Introduction:

In recent years, it has been demonstrated that numerous crops have increased their productivity and fruit quality when grown under a color-selective shade net (1).

Red shade nets, developed in the last decade to filter specific regions of the solar spectrum and induce light dispersion, aim to optimize desirable physiological responses and provide physical protection to crops (2).

In 2008, red bell pepper plants (Capsicum annuum L.), varieties ‘Vergasa’ and ‘Romans,’ were cultivated at the B’sor Experimental Station in the Southwest of Israel, employing commercial cultivation practices under four different colored shade nets: sand, red, yellow, and black with 35% relative shading (in PAR).

Fruits were harvested weekly at 80-85% red maturity, using a calyx-free cutting tool. Cumulative total yield and export-quality harvest were evaluated from early September to early December. Fruits with export quality are defined as those weighing above 130 g each (average and larger dimensions) without defects. The quality of the harvest under red shade nets was assessed four times during fruit growth phases. The parameter of deterioration incidence related to fruit quality was examined immediately after each harvest and after 14 days of storage at 7°C with ~94% relative humidity (RH), as well as 3 days at 20°C.

Sand, red, or yellow shade nets positively affect crops compared to black shade nets.

Yield and Export Quality:

Results showed a significant increase in the total harvest quantity under the color-selective shade net. For the ‘Vergasa’ variety, the red and sand nets increased the harvest by 30%, 32%, and 34%, respectively, compared to the commercial black net. Regarding the ‘Romans’ variety, the red, yellow, and sand nets increased the harvest by 6%, 16%, and 14%, respectively, compared to the black commercial net. The export-quality fruit yield was more affected. In this case, the relative increase due to the red, yellow, and sand nets was 39%, 56%, and 56%, respectively, for the ‘Vergasa’ variety, and for ‘Romans,’ the export-quality fruit production increased by 2%, 34%, and 18% under the red, yellow, and sand shade nets, respectively.

The color-selective shade net influences the total harvest quantity.

Post-Harvest Quality:

In preliminary experiments conducted in 2007, results showed that harvests from yellow and red nets had significantly lower decomposition incidence after extended storage (3).

At the end of the simulated storage lifespan, the product grown and harvested under the sand-colored shade net had significantly lower decomposition incidence compared to the harvest under the commercial black shade net.

Fruits collected under the yellow net also had a relatively low decomposition rate compared to the commercial black net.

CONCLUSIONS:

We have demonstrated the potential use of red, sand, and yellow shade nets to increase bell pepper productivity compared to the traditional black net and maintain higher fruit quality after prolonged storage periods. The significantly lower incidence at the end of the simulated storage lifespan is the most interesting result. How can stored fruit “remember” its light conditions during growth? There are explanations for the effects of light quality during plant development that are currently hypothetical at this stage: (i) light quality directly affects the spread of pathogens in the field, manifesting later in the postharvest; (ii) Photoselective effects on fruit characteristics have been related to the infective capacity of pathogenic fungi, such as fruit subsidence or cuticle morphology, or other defense processes; (iii) An indirect photoselective effect on host plant susceptibility, which could then affect storage life.
