摘要:
Changes in protein synthesis in leaf tissue of six cotton cultivars were studied by comparing the heat-shock protein patterns synthesized at different heat treatments. Leaf tissue responded to thermotolerance treatments by synthesizing a specific set of proteins for each treatment and cultivar, which differed from profiles observed with a direct shift to high temperatures. We found minor differences in the heat-shock proteins profile observed in the prolonged heat treatment when compared with the direct-shift treatment profiles. Newly synthesized proteins of 35 kDa, 37 kDa and 23 kDa were found respectively in Delta Pine Acala 90, Acala 1517–70 and Selati. The late heat-shock protein profiles differed from patterns found with thermotolerance.

摘要:
The streak disease-resistant Vaalharts maize composite was used as the non-recurrent parent in crosses with the USA inbred lines Mo17 and B73, and local elite breeding material, representative of the F and M heterotic groups, to develop resistant inbred lines with improved combining ability for yield. S3 lines were crossed to I137TN as tester. Compared with prominent commercial hybrids, a number of test crosses were identified with superior yield potential under streak conditions and comparative yields in the absence of the disease. Characterization data on 15 S5 lines, intended for release, are provided.

摘要:
The impact of various weeding and site-preparation treatments onAcacia mearnsiiandPinus patuladamage by mammalian pests was assessed. Browsing by small antelope onAcacia mearnsiiwas significantly less in areas where harvesting residues had been retained rather than burned. There was significantly less browsing in weedy areas than in weed-free areas. Rodent damage onPinus patulaincreased exponentially with increasing weediness.
