“…The combination of cultivar and sun exposure showed no clear impact of radiation level for the two years. This is in accordance with a study on colored shading nets for H. macrophylla, where no significant effects on plant height (cm) and LAI from cultivation under black, red and blue shading were found for most of the cultivars tested [51]. For 'Amagi Amacha', full shade conditions seem optimal for higher biomass; for 'Oamacha' and 'Odoriko Amacha', no clear advice has been given.…”

Dihydroisocoumarin Content and Phenotyping of Hydrangea macrophylla subsp. serrata Cultivars under Different Shading Regimes

Hortensias (Hydrangea macrophylla L.) are well known as ornamental plants with their impressive flowers. Besides being an ornamental plant, some hortensia species contain constituents of nutritional and pharmaceutical interest. In this context, H. macrophylla subsp. serrata contains dihydroisocoumarins (DHCs), in particular hydrangenol (HG) and phyllodulcin (PD), which determine produce quality. For the successful cultivation of H. macrophylla subsp. serrata, shading may be required. The response of H. macrophylla subsp. serrata as a source for DHCs was investigated in two growing seasons using three different cultivars (‘Amagi Amacha’, ‘Oamacha’ and ‘Odoriko Amacha’) under three different light conditions: no shade (100% photosynthetic active radiation, PAR), partial (72% PAR) and full shading (36% PAR). The shading regimes had no significant effect on dihydroisocoumarin content in leaf dry matter in each single cultivar. However, ‘Amagi Amacha’ and ‘Oamacha’ yielded significantly higher PD content in comparison to ‘Odoriko Amacha’, which showed, in contrast, the significantly highest HG content. The total biomass was not significantly affected by the shading regime, but slightly higher biomass was observed under partially shaded and full-shade conditions. Hyperspectral vegetation indices (VIs) and color measurements indicate less vital plants under no shade conditions. While lighting is an important growth factor for hortensia production, DHC is cultivar dependent.

“…A similar type of result was observed by Stamps and Chandler (2008) in Aspidistra elatior under black shade net. Nesi et al (2013) also found highest plant height in Hydrangea macrophylla var. Dienemann and Tricolor under black shade net.…”

The investigations were carried out during 2016–17 and 2017–18 under three different coloured shade nets (white, green and red) along with the controlled environment (open condition) at Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India to study the production behavior of Asparagus plumosus, India. The experiments were arranged in Complete Randomized Design (CRD) with four replications and maintained in pots. Similar management practices were followed for all the treatments throughout the growing period. The pooled data of two years revealed that plants grown under the green shade net showed significant improvement in all the vegetative parameters i.e. plant height (109.6 cm), plant spread (70.67 cm), leaf length (33.35 cm), leaf breadth (22.00 cm) and petiole girth (0.80 cm), whereas lowest data observed in the plants maintained without any shade net. The leaf production was also better in the plants raised under green shade net than other treatments. The highest number of leaves per plant and leaf longevity was found in green shade net treatment. The leaf production interval was remarkably lowest in the plants grown under green shade net. The leaf quality was better under green shade net in terms of colour intensity, vase life and chlorophyll content. The green shade net gave overall better performance regarding both physiological and quality parameters and can be suitable for commercial cultivation.
