Adaptation to flooding in upland and lowland ecotypes of Cyperus rotundus, a troublesome sedge weed of rice: Tuber morphology and carbohydrate metabolism
(Oxford University Press, 2008-05-30)
Background and aims
In recent years, Cyperus rotundus has become a problem weed in lowland rice (Oryza sativa) grown in rotation with vegetables in the Philippines. As the growth of C. rotundus is commonly suppressed by prolonged flooding, the ability of the weed to grow vigorously in flooded as well as upland conditions suggests that adapted ecotypes occur in these rotations. Studies were conducted to elucidate the mechanisms that permit C. rotundus to tolerate flooded soil conditions.
Methods
Upland and lowland ecotypes of C. rotundus were compared in terms of growth habit, carbohydrate reserves and metabolism, and activities of enzymes involved in alcoholic fermentation – alcohol dehydrogenase (ADH) and pyruvate decarboxylase (PDC).
Key Results
The lowland ecotype has much larger tubers than the upland ecotype. Prior to germination, the amylase activity and total non-structural carbohydrate content in the form of soluble sugars were greater in the tubers of lowland plants than in those of upland C. rotundus. At 24 h after germination in hypoxic conditions, PDC and ADH activities in the lowland plants increased, before decreasing at 48 h following germination. In contrast, ADH and PDC activities in the upland plants increased from 24 to 48 h after germination.
Conclusions
Tolerance of lowland C. rotundus of flooding may be attributed to large carbohydrate content and amylase activity, and the ability to maintain high levels of soluble sugars in the tubers during germination and early growth. This is coupled with the modulation of ADH and PDC activities during germination, possibly to control the use of carbohydrate reserves and sustain substrate supply in order to avoid starvation and death of seedlings with prolonged flooding....

Macrofloral diversity of Bulabog-Putian Natural Park, Dingle, Iloilo, Philippines
(Silliman University, 2010-01)
Macrofloral species richness, relative density, relative abundance and diversity index of the protected forest and riverine ecosystems of Bulabog-Putian Natural Park, Dingle, Iloilo, Philippines were determined employing the modified quadrat method. There were 68 families, 170 genera, and 218 plant species listed in the entire study area of 0.16 hectare. The riverine ecosystem had a higher species richness (S=137) compared with the protected forest ecosystem (S=126). The top three major families observed in the protected forest ecosystem were Euphorbiaceae, Moraceae, and Annonaceae families and for the riverine ecosystem they were the Moraceae, Poaceae, Euphorbiaceae and Papilionaceae families. Plant genera that belong to the families Euphorbiaceae and Annonaceae dominated the protected forest ecosystem and the plant genera belonging to families Poaceae and Cyperaceae dominated the riverine ecosystem.
Relative abundance in the herb-dominated riverine ecosystem forest ecosystem with values of 43,466 and 7,007 individuals, respectively. Computed diversity index was higher in the riverine ecosystem (H’=3.30) than the protected forest ecosystem (H’=2.69), both categorized as areas of moderate level of species diversity. In the entire study area, 28 (12.84%) plant species are known to have threatened conservation status; three of these are critically endangered, namely kamagong (Diospyros philippensis Desr.) Gurke), prickly narra (Pterocarpus indicus Willd. forma Echinatus), and red lauan (Shorea negrosensis Foxw.). Endemic plant species were inventoried that need to be conserved and protected.
This study provides comprehensive baseline information on the macrofloral diversity of Bulabog-Putian Natural Park. Data gathered from this study will enhance knowledge on biodiversity for the local or national government to implement strong conservation and protection programs for the endemic and indigenous plant species in their natural habitat and to prevent biodiversity loss that may be aggravated by climate change....
