“…Germination and growth test results of waterlettuce and giant reed seeds were found to be consistent with research in that studies reported that the seeds of giant reed are inviable (Wijte et al 2005), as well as reported statements of the abundance of flowering waterlettuce and the presence of seeds, but observed seedlings being rarely found (Hall and Okali 1974). Both waterlettuce and giant reed seeds had 0% (0/100) germination and viability rates.…”

“…Seeds were chemically scarified with a 20% vinegar solution, which was found to break or soften the seed coat without damaging the seed embryo while still encouraging germination (Patil and Dadlani 2009). Temperature, moisture content, and time span within the incubator chamber were based on seed germination and propagule growth requirements used in related research experiments (Barrett 1980;Chadwick and Obeid 1966;Hall and Okali 1974;Lal and Gopal 1993;Netherland 1997;Wijte et al 2005). The incubator chamber temperature was monitored and checked daily with a ERTCO ASTM thermometer (Thermo Scientific Lafayette, NJ), and moisture levels were monitored and checked daily by sight, where the filter paper in petri dishes was kept moist with distilled water when necessary.…”

The purpose of this study was to determine the effect of whole-plant composting on the viability of seeds and other propagules of the invasive plant species waterhyacinth, waterlettuce, hydrilla, and giant reed while producing a valuable compost product. Invasive species were subjected to preliminary germination and growth tests and oven mortality tests to evaluate whether species distribution was via seeds, vegetative propagules, or both, as well as whether the composting process had the potential, through the high temperatures obtained, to kill seeds and other propagules. Germination and growth tests determined the means by which invasive species spread. Oven tests determined the temperatures at which unscarified and scarified seeds and propagules were rendered inviable. Achieving temperatures of at least 57.2 C was necessary within constructed compost piles to effectively kill the plants without the danger of redistribution. In the field, the study successfully developed a large-scale composting operation using invasive plant species as the primary feedstock. Analysis of field-scale composting showed final materials were within satisfactory to ideal levels for samples analyzed by the U.S. Compost Council's Seal of Testing Assurance Program and were, therefore, a valuable compost product.

“…These results are in accordance with information from Boose and Holt [14] about minimum size of rhizome and ability to regenerate; also with Wijte [15] about the new sprout emergence in giant reed. Wijte [15] studied the regeneration capacity of stems, observing that even stem fragments as small as an axillary bud (2 × 1 cm) can result in the growth of a new plant.…”

“…Wijte [15] studied the regeneration capacity of stems, observing that even stem fragments as small as an axillary bud (2 × 1 cm) can result in the growth of a new plant. At 60 DAP (the point at which biomass was measured), the biomass of the longest rhizomes (S3) had significantly increased, however the shredded rhizomes (S4 <1 cm) showed no occurrence of new sprouts during this assay and therefore no significant increase in biomass.…”

Studies were conducted under controlled conditions to determine growth and reproductive capabilities of Arundo donax L. (giant reed), a riparian invasive perennial plant that has spread widely. Greenhouse experiments were conducted to determine the influence of rhizome size and moisture content in the early invasiveness ability of giant reed. We tested different sizes of rhizomes: rhizome size of 1 cm, 3 cm, 5 cm and shredded rhizome. (fragments < 1 cm). These rhizomes were observed at 7, 14, 21, 28 and 35 days after planting (DAP). To test the effect of moisture content we used fresh rhizome fragments; rhizomes with moderate dehydration (50%); rhizomes with high dehydration (over 70%) with 48 hours of rehydration and rhizomes with high dehydration (70-90%). The rhizomes monitored for moisture content and biomass increase were between 3 and 5 cm, and were observed 60 DAP. The initial size of rhizomes affected the level of sprouting. Rhizomes with low moisture content (due to dehydration) showed high increase in biomass compared with the rhizomes that had not been treated or had been dehydrated and then rehydrated. Our results indicated that size of rhizomes is related to regrowth and low moisture (dehydration) content can be overcome by this species. This could be linked to high rates of colonization and early establishment ability of this species even after mechanical treatment of rhizomes, in riparian environments.

“…Nowadays, developed protocols are available on these regards. [30][31][32] In the past 22 and recently, [33][34][35][36][37][38] open field propagation methods using stem cuttings has been reconsidered and studied. This technique seems to be technically and economically reasonable 39 however, a better understanding regarding the influence of the type of propagating organ and its characteristics (e.g.…”

The increasing interest in Arundo donax, a perennial lignocellulosic species only reproducing by propagation, requires the setup of cheap, simple and reliable techniques. Considering these targets, stem cutting offers considerable advantages. The present investigation aimed to compare: i) plants obtained by different propagation methods (by rhizome and micropropagation mother plants); ii) plants obtained by stem cuttings from basal, central and apical parts of the stem; iii) different planting periods (spring, summer, autumn). The obtained results showed that the number of new shoots from stem buds was: i) higher in the spring and lower in the summer planting period; ii) higher from cuttings obtained by micropropagated than rhizome mother plants, both in spring and summer plantings; iii) decreasing passing from the basal to the apical stem portion; iv) partly unexpressed in the autumn planting period; v) lower from one-year stem cuttings as compared to two-year stem cuttings.
