and G.a. from Allocasaurina torulosa and Gymnostoma australianum, respectively, on A. torulosa Miq., Casuarina cunninghamiana Miq., G. australianum L. Johnson and Elaeagnus triflora Roxb. It was shown that A. torulosa and C. cunninghamiana formed nodules only with the Frankia sources obtained from their ...
متن کاملAerial Nodules in Casuarina cunninghamiana.
A complete survey of La Réunion Island showed that, in 40- to 50-year-old Casuarina cunninghamiana plantations located in the northeast at an altitude above 400 m, some trees bore aerial nodules as high as 6 to 7 m up the trunk. The nodules exhibited a significant specific acetylene reduction by the ARA method (0.77 mumol of C(2)H(4) per h/g [dry weight] of nodule) at the time of sampling (June...
متن کاملInitiation and Development of Root Nodules of Casuarina (Casuarinaceae)
Roots of seedlings of the "beefwood" tree, Casuarina cunninghamiana Miq. grown in nitrogenfree nutrient solution were inoculated with a suspension prepared from crushed root nodules taken from mature plants. Marked deformation of root hairs was evident but no infection threads were observed in root hairs. The mode of infection remains undetermined. Root nodules were initiated within three weeks...
متن کاملPermanent Draft Genome sequence for Frankia sp. strain CcI49, a Nitrogen-Fixing Bacterium Isolated from Casuarina cunninghamiana that Infects Elaeagnaceae
Frankia sp. strain CcI49 was isolated from Casuarina cunninghamiana nodules. However the strain was unable to re-infect Casuarina, but was able to infect other actinorhizal plants including Elaeagnaceae. Here, we report the 9.8-Mbp draft genome sequence of Frankia sp. strain CcI49 with a G+C content of 70.5 % and 7,441 candidate protein-encoding genes. Analysis of the genome revealed the presen...
