“…Considering the difference in bicarbonate use by the two species of Moraceae, we can conclude that the more the plant used bicarbonate, the greater is the detrimental effect of bicarbonate. Greater bicarbonate uptake and utilization by plants may lead to a strong inhibition of saccharide metabolism and protein synthesis (Yang et al 1993, Nikolic et al 2000, Srivastava et al 1997 and/or a gradual reduction of ribulose-1,5-bisphosphate carboxylase/oxygenase (Bertamini et al 2001).…”

Excessive levels of bicarbonate adversely affect the growth and metabolism of plants. Broussonetia papyrifera (L.) Vent. and Morus alba L., belonging to family Moraceae, possess the favorable characteristics of rapid growth and adaptability to adverse environments. We examined the response of these two plant species to bicarbonate stress in terms of photosynthetic assimilation of inorganic carbon. They were exposed to 10 mM sodium bicarbonate in the culture solution for 20 days. The photosynthetic response was determined by measuring the net photosynthetic rate of the leaf, water-use efficiency, and chlorophyll fluorescence on days 10 and 20. The bicarbonate-use capacity of the plants was studied by measuring the carbonic anhydrase activity and the compositions of the stable carbon and hydrogen isotopes. The photosynthetic response to high concentration of bicarbonate varied with plant species and treatment durations. High concentrations of bicarbonate decreased the photosynthetic assimilation of inorganic carbon in the two plant species to half that in the control plants on day 10. Bicarbonate treatment did not cause any damage to the reaction centers of photosystem II in Morus alba; it, however, caused a decline in the quantum efficiency of photosystem II in B. papyrifera on day 20. Moreover, B. papyrifera had a greater bicarbonate-use capacity than M. alba because carbonic anhydrase converted bicarbonate to CO 2 and H 2 O to a greater extent in B. papyrifera. This study showed that the effect of bicarbonate on photosynthetic carbon metabolism in plants was dual. Therefore, the concentration of bicarbonate in the soil should first be considered during afforestation and ecological restoration in karst areas.

“…Plant growth in low B soil varied among crop species or even among different genotypes within the same species Jamjod 1997, 2004;Stangoulis et al 2000Stangoulis et al , 2001. The mechanisms underlying such variances remain unclear, however, according to the previous studies, it may involve the following: a superior ability to take up B from soil/medium (Yang et al 1993;Bellaloui and Brown 1998); the preferential translocation of B from root to shoot (Bellaloui and Brown 1998;Takano et al 2001), and the more efficient utilization of B within the plants (Stangoulis et al 2001;Zeng et al 2007). Thereby, it was speculated that the B efficiency mechanisms might vary among different species (Rerkasem and Jamjod 1997;Bellaloui and Brown 1998).…”

To investigate the effects of boron (B) on growth, B concentration and distribution of two navel orange cultivars, 'Newhall' (Citrus sinensis Osbeck) and 'Skagg's Bonanza' (Citrus sinensis Osbeck) grafted on the rootstock trifoliate orange [Poncirus trifoliata (L.) Raf.], B at five levels was exogenously supplied to 1-year-old grafted plants of both cultivars under greenhouse conditions. Plants were grown in sand:perlite (1:1, v/v) medium and were irrigated every 2 days with half-strength Hoagland's No. 2 nutrient solutions containing different B, 0.01, 0.05, 0.10, 0.25 and 2.50 mg l -1 (0.25 and 2.50 mg l -1 were considered as control and excess B treatment, respectively, and the other three B levels were considered as low B treatments). After treatments for 183 days, leaves (from basal, middle, upper parts of the shoots), stem of scion, stem of rootstock and root were separately sampled. Our results showed that plant growth (plant height, root volume and dry weights of various parts) was inhibited in response to low or excess B supplies in both cultivars. It was found that B concentrations in the upper leaves of both cultivars were substantially higher than those in the basal leaves when low concentrations (B0.05 mg l -1 ) of exogenous B were applied, suggesting that B was preferentially translocated to the upper-younger leaves to support their growth. Analysis of B distribution in different parts indicated that translocation of B from the root to the scion's shoots (stems and leaves of scion) may be restricted upon exposure to low B conditions. When B was inadequately supplied, growth of 'Skagg's Bonanza' was better than 'Newhall', implying that the former cultivar was more tolerant to low B status, which may be due to the higher efficiency of B translocation from the root to the scion's shoots. However, when the plants were treated with excess B (2.50 mg l -1 ), both cultivars showed a similar degree of B toxicity. The probability of scion-rootstock interactions in relation to the differential responses of growth and different efficiency of B translocation involved in the two orange cultivars following the long-term low B stress were discussed.

“…In tobacco, the Mg content remained unchanged (Pearce, Li, & Bush, 1999) and in olives, it decreased (Guardia & Alcantara, 2002), also under high concentrations of HCO 3 . Bicarbonate has also been considered the cause of Zn deficiency (Yang, Romheld, & Marschner, 1993), as observed in apple (Shahabi et al, 2005), spinach (Assimakopoulou, 2006), and watermelon (Colla et al, 2010) plants.…”

Little is known about the agronomic aspects of Mexican Sunflower (Tithonia diversifolia), in spite of its potential for multiple uses. In this study, we evaluated the effects of application rates of biofertilizer and irrigation on yield, growth, and leaf chlorophyll and nutrient content of Mexican Sunflower. In an experiment in the Brazilian semi-arid region, we used a 5 × 2 factorial arrangement, consisting of five application rates of biofertilizer (0, 40, 80, 120, and 160 m3 ha-1), with and without irrigation. The statistical design was randomized blocks with three replications. Irrigated plants of Mexican Sunflower had greater dry and fresh matter yields, greater height, and greater leaf area index and leaf contents of K, Zn, and B. However, the high concentration of bicarbonate in the irrigation water reduced the leaf contents of N, Ca, S, Fe, and Mn. The mean increase in the two cuttings obtained with the use of irrigation was 350% and 314% for fresh and dry matter, respectively. The increase in the biofertilizer application increased the leaf chlorophyll contents of irrigated plants; however, it did not result in production or nutritional gains. In regions with low availability of rainfall, irrigated cultivation of Mexican Sunflower is recommended.
