  Cowpea [ Vigna unguiculata (L.) Walp] is a multipurpose crop that provides nutrients for human and livestock diets, as well as regulates and supports ecosystem services. In developing countries, cowpea is exploited as a dual-purpose crop for its grain and fodder; it is cultivated primarily for grain and as a cover crop in industrialized countries. However, root-knot nematodes (RKNs) ( Meloidogyne spp.) represent a threat to cowpea production worldwide. Thus, we screened the University of California, Riverside (UC-Riverside), cowpea mini-core collection for resistance to Meloidogyne incognita Kofoid and White (Chitwood) and M. enterolobii Yang and Eisenback to verify the potential of this collection to be used for improving RKN resistance in cowpeas. Both screenings showed significant genotypic variation and medium/high broad-sense heritability ( H 2 ) estimates for most traits, and several traits were also strongly correlated. For the M. incognita screening, 86.1% of accessions showed some level of resistance based on gall score (≤3), and 77.7% based on reproduction index (RI) (25 ≤ RI ≤ 50), whereas only 10.4% and 29.8% of accessions were resistant to M. enterolobii based on gall score (≤3) and RI (25 ≤ RI ≤ 50), respectively. These results demonstrate the greater virulence of M. enterolobii than M. incognita in cowpea, and that geographic origin of germplasm was not linked to sources of resistance. Among cultivars, only US-1136 showed resistance against both nematode species, whereas 12 wild/landrace germplasms exhibited resistance to M. incognita and M. enterolobii , and can be exploited for breeding resistant cowpeas.

  In Florida, early planting to take advantage of higher prices for early fruit has been proposed for the strawberry (Fragaria ×ananassa Duch.) industry, but it can expose strawberry transplants to heat stress which is common in sub-tropical conditions. Additionally, strawberry plug transplants are of interest for addressing the high sprinkler irrigation requirement for bare-root transplant establishment. The objective of this study was to examine the effectiveness of antitranspirants, s-abscisic acid (s-ABA) and kaolin, in heat stress mitigation for strawberry plug transplants. Trials were conducted in Citra, Florida during three seasons (2015–2016, 2016–2017, and 2017–2018). The s-ABA was applied as a root dip just prior to transplanting. In 2015–2016, s-ABA was applied at 250, 500, 750, and 1000 mg L−1. Lower rates of 50–250 mg L−1 were used during the subsequent years. Kaolin was applied at 56 kg·ha−1 as either a single foliar spray immediately after transplanting or as two consecutive sprays seven days apart. Transient stomatal closure with ≤ 100 mg L−1 of s-ABA provided protection from heat stress with little or no negative side effects and resulted in higher early and total season yields than the untreated control. Both the single and double applications of kaolin consistently protected strawberry transplants from heat stress, enhancing photosynthesis as well as early and total marketable fruit weight. Since the double application of kaolin provided higher early marketable fruit weight than the single kaolin application, the double applications of kaolin appear to have better potential than the single application for mitigating heat stress in sub-tropical conditions during strawberry plug transplant establishment.
