“…The application of the tested products could be a practice for overcoming and/or containing moderate stressful conditions, which affect photosynthesis (e.g. Flexas et al, 2004, Lieth and Pasian, 1991and Yamori et al, 2005, with positive effects on production sustainability and market competition (e.g. shorter cultivation cycle).…”

Highlights•Fermented organic materials and their hydrolysates were tested on substrate-grown Hibiscus.•Positive effects were observed on total biomass, plant height, SPAD index and net photosynthesis compared with untreated plants.•Tested products performed at the same level of a commercial product.•Obtained results represent a step forward for the application of biowaste hydrolysates in intensive substrate cultures. AbstractTwo urban biowaste materials, fermented under anaerobic and aerobic conditions, their soluble and insoluble alkaline hydrolysates, and a commercial biostimulant product, were compared for their capacity to boost Hibiscus crop production and quality. Plants were grown in 4-litre pots, containing peat and pumice as substrate, under optimal growing conditions. A randomized-block experimental design was adopted. Two types (main factors of variability) of treatments were applied, i.e. by blending the above products with the substrate at transplant, and by fertigation using the soluble hydrolysates only. Plant biomass characteristics and ecophysiological parameters were measured. Mean effect of factors and their interactions were assessed by two-way ANOVA. Principal component analysis was performed by using the different dependent variables to summarize the most relevant differences among treatments. Compared with the control (untreated plants), the applied treatments enhanced most of the investigated parameters. The most valuable effects were observed for total biomass accumulation (+25%), plant height (+10%), leaf chlorophyll SPAD index (+15%) and net photosynthesis (+24%). The hydrolysates performed better than the pristine materials. The former ones were comparable to the commercial biostimulant. The results confirmed the hypothesis that biowaste derived products induce biostimulant activity on Hibiscus; their application can improve cultivation sustainability. ); SD, soluble digestate hydrolysate obtained from the alkaline hydrolysis of D; SGC, soluble compost hydrolysate obtained from the alkaline hydrolysis of GC; SUB, treatments applied to the substrate as a powder blended with the substrate; T 1 , beginning of the experimentation (30 days after transplant) (day)

“…The conservative growth pattern of the rose BS is particularly important for several reasons: during the long growing season of the rose crop, radiation and temperature vary considerably, because growers control them separately, which weakens possible correlations between them, and modifies their natural seasonal trends [42]. The sizes and ages of the flowering shoots in the stand are mixed, which prevents the definition of a 'typical' flower [17].…”

“…The idea of the template follows the method of the "observed pattern" of Lieth and his collaborators [17,18] and the "module" and "paracladium" concepts in the L-system [2,23]. In ROSGRO, these templates derive from measurements made on basal shoots (BSs), a particular type of shoot that occurs rarely and reaches exceptionally large dimensions [24].…”

Abstract. The objective of this study was to describe and analyze the effect of high pressure sodium lamp lighting (HPS) on dynamics of growth and dry matter partitioning, and light use efficiency of sweet pepper crop grown over winter season. Young sweet pepper seedlings were planted at 3.75 plants per m 2 on September 29, 2010 and treated with HPS for 16 hours from December 14, 2010 until March 18, 2011. The number of leaves per plant were significantly increased with HPS, whereas the number of internodes and leaf area were less affected. HPS reduced the plant height with higher number of fruits per stem compared to those of without HPS lighting (CON). There were large differences in total dry mass production, stem and fruit dry mass between HPS and CON and those with HPS increased by 67.8%, 28.5%, and 97.1% compared to CON, respectively. Each organs of dry mass partitioning was calculated by leaf, stem or fruit growth rate divided by total plant growth rate. Dynamics of dry mass partitioning to leaf and stem between HPC and CON was measured in range of 45-47% at beginning of growth phase and drastically decreased after starting fruit growth in both treatments. Dry matter partitioning to vegetative organs was 4% higher compared to the plant grown under HPS lighting. Averaged dry matter partitioning to fruit with HPS, however, was largely increased by 14.2% compared to CON. Dynamics of the plant growth were well described by expolinear growth equation with three parameters of maximum relative growth rate, absolute growth rate and lost time to reach linear phase. The maximum growth rate of leaf, stem and fruit with HPS was increased by 18.6%, 74.7%, and 143.5% compared to CON. There was a linear relationship between intercepted light integral and vegetative organs (leaf and stem), fruit or total dry mass production. Light use efficiency (LUE, g･MJ -1 ) of total dry mass was 4.90 g･MJ -1 for HPS and 3.84 g･MJ -1 for CON, LUE of vegetative organs was 1.56 g･MJ -1 for HPS and 1.61 g･MJ -1 for CON and LUE of fruit dry mass was 3.34 g･MJ -1 for HPS and 2.23 g･MJ -1 for CON. The difference in LUE of total dry mass between treatments, therefore, occurred mainly from the different in LUE of fruit dry mass.Additional key words: dry matter partitioning, expolinear, light use efficiency
