Two field experiments were used to determine the yield potential of 'Long Pod' cayenne hot peppers due to foliar application of 528 ppm each of chlormequat chloride. ethephon, and ancymidol. Applications were either made at bud formation, fruit development or fruit ripening periods. At last harvest, samples of marketable red-ripe fruits from the border rows of both 'Long Pod' cayenne and “Oriental-l” hot pepper plots were used for hot pepper sauce formulations. Two sets of 32 panelists each, were used to evaluate both the newly formulated experimental (ICES-1 and EHS-2) and commercial (CHS-1 and CHS-2) hot peppers sauces for quality. In 1990, marketable yield was highest due to chlormequat chloride. and for application made at fruit ripening. In 1991, marketable yield was highest due to ancymidol application, and for application made at fruit ripening. Mean sensory scores for hot sauce appearance, flavor and texture were generally highest for experimental hot sauces, whereas pungency scores were highest due to “CHS-1” commercial hot sauce.

Diurnal and seasonal water relations and ecophysiological variables (soil humidity, transpiration, evapotranspiration, stomatal resistance, morphological changes, production), matched with some microclimatological variables, were studied in a hot pepper (Capsicum frutescens) experimental plot. Two treatments of plants with plastic mulches were assigned, black and blank-opaque, to compare them with plants without a mulch, established at the Experimental Station of CIBNOR in La Paz Baja California Sur, Mexico. Plants with blank-opaque plastic mulch showed the highest values of flower number, fruit production, leaf area, and canopy-projected area. Also, the biggest evapotranspiration rates were recorded from January to April for plants under the blank-opaque plastic mulch. Soil water content appeared to be a primary determinant factor for production. Soils under the blank-opaque plastic mulch had the biggest water content along the experiment. Plants without any plastic mulch had the lowest availability of soil water, rendered the lowest fruit production, and registered the highest evapotranspiration rates. May and June were the months with the highest air temperature during the experiment. Plants with black plastic mulch had intermediate records among the other two groups. When plants were allowed to face a drought stress, they responded through an osmotic adjustment for maintaining a low water potential, and thus supporting a partial turgor pressure. This adjustment was evident to be coupled with a stomatal regulation in order to minimize the loss of water through the transpiration process. Some drought tolerance strategies as a leaf size reduction were more evident in plants without a mulch.

Several plant species that are not consumed by animals were collected, extracted with organic solvents, and tested at different venues for their effectiveness as animal feeding repellents. Species with the most repellent activity were daffodil (Narcissus pseudo narcissus), bearded iris (Iris sp.), hot pepper (Capsicum frutescens), catnip (Nepeta cataria) and peppermint (Mentha piperita). Considerable effort was expended to isolate and identify compounds from these species responsible for repellent activity. Eight chemicals have been isolated and purified, and four of them have been identified. Both daffodil and catnip contain more than one repellent, but none of the four compounds identified were common to both species. Combinations of extracts from more than one plant species proved to have more repellent activity than extracts from individual species used alone. In several tests these plant extracts proved to be as effective or better than available commercial repellents. A plethora of additives and surfactants were tested to increase repellent activity by enhancing the spreading, penetration or persistence of the extracts.

The effect of ethephon on fruit maturity in tabasco pepper (Capsicum frutescens L) was investigated in greenhouse studies. Two lines of tabasco pepper (`McIhenny Select' and `Hard Pick') that differ in ease of separation at the calyx-pedicel separation zone were used. Individual flowers were tagged at anthesis and intact fruit were treated with ethephon (500, 1000 μL) 29, 32, 35, and 38 days after anthesis. Untreated fruit were used as controls. The normal development from anthesis to mature red is 45 to 47 days for both lines. Ethephon treatment to tabasco fruit of both lines at 29 and 32 days after anthesis was effective in enhancing ripening by 3 to 7 days. `Mclhenny Select' ethephon treated fruit 35 days after anthesis were not affected. In contrast, `Hard Pick' fruit treated with ethephon at the high rate (1000 μL) 35 and 38 days after anthesis resulted in enhanced ripening compared to that of the control. These results indicate that the two tabasco lines differ in response to ethephon.

Viral Helicase

There are many nonpathogenic viruses that are maintained in a persistent lifestyle in plants. Plant persistent viruses are widespread, replicating in their hosts for many generations. So far, Endornaviridae is the only family of plant persistent viruses with a single-stranded RNA genome, containing one large open reading frame. Bell pepper endornavirus (BPEV), Hot pepper endornavirus, Capsicum frutescens endornavirus 1 (CFEV 1) have been identified from peppers. Peppers are native to Central and South America and, as domesticated plants, human selection accelerated their evolution. We investigated the evolution of these endornaviruses in different peppers including Capsicum annuum, C. chacoense, C. chinense, C. frutescens, C. baccutum, and C. pubescens using two fragments from the viral helicase (Hel) and RNA dependent RNA polymerase (RdRp) domains. In addition, using single nucleotide polymorphisms, we analyzed the pepper host populations and phylogenies. The endornaviruses phylogeny was correlated with its Capsicum species host. In this study, BPEV was limited to C. annuum species, and the RdRp and Hel phylogenies identified two clades that correlated with the host pungency. No C. annuum infected with CFEV 1 was found in this study, but the CFEV 1 RdRp fragment was recovered from C. chinense, C. frutescens, C. baccutum, and C. pubescens. Hence, during pepper speciation, the ancestor of CFEV 1 may have evolved as a new endornavirus, BPEV, in C. annuum peppers.

Development Of Resistance

<p>The use of chemical insecticides in crop production has resulted in increased food production in Africa, but their use has resulted in the destruction of beneficial organisms and development of resistance by some insects to the insecticides. The effectiveness of garlic <em>Allium sativum</em> and hot pepper, <em>Capsicum frutescens</em> in controlling the pests of cabbage, <em>Brassica oleracea</em> was evaluated. These botanicals were compared with a standard chemical insecticide Attack® (Emamectin benzoate). The experiment was conducted in a randomized complete block design, with 3 treatments and a control, each of which was replicated 3 times. <em>Plutella xylostella, Brevicoryne brassicae, Hellula undalis</em> and <em>Trichoplusia ni</em> were found on cabbage plants. Significantly fewer of them were found on the treated plants than the control plants. The use of the plant extracts resulted in a reduction in mortality ranging from 10.76% to 55.94%. Fewer natural enemies of <em>B. brassicae</em> were sampled on the insecticide-sprayed plots than the garlic and pepper-sprayed plots. The cost of protecting cabbage plants from insect infestation using Attack was higher than the botanicals. Garlic-treated plots recorded the highest cost: benefit ratio of 1:16 while Attack®-treated plots recorded the least of 1: 9.2. The control effects of the botanicals compared favourably with that of the chemical insecticides. Thus these botanicals can be used as substitutes to chemical insecticides.</p>
