Ethylene-Mediated Growth Response in Submerged Deep-Water Rice

摘要: Floating or deep-water rice is mainly grown in the floodplains of Southeast Asia where water can rise up to 6 m during rainy season (1). Deep-water has great agronomic importance because it a subsistence crop many densely populated areas no other be grown. The distinguishing characteristic this its ability elongate with rising waters after 4–6 weeks growth. survival plant depends on keep part foliage above surface. Completely submerged plants cease and eventually die (2). When lower leaves become submerged, their growth also stops they so that basal partially consists elongated internodes only. total height reach 7 high flood levels (3). This remarkable elongation occurs spite severely restricted supply O2 CO2 under water.
