In the current scenario of climate change, sorghum crop has high growth potential, requiring adaptation and selection studies for the various Brazilian production environments. Sorghum is among the most drought-tolerant cereals; however, extended summer can reduce the size and number of grains in the plant, reflecting into poorer yields. Sorghum breeding programs aim to develop hybrids more tolerant to water deficit, to ensure profitable yield even in the face of drought stress. The objective of the present study was to evaluate the effects of water restriction on grain sorghum hybrids in the pre- and post-flowering phases in the Brazilian semiarid. Twenty-five hybrids were evaluated under controlled irrigation conditions in Nova Porteirinha-MG and Teresina-PI. In the Nova Porteirinha, the hybrids were cultivated under conditions of non-drought stress and with drought stress in pre- and post-flowering stage. On the other hand, in Teresina, the experiment took place with non-drought stress and drought stress at post-flowering stage. The experimental design was in randomized complete blocks, in factorial scheme, with three replications. Drought stress reduced grain yield by more than 40%, showing that even being resistant, sorghum is affected by drought. Hybrids 1168093, 1167092, 1236020 and 1423007 showed high yields in the various environments, outyielding the commercial controls, what allows the recommendation of these cultivars for the semiarid areas or late off-season in the Cerrado region.

Psidium acutangulum demonstrated promising results from its extracts for some biological activities, which may favor its use as herbal medicine. However, there is still a lack of research that identifies the chemical components of its essential oil. The present study aimed to evaluate the influence of climatic factors on the yield and the chemical composition of essential oils from the leaves and fruits of P. acutangulum. One specimen was monitored for one year with monthly collections. The essential oils were obtained by hydrodistillation, and the chemical composition was analyzed by gas chromatography coupled to mass spectrometry. Chemometric analyzes were performed to verify climatic influences on yields and the chemical composition of P. acutangulum oils. The average oil yields in the dry season (June/February, 0.7 ± 0.3%) and the rainy season (March/May, 0.9 ± 0.2%) did not show a statistical difference. There was a moderate negative correlation between oil yield and insolation (r = 0.53). The predominant class of EOs for seasonal (S) and fruits (F) were oxygenated sesquiterpenes (S: 27.9?85.0%; F: 15.5%), followed by sesquiterpene hydrocarbons (S: 5.5?46.2%; F: 51.0%) and monoterpene hydrocarbons (S:1.8?16.3%; F: 13.6%). The constituents with the highest content in the EOs of P. acutangulum were caryophyllene oxide (0.0?75.1%, 42.4 ± 18.2%), α-pinene (1.5?12.7%, 6.5 ± 3.7%), and α-cadinol (0.0?11.9%, 5.7 ± 2.2%) in leaves, and for the fruits were E-caryophyllene (21.6%) and α-cadinol (5.1%). Climatic parameters can be correlated with caryophyllene oxide and E-caryophyllene amounts, but not with α-cadinol and α-pinene. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) showed no separation between the oil samples of P. acutangulum during the dry and rainy periods. However, correlations were observed between the oils? constituents and the environmental parameters. There is great seasonal variability in P. acutangulum. Prior chemical knowledge must be available before suggesting its use.
