Accumulation and Partitioning of Dry Matter in Taro [Colocasia esculenta (L.) Schott]

Dry matter accumulation and partitioning of two taro (Colocasia Esculenta (L.) Schott) cultivars under Inceptisol soils in Samoa

“…Finally, the TDM which is dominated by the corm and suckers dry matter gradually accumulated until the final harvest at 175 DAP. Therefore, the TDM accumulation of Samoa 1 and Samoa 2 cultivars of taro is in accordance with the other studies on taro conducted elsewhere (Goenaga, 1995;Sivan, 1976).…”

“…The PDM of Samoa 1 accumulated over time from 4.8 to 94.95 g/plant during the 35 to 140 DAP time period while the petioles dry matter for Samoa 2 also increased from 6.8 to 119.9 g/plant at 35 to 140 DAP. The above results are similar to the results of PDM by other researchers whereby the PDM increased from planting until at least 100 DAP and then declining afterwards (Amosa, 1993;Goenaga, 1995;Sivan, 1976). …”

“…There are large drops in the RDM of Samoa 1 and Samoa 2 at 175 DAP. The reductions in RDM are in accordance with other growth stages of taro reported by other researchers ( Amosa, 1993;Goenaga, 1995;Lebot 2009;Pardales Jr., 1986;Sivan, 1976,). …”

“…According to Goenaga (1995), the growth of the two taro cultivars (Blanca and Lila) in Puerto Rico were characterized by three distinct stages. Stage 1 was dominated by the low rates of total dry matter accumulation during the first 48 DAP, followed by the rapid growth of total dry matter until 159 DAP whereby all plant parts experience improved dry matter accumulations.…”

Effect of indigenous storage method on performance of taro [Colocasia esculenta(L.) Schott] under field conditions in a warm subtropical area

“…The wide range of maturity time for taro may be associated with the lack of a clear definition of the stage of maturity, because of the crop's indeterminate growth habit (Singh et al, 1998). Harvest maturity in taro has been defined variously to include corm quality or average or maximum yield attainment (Miyasaka et al, 2003), change in corm shape (Jacobs & Clarke, 1993), cormel: corm ratio (Goenaga, 1995) and phenostage (Jacobs & Clarke, 1993). Despite the lack of consistency in determining a cominonly accepted harvest-maturity stage for taro, leaf area development has been generally used as an indicator of vegetative growth (Reynolds, 1977;Onwueme & Johnston, 2000).…”
