“…TSS and dry matter contents of broccoli heads of the winter-spring growing season were significantly higher than those of the summer-autumn growing season. These results are consistent with the reported influence of different cultivation times on dry matter and total sugar contents in cucumber [25]. We reason that the lower TSS in broccoli grown in the summer-autumn growing season may be a consequence of the relatively higher temperatures because high temperatures during the growing stages often decrease the accumulation of TSS [26,27].…”

“…The amount of phosphorus, magnesium, and iron is higher in broccoli heads from those grown in the summer-autumn growing season than those grown in the winter-spring growing season (Table S4). Moreover, the levels of phosphorus and iron showed significant differences in broccoli heads from the two growing seasons (Figure 3a,b), indicating that the summer-autumn growing season is preferred for the accumulation of these elements in broccoli heads, which is in line with a previous report in cucumber fruits in which it was found that different cultivation seasons contribute to mineral element accumulation [25]. Zinc and iron contents exhibited a significant difference between the 15 cm and 11 cm diameter of the broccoli heads (Figure 3d,e).…”

Broccoli is a rich source of diverse bioactive compounds, but how their contents are influenced by different growing seasons and variations in broccoli head sizes remains elusive. To address this question, we quantified sixteen known bioactive compounds and seven minerals in broccoli with varying head sizes obtained in two different growing seasons. Our results suggest that the contents of vitamin C, total phenols, carotenoids, and glucoraphanin were significantly higher in samples from the summer–autumn season, showing increases of 157.46%, 34.74%, 51.80%, and 17.78%, respectively, compared with those from the winter–spring season. Moreover, chlorogenic acid is a phenolic compound with relatively high contents among the six detected, while beta-sitosterol is the sterol with relatively high contents. Further, principal component analysis was conducted to rank the comprehensive scores of the profiles of phenolic compounds, phytosterols, and minerals, demonstrating that the broccoli samples grown during the summer–autumn season achieved the highest composite scores. Our results indicate that broccoli heads from the summer–autumn season are richer in a combination of bioactive compounds and minerals than those from the winter–spring season based on the composite score. This study extends our understanding of the nutrition profiles in broccoli and also lays the foundation for breeding broccoli varieties with improved nutrition quality.

“…total carbohydrates , phosphorus and potassium percentage. Also, Gajc-Wolska et al, (2010) indicated the effect of sowing date on the chemical composition of cucumber fruits. They detected the higher content of nitrogen and phosphorus at autumn season, where potassium percentage were increased at summer cultivation.…”

This investigation was conducted at the Experimental Farm, Fac. Tech. and Develop. (Gazala region -Zagazig), Zagazig Univ., Sharkia Governorate under open field during the two fallwinter seasons of 2015/2016 and 2016/2017, to study the effect of three cultivars of squash ( Eskandarany, Revera and Azyad) and foliar spray treatments with, yeast extract at the rate of 3 and 6gl -1 ,as well as potassium silicate at the rate of 2 and 4gl -1 plus control (tap water)and their interactions on flowering expression, i.e., number of male and female flowers plant -1 , sex ratio and femalness percentage, yield and its components (number of fruits plant -1 , fruit fresh weight, and dry matter percentage, total fruit yield plot -1 and relative yield), as well as fruit quality, i.e., fruit physical characters (both of fruit length and diameter) and fruit chemical composition (nitrogen, phosphorus and potassium content, protein and total carbohydrates percentage). Results showed the superiority of the two tested cultivars Azyad and Revera at all studied characteristics compared with Eskandarany cv. Spraying with yeast extract or potassium silicate significantly increased most parameters of flowering, fruit yield and quality attributes of squash than control treatment . Moreover, spraying plants with potassium silicate at rate of 4gl -1 or yeast extract at 6gl -1 significantly surpassed compared with the other foliar treatments and control in this respect. The best results of the interaction treatments for flowering, yield and fruit parameters were recorded by the two cultivars Azyad or Revera combined with the foliar 434 SALAMA et al.spray by 4gl -1 of potassium silicate or 6gl -1 of yeast extract which recorded increased in most of all the mentioned studied parameters.Hence, each of these treatments could be recommended for enhancement flowering, yield and fruit quality of squash plants with low cost production when planted in open field at fallwinter season under the same conditions of this experiment.

“…There is evidence from a few recent studies that insect pollination may not only benefit crop yield but also influence the shelf life of agricultural products. Greater firmness of insect-pollinated tomato [12], oriental melon [13], cucumber [14] and strawberry [15] only indirectly indicates possible effects of insect pollination on shelf life. Pollinator-enhanced shelf life could be an important solution to reduce postharvest losses, but data proving a direct relationship between insect pollination and shelf life are still lacking.…”

Enhancing crop shelf life with pollination

Background: Globally, high amounts of food are wasted due to insufficient quality and decay. Although pollination has been shown to increase crop quality, a possible impact on shelf life has not been quantitatively studied. Results: We tested how shelf life, represented by fruit decay, firmness and weight, changes as a function of pollination limitation in two European, commercially important strawberry varieties. Pollination limitation resulted in lower amounts of deformed fruits. Whereas 65% of wind-pollinated fruits were deformed, open pollination resulted in only 20% deformed fruits. During storage, the proportion of decayed fruits increased in relation to the degree of deformation. In the variety Yamaska, 80% of the fruits with high degrees of deformation decayed after four days, whereas in the variety Sonata, all highly deformed fruits had already decayed after three days. Fruit weight decreased independent from the degree of deformation. However, strongest deformations resulted in a generally lower fruit weight in Sonata, whereas in Yamaska, also medium deformed fruits had a lower weight than highly deformed fruits. Effects of deformation on firmness declines were mostly variety dependent. Whereas firmness declined similarly for all degrees of deformation for Yamaska, highly deformed fruits lost firmness fastest in Sonata.
