“…The significant augmentation of dimensions of generative shoots might be result of growing ground moisture. The positive relationship among soil humidity and number and dimensions of shoots, flowers and inflorescences was observed in Gladiolus grandiflorus (Porto et al 2014;Pereira et al 2016aPereira et al , 2016b. The reducing flowering of Gladiolus individuals in effect of decrease of soil moisture was also observed by Shillo and Halevy (1976).…”

Abstract. The investigations, aimed to assess the abundance, stage structure and distribution of shoots, as well as the chosen traits of generative shoots (number of leaves and length of the longest one, height of shoot, length of inflorescence and the dorsal tepal of the lowermost flower, number of seed capsules) of Gladiolus imbricatus L. were conducted in the years 2015-2017. The observations were carried out from Kraków-Pychowice to Tyniec in abandoned moor-grass meadow (Patch I), shrub willows (Patch II), macroforb community (Patch III) and community dominated by tall-growing grasses (Patch IV). The population abundance augmented gradually in subsequent study sites. Additionally, the temporal fluctuations of shoot number were recorded in all the Patches. The similar in consecutive years' stage structure differs among the study sites. The occurrence of juvenile, vegetative and generative shoots in Patch I might suggest the successful seedling recruitment, while the lack of shoots in pregenerative stages in Patches II-IV might indicate the absence of safe sites for the appearance of new genets. The occurrence of clusters of shoots in Patches II-IV might be a consequence of clonal growth. The traits of generative shoots rather did not show the temporal variability, but they presented spatial variability and in most cases augmented from Patch I, via Patches II and III, to Patch IV.The performed studies enabled ascertaining that the population occurring in Patch I presents the best condition despite the lowest abundance of shoots. Also the other, more abundant populations, inhabiting Patches II-IV might persist in the colonised sites thanks to the vegetative multiplication of ramets and maximisation of chances for successful pollination and effective seed dissemination.

“…In the literature, however, there are divergences on recommended irrigation for gladiolus, as Porto et al (2014) found optimum soil water content at 134.41% FC for the same cultivar, and obtained much longer flower stems reaching up to 137.60 cm at harvest time. On the other hand, Pereira et al (2009) observed that FC close to 100% resulted in longer gladiolus flower stems with more flowers; the latter studied a medium maturity cultivar that might present different responses than early maturity ones.…”

“…According to Porto et al (2014), the appropriate water content, obtained in this study by 81% FC, promoted greater assimilation of carbohydrates by the plant, which is used as an important component of photosynthesis, resulting then in increased development what was demonstrated by plant height and leaf number. From 81% FC, thus increase in soil water content, values of both variables started to decrease.…”

Gladiolus grandiflorus Andrews, in the family Iridaceae, is one of the most produced and marketed flowers in the world. In general, however, research results on gladioli production factors are scarce and divergent. The objective of this work was to evaluate the influence of corm size and soil water content on gladiolus flower production. The experimental design, using the early maturity cultivar 'White Friendship', was entirely randomized, arranged in a 5 x 2 factorial scheme (five soil water contents: 25; 50; 75; 100; and 125% field capacity, combined with two corm sizes: medium and big), with four replications per treatment. Each replication, composed of one pot, comprised three corms, totaling 40 pots and 120 plants. Both vegetative and flowering characteristics were evaluated. Gladiolus cultivation at 80% soil field capacity presents best results for commercialization, generating longer flower stems with greater diameter and flower number, plus larger flowers. Furthermore, such soil water content promotes the shortest cultivation period.

“…Numerous studies have examined the morphological and physiological responses of C. bungei to water stress and nitrogen fertiliser application , but the interactive effects of these two factors on the growth, photosynthetic productivity, and WUE of C. bungei seedlings have rarely been studied. Previous investigations have emphasised problematic issues surrounding water and fertiliser use; both resources are often supplied at excessive rates (Pires & Xavier, 2010;Porto et al, 2014). Catalpa bungei plantations have expanded rapidly, especially in arid areas of China, and the massive use of water and fertiliser has become an issue of considerable controversy.…”

“…Soil water and nutrients are key limiting factors for plant growth; they have marked effects on physiological characteristics, growth, and productivity (Dong et al, 2011;Liu et al, 2013;Porto et al, 2014). In general, leaf functional traits and physiological characteristics, which are strongly influenced by environmental factors, provide key information on plant growth and metabolic status.…”

Interactions between soil water and fertilizer on leaf photosynthesis and δ13C of Catalpa bungei seedlings

et al. 2016

Abstract:Our objective was to identify combinations of irrigation and fertiliser application that promoted the photosynthetic productivity and water use efficiency (WUE) of Catalpa bungei. Using response surface methodology based on a rotatable central composite design, we conducted a pot experiment with C. bungei clone 004-1 seedlings. The experiment quantified the effects of interactions between soil water content (W), nitrogen application rate (N), and phosphorus application rate (P) on leaf net photosynthetic rates (Pn), SPAD values (SPAD-502 meter readings of leaf chlorophyll), and carbon isotope composition (δ 13 C). N had significantly positive effects on the all three leaf parameters, while W had significantly negative effects on leaf δ 13 C signatures but positive effects on leaf Pn and SPAD values. The magnitude of the N effect exceeded that of the W effect. P had no significant effects on any of the three leaf parameters. The W × N interaction had significant positive effects on Pn and SPAD, but significant negative effects on leaf δ 13 C. Thus, irrigation and nitrogen application had different effects on seedling growth and WUE, and the two effects were interactive. Catalpa bungei growth was promoted by appropriately increasing nitrogen application and irrigation, but WUE was improved by increasing N and decreasing irrigation. Therefore, strategies for the irrigation and fertilisation of C. bungei plantations should be designed to appropriately balance plant growth and WUE.
