“…An extreme variability of yields is registered in this experimentation, in accordance with also other studies, where different hybrids studied in different agro-climatic conditions gave yields ranging from 1 t ha −1 to 4 t ha −1 (Champolivier et al, 2011;Mohammadi et al, 2013;Sezen et al, 2011).…”

“…Likewise, stem diameter had the same trend for such trait in both seasons. These results are in harmony with those reported by Mohammadi et al (2013). Besides, data presented in Table (2) showed that number of days to 50% flowering gradually decreased as a result of increasing irrigation interval from 12 to 24 days.…”

Growth expressions of sunflower, supplied with 30, 45, and 60 kg N/ fad, were examined under the treatment of two tillage practices (conventional tillage and no tillage applications) and three irrigation intervals (12, 18 and 24 days, between each two successive irrigations) during 2017 and 2018 summer seasons at the Experimental Farm of the Itay-EL-Baroud Agricultural Research Station. Responses of plant height, leaf area index, flowering date, stem diameter, head diameter, 1000-seed weight, seed yield/ fad., harvest index and seed oil content in addition to oil yield/ fad. were significant having the maximum records for sunflower with 12 days interval of irrigation. Also, the highest values of plant height, leaf area index, harvest index, seed yield/ plant, during the two seasons, and seed yield /fad, oil yield (in 2017) and 1000-seed weight (in 2018) were achieved with conventional tillage compared to no tillage. Meanwhile, no significant effects were obtained for flowering date, stem diameter and head diameter during the two seasons of study, and 1000-seed weight (in 2017), seed yield and oil yield/ fad (in 2018) based on tillage practice. Increasing the level of nitrogen fertilization up to 60 kg/ fad, significantly increased all studied characters except nitrogen use efficiency (NUE) and oil percent which decreased with increasing nitrogen levels during the two seasons. The interaction of irrigation intervals and tillage practice significantly affected plant height over the two seasons. This trait had maximum values with the shortest irrigation interval (every 12 days) and 60 kg N/ fad. The obtained data indicated that 1000-seed weight, seed yield/plant, leaf area index and harvest index were significantly affected by the irrigation interval and nitrogen levels interaction. Meanwhile, high seed and oil yields were achieved with short interval (every 12 days) under conventional tillage and nitrogen levels of 40 and 60 kg N/ fad. It is recommended to grow sunflower under conventional tillage practice, with applying irrigation every 12 to 18 days and nitrogen fertilizer at the rate of 45 to 60 kg N/ fad, to obtain highest seed and oil yields.

“…Genetic factors, abiotic factors such as environmental factors and soil conditions, and their interaction are known to affect the fatty acid composition of plant seed oils [23][24][25][26][27]. In this research, S. mukorossi seed oil-related variables including 100-seed weight, 100-kernel weight, and 100-oil weight were significantly negatively correlated with annual maximum temperature and annual precipitation.…”

Sapindus mukorossi is widely distributed in tropical and subtropical areas of southern China; the seed kernel oil is potential biodiesel material, and the saponins extracted from fruit pericarp are very valuable efficient natural surfactants. Therefore, S. mukorossi is an ideal tree species for developing forestry bioenergy and multiple other products. In this study, 42 S. mukorossi fruits from mother trees were collected from 39 distinct locations in 12 Chinese provinces to infer fruit and seed trait responses to environmental factors. Canonical correspondence analysis (CCA) was conducted using 21 horticultural fruit traits and 10 environmental factors that represented different climatic and geographic conditions throughout southern China. CCA revealed well-developed patterns of natural phenotypic variation, and insight into the ecological factors that are potentially important in shaping this variation. The results presented here further elucidate the natural distribution and ecological adaptations of wild S. mukorossi resources, which will be valuable for S. mukorossi cultivation by helping identify ideal planting areas. The germplasm resources with extensive morphological variation can also contribute to S. mukorossi breeding in the future by helping develop new cultivars with high saponin yield.
