Italian parsley (parsley) Petroselinum crispum, summer savory (savory) Satureja hortensis, sweet marjoram (marjoram) Origanum majoranna, and thyme Thymus vulgaris, were evaluated for their yield potential in multiple harvest during the fall–winter–spring (Dec.–May 1997–98). The herbs were grown with the full-bed polyethylene mulch-micro (trickle) irrigation system. Experimental design was a split-plot arranged in three randomized complete blocks. Main plots were two N–P–K treatments: 0 N–P–K or N and K from a liquid 4N–0P–3.32K fertilizer injected at 0.77 N and 0.64 K kg/ha per day. In the subplots, compost was applied in a 4 to 8 inches wide band on the pre-bed at 0x, 1x, 2x, and 4x rates (1x = 4.5 t·ha–1). Parsley and marjoram yields in the first three harvests and thyme yields in the first two harvests were similar with 0x compost and N + K injected fertilizers to yields with 3x and 4x compost rates with no injected N + K fertilizers. For the season, yields were higher with injected N + K fertilizers with or without compost, than in the compost treated plots with no N + K fertilizers.

Pigments in stored parsley leaves (Petroselinum crispum Nym.) were monitored to determine if degradative products of chlorophyll (chl) differed while under different types of atmosphere. The leaves were stored in a closed container under a stream of humidified air at 20C with or without 10 ppm ethylene and with or without 10 percent oxygen and 10 percent carbon dioxide. Analysis of pigments with HPLC showed that chl a and b decreased sharply with or without ethylene and the decrease was considerably less under CA. Chlorophyll a-1, the oxidized form of chl a, was initially low, and the level decreased slightly with all of the storage conditions. Chlorophyllide was also low, but it increased slightly during storage. Xanthophyll derivatives, which appeared to be the esterified xanthophylls, increased slightly during storage. These results indicate that chl degradation in stored parsley leaves was hastened by ethylene or suppressed by CA condition and the pathway of chl degradation did not appear to be altered by the different storage atmospheres.

Germination studies indicated that increasing priming duration (-1.0 MPa at 20 °C for 7, 14, or 21 days) increased `Moss Curled' parsley [Petroselinum crispum (Mill.) Nyman ex A.W. Hill] germination rate quadratically and seed moisture content linearly. A histological and anatomical study was conducted to identify and/or quantify principle mericarp organ or tissue volume changes influenced by priming duration. Embryo volume increased as priming duration increased from 7 to 21 days (0.014 to 0.034 mm3), and this was due more to radicle (0.007 to 0.022 mm3) than to cotyledon (0.006 to 0.011 mm3) growth. Concomitant with increased embryo volume was increased volume of the depleted layer (space formation, surrounding the embryo), from 0.038 after 7 days to 0.071 mm3 after 21 days, and increased hydrolysis of central endosperm (a thick-walled endosperm type). In nonprimed mericarps, central endosperm cells constituted 97% of the endosperm volume. The remaining 3% was comprised of 1% depleted layer and 2% distal endosperm (small, thin-walled, and irregularly shaped endosperm cells). During 7 or 21 days of priming, ≈10% or 40%, respectively, of central endosperm cells were hydrolyzed centrifugally around the embryo with a corresponding decrease in volume of central endosperm with thick cell walls. In addition, distal endosperm cells adjacent to the depleted layer, containing reserve materials, were digested of contents following 21 days priming, and sometimes, following 7 days priming. A long priming duration resulted in degradation of pericarp tissues, as indicated visually and by a decline in pericarp volume. We hypothesize that priming duration of parsley primarily influences radicle growth and centrifugal digestion and utilization of central and distal endosperm, resulting in a larger depleted layer required for embryo volume increases. Secondary events influenced by priming duration include cotyledon growth and degradation of pericarp tissues.
