“…However, LRWC of dwarf bamboo returned back to the control level after 15 days of rewatering (Fig. 1), which was consistent with previously published studies in other plant species (Cai et al 2005;Miyashita et al 2005;Bian and Jiang 2009). This indicates that dwarf bamboo seems to be capable of withstanding and surviving extreme drought events.…”

Key message Differential regulations of C and N metabolism in dwarf bamboo improve the capacity of osmotic adjustment, and also their metabolites may play an important role for protection against membrane lipid peroxidation under drought, thus accelerating recovery after rewatering. Abstract Dwarf bamboo (Fargesia rufa Yi), is a staple food for the endangered giant panda, but little is known about the impact of drought on bamboo species and its recovery mechanism. This study investigated the response of carbon (C) and nitrogen (N) metabolism to drought and subsequent recovery, and the relationship of their metabolites with lipid peroxidation. Photochemistry was reversibly down-regulated after drought, but a longer recovery time is needed. The accelerated degradation of starch due to a rapid increase in amylase activity resulted in higher soluble sugar only in severe drought-stressed plants after 30 days of drought. Sucrose content was not affected by drought because of the relative increases in activities of invertase, sucrose synthase, and sucrose phosphate synthase. As nitrate concentration increased in parallel with nitrate reductase activity, ammonium (NH 4 ? ) production was enhanced by drought. Also, activated glutamine synthetase/glutamate synthase cycle stimulated NH 4? assimilation, while hydrolysis of soluble proteins was accelerated, resulting in accumulation of amino acids. After rewatering, re-balancing of C metabolism has gradually begun, but a stronger N metabolism was still observed. The notable positive correlations between MDA and the contents of starch and proline after 15 days of drought as well as between MDA and the contents of soluble sugar, NSC and proline after 30 days of drought were displayed. We conclude that dwarf bamboo may not only differently regulate its C and N metabolism to improve the capacity of osmotic adjustment but also employ its different metabolites protect against membrane Communicated by M.

“…Drought directly and indirectly impacts photosynthesis, which is one of the primary metabolic processes influencing plant growth and development (Pieters & El Souki, 2005;Praxedes et al, 2006). Miyashita et al (2005) reported similar recovery process to the present study in kidney beans (Phaseolus vulgaris) after forty-eight hours of re-watering in plants grown under drought stress.…”

“…The negative impact of the drought on photosynthetic rate has been well documented in the literature (Miyashita et al, 2005). However, photosynthetic response to the repeated cycle of drought and re-watering is varied among plant species and between different varieties within the same species (Izanloo et al, 2008;Xu et al, 2010).The variation response in photosynthesis is due to different adaptive mechanisms involving conferring drought tolerance ).…”

“…Several studies have examined some aspect of plant physiological response recovery to drought with varying results (Subramanian & Maheswari, 1990;Heckathorn et al, 1997;Widodo et al, 2003). Miyashita et al (2005) found that photosynthesis was most rapid phenomena in the recovery process after water stress relief in kidney beans (Phaseolus vulgaris) and this was followed by stomatal conductance. However, the recovery level of photosynthesis, transpiration and stomatal conductance were below half compared to the control when the drought was extended from three to seven days.…”

This greenhouse study was carried out to determine the impact of drought on plant growth, photosynthetic rate and the recovery of photosynthesis after drought relief. Twenty four Roselle plants were equally divided between the control and the treatment groups, which received 100% and 25% soil saturation respectively. The plants were grown under greenhouse conditions with the temperature averaging 27 ± 2ºC. The treatments were applied with seven cycles of watering until the plants reached the anthesis stage. The drought influence caused a significant reduction in the plant height, flower number, and photosynthetic rate. Re-watering the plants growing under drought to 100% water saturation resulted in complete recovery of photosynthetic rate within forty-eight hours. However, rewatering to 25% showed only 30% recovery in photosynthetic rate after forty-eight hours. Photosynthetic pigments including chlorophyll a, b and carotenoid were not significantly influenced by the drought. Similarly, total phenolic compound concentration of the calyx was insignificant between the treatments. However, Anthocyanin concentration of the calyx was significantly higher under the drought treatment.

“…The slower recovery of the plants in unamended soil and with mulched compost could be due to the smaller root system as well as the longer drought period. Miyashita et al (2005) found that the level of the recovery of kidney bean was decreased as the drying period became longer.…”

Compost can increase soil water availability and nutrient uptake by plants, but it is not clear whether it can also improve the ability of plants to recover after drought stress. Tomato plants (Lycopersicon esculentum L.) were grown in sandy soil without compost or with compost either incorporated or mulched. There were two water treatments: (i) plants grown under sufficient water supply throughout the experiment and (ii) plants grown with sufficient water supply until day 33 after which water was withheld until stomatal conductance was close to zero. Compost addition increased water content at both field capacity and permanent wilting point, but only incorporated compost increased total available water. Compost addition increased shoot and root growth under well-watered and drought stressed conditions with a greater effect by incorporated compost. At sufficient water supply, the rates of photosynthesis and transpiration were similar in all treatments. Drought stressed plants with incorporated compost wilted earlier than control plants, whereas mulched compost increased water availability to plants and hence the number of days until wilting. Photosynthesis and transpiration recovered faster in plants grown with incorporated compost compared to other treatments. The rapid recovery of plants after drought with incorporated compost could be due to their greater root length.
