Effect of Grafting on the Cucumber Yield and Quality Under High and Low Temperatures.

Abstract

Two experiments were conducted during the summer and winter seasons of 2013 to study the effect of grafting using different rootstocks on the yield and quality and chemical analysis of cucumber (Cucumis sativus L.) cultivar "Hady" under high and low temperatures. The experiments consisted of 5 treatments, 4 rootstocks, namely Bottle Gourd (Lagenaria siceraria Standl.), Supper Shintosa (Cucurbita maxima Duchesne×Cucurbita moschata Duchesne), Squash 3 (Cucurbita pepo) and Ferro' (C. maxima × C. moschata), in addition to non-grafted control. Data were recorded on plant length and physical characters of fruits 30, 60 and 90 days after planting, early and total yield/m2, chemical characters (percentage of dry matter, TSS and total and reducing sugars) of cucumber fruits and percentage of N, P and K in cucumber leaves. The results indicated that Ferro rootstock increased plant height, physical characters, early and total yield of cucumber fruits in both summer and winter seasons, as compared with non-grafted control. No significant effect was detected from using rootstocks on N, P and K percentage in cucumber leaves, except grafting cucumber on Bottle Gourd rootstock which significantly increased N% only in the winter season. Chemical contents of cucumber fruits were not affected by grafting in summer season, while Bottle Gourd increased total sugars and Ferro rootstock caused significant increase in the percentage of dry matter and reducing sugars in winter season as compared with non grafted plants.

Effect of Grafting onto Different Rootstocks and some Foliar Applications on Cucumber Production under High Polyethylene Tunnel Conditions.

“…In this concern, many authors proved that grafting affected fruit yield of cucumber Mady (2009). Besides, El-Sayed et al, (2014) who stated that grafting increased early and total yield of cucumber fruits. Also, these results are supported by the findings of Barnett et al (1990).…”

Utilizing of Different Cucurbit Rootstocks as a Sustainable Alternative to Enhance Growth, Productivity and Fruit Quality of Cucumber

“…Pumpkin rootstock PI599586 in both years exhibited the highest significant TSS%. Several former studies recorded increment in average fruit weight trait (El-Sayed et al, 2014…”

The Effect of Grafting on Squash Plants Grown Under Low Plastic Tunnel in Winter Season

“…Owing to using genetically different rootstocks all the studied characteristics were significantly affected by type of rootstocks used for grafting. El-Sayed et al (2014) who indicated that the effect of grafting using different rootstocks on cucumber (Cucumis sativus L.) cultivar "Hady" in winter season caused a significant increase in plant height over self-grafted control plants. The results indicated that Ferro rootstock increased plant heightof cucumber in summer and winter seasons as compared with un-grafted control.…”

“…Grafting of cucumber on four different rootstocks namely Bottle Gourd (Lagenaria siceraria Standl. ), Supper Shintosa (Cucurbita maxima Duchesne×Cucurbita moschata Duchesne), Squash 3 (Cucurbita pepo) and Ferro (C. maxima × C. moschata) resulted in an increase in cucumber plant height when grafted on Ferro rootstock in both summer and winter seasons, compared with (control) and other rootstocks used (El-Sayed et al, 2014).Rootstocks considered as powerful of supply water and nutrient uptake by the soil leads to distribute growth regulators to the grafted parts (Helaly, 2017).
