“…Sena Gomes and Kozlowski (1986) studied the Catongo genotype and reported that, after the removal of flooding stress, plants did not absorb enough water to resume shoot growth as all their energy was directed towards root growth. During recovery, priority is given to root system development over the aerial parts to restore normal development (Kolb et al 1998, Parad et al 2016.…”

“…Hasil yang sama juga ditunjukkan pada penelitian ini bahwa terjadi peningkatan tinggi tanaman selama fase pemulihan yang didukung oleh pertumbuhan akar, kemampuan mempertahankan jumlah daun dan peningkatan kandungan pigmen fotosintesis. Parad et al (2016), menyatakan bahwa tanaman yang toleran terhadap penggenangan menghasilkan ATP yang lebih banyak sehingga produksi hormon tanaman seperti giberelin dan sitokinin mencukupi untuk melakukan pembelahan dan pemanjangan sel selama pertumbuhan.…”

Cabai rawit (Capsicum frutescens L.) merupakan salah satu tanaman yang memiliki nilai ekonomi tinggi dan daya adaptasi yang cukup luas. Curah hujan tinggi di Indonesia mengakibatkan lahan tergenang sehingga mengancam produktivitas tanaman, salah satunya cabai rawit. Tujuan penelitian ini untuk mengetahui respon dan toleransi tanaman cabai rawit (C. frutescens L.) varietas Pelita F1 terhadap penggenangan. Perlakuan terdiri dari kontrol (kapasitas lapang) dan perlakuan penggenangan selama 24 jam. Perlakuan menggunakan 2 atau 3 ulangan. Desain penelitian menggunakan RAL dan analisis data menggunakan ANOVA dan uji lanjut LSD taraf signifikan 5%. Hasil penelitian menunjukkan terjadi penurunan persentase layu, kerusakan ujung akar, penurunan kandungan klorofil a, klorofil b, klorofil total dan karotenoid setelah penggenangan. Tanaman terlihat segar, jumlah daun dipertahankan, terjadi pertumbuhan akar, peningkatan kandungan pigmen fotosintesis, tinggi tanaman dan berat kering pada akhir fase pemulihan. Terjadinya pertumbuhan diakhir fase pemulihan menunjukkan cabai varietas Pelita F1 toleran terhadap penggenangan 24 jam. Kemampuan tanaman dalam memperbaiki sistem perakaran, mempertahankan jumlah daun dan meningkatkan kandungan pigmen fotosintesis merupakan faktor penting dalam toleransi tanaman terhadap penggenangan.

“…Irrespective of the international consensus about the importance of wetlands and riparian areas for ecosystem health and the maintenance of biodiversity, wetlands and riparian areas are being destroyed faster than any other terrestrial ecosystem in the context of global climate change and human activities [1]. About half of this area has been lost, converted, or degraded in the last century.…”

“…About half of this area has been lost, converted, or degraded in the last century. Among the main factors related to wetland degradation are the clearing of vegetation, agriculture, ranching, and industrial usage, as well as environmental problems caused by global climate change and hydropower dam construction [1][2][3][4]. Every year, the flood-drought-flood cycle repeats itself.…”

Disentangling the underlying processes of plant adaptations to multiple abiotic stressors is crucial regarding promissory species for the restoration of riparian ecosystems prone to suffering extreme flood and drought events in the context of global climate change and human activities. Distylium chinense is a dominant evergreen shrub, distributed in the riparian areas of the Yangtze River in China. Here, one field study and five controlled experiments (Control, CK; single drought, D; single flooding, FF; from drought to recovery to full flooding, D-R-FF; from full flooding to recovery to drought, FF-R-D) were conducted. More hypertrophied lenticels, adventitious roots, and the increased stem-base hypertrophy of D. chinense were observed under the D-R-FF condition compared with FF and FF-R-D. Interestingly, the increase of the net photosynthetic rate (Pn) coincidentally occurred with the increase of heme degradation by heme oxygenase (r = 0.608, p = 0.003). Pn of D. chinense in D-R-FF was about twice as much as that in FF-R-D. The enhanced photosynthetic performance was functionally coupled with the adequate water supply to promote the tolerance of D. chinense to alternate drought–flooding condition compared with no any flooding condition. The accumulation of soluble sugar was highest under D, followed by FF-R-D, FF and D-R-FF, which showed that soluble sugar accumulation over the drought period could trigger the recovery growth of flooded plants in later flooding. These data provided the first insights into the tolerance mechanisms by a suite of morphological alterations and physiological adaptations, especially in the enhanced photosynthetic performance of D. chinense under alternating drought and flooding stresses. So, D. chinense could be considered as a prominent shrub species in the restoration practices of wetlands, riparian areas, and other flood-prone forests.
