The growth response of 2 vegetable crops to 5 rates of applied phosphorus (P)in the presence or absence of an existing network of extraradical mycorrhizalmycelium was determined in 2 greenhouse pot experiments (Expt 1, autumnwinter; Expt 2, summer autumn) using a low-P growth medium (6 or 5 mgNaHCO3-extractable P/kg for Expt 1 or 2,respectively). In both experiments, capsicum(Capsicum annuum L.) and tomato(Lycopersicon esculentum Mill.) plants were grown at 0(P1 ), 9.2 (P2), 27.5(P3 ), 82.5 (P4 ), or 248(P5) mg P/kg oven-dry soil (spot-placed at sowing)within a nylon mesh (pore size 44 µm). The mesh excluded roots from theoriginal sunflower (Helianthus annuus L.) host plants,to which either live (VAM+) or killed (VAM–) mycorrhizal[Glomus etunicatum Becker & Gerdemann andGlomus mosseae (Nicol. & Gerd.) Gerdemann & Trappe] inoculum was added at sowing. The mesh did allow fungal hyphae togrow into the growth medium contained by the mesh.Whereas VAM+ plants generally had higher P concentrations in indextissues than VAM– plants at low P rates, a concomitant increase in drymatter yield was restricted to the P1 rate. AtP1 in Expt 2, the increase in the dry weight of wholeplants as a result of VAM colonisation was as large as 91.7-fold and 17.9-foldfor capsicum and tomato, respectively. Root starch analysis indicated that thelower dry matter yields of VAM+ plants than of VAM– plants at≥P2 could be attributed to insufficient photosynthateproduction by VAM+ plants to meet the carbon (C) demand of both host andendophytes within the relatively low-light environment of the greenhouse(average daily solar irradiance of 8.4 MJ/m2 forExpt 1 and 13.4 MJ/m2 for Expt 2).The growth response of vegetable crops grown within the greenhouse fromcolonisation by an established mycorrhizal mycelium appears to depend on acritical balance of P and C supply; i.e. at P1, P wasmore limiting than C, and the increased uptake of P as a result ofcolonisation of plant roots by VAM resulted in a growth response. At higher Prates, C was more limiting than P due to low light in the greenhouse, and theadditional demand for photosynthate imposed by the endophytes on the hostresulted in a growth depression relative to non-mycorrhizal plants.

This greenhouse study investigated the effects of the addition of vesicular-arbuscular mycorrhizal (VAM) inoculum (Glomus mosseae [Nicol. & Gerd.] Gerdemann & Trappe and Glomus etunicatum Becker & Gerdemann) on capsicum (Capsicum annuum L. cv. Target), sweet corn (Zea mays L. cv. Snosweet), and tomato (Lycopersicon esculentum Mill. cv. Floradade) grown in a low P sandy loam (6 mg NaHCO3-extractable P/kg) with 5 rates of P (0, 10.3, 30.9, 92.7, or 278 mg P/kg oven-dry soil; P1, P2, P3, P4, or P5, respectively) and 2 rates of N (50 or 200 mg N/L in irrigation solution; N1 or N2, respectively). The growth periods (from sowing to harvest) for the 3 crops were as follows: 27 August-22 November 1993 for capsicum, 26 August-29 October 1993 for sweet corn, 31 August-22 October 1993 for tomato. For VAM-inoculated capsicum at PI, the dry weight (10.03 g/plant) and mean P concentration in the 5 youngest mature leaves (0.14%) were greater (P < 0.05) than those for uninoculated plants (0.28 g/plant; 0.09% P); a high coefficient of variation necessitated the use of log, transformed data to show differences. At low P rates, dry weight of sweet corn (P1, P2) and tomato (P1) plants colonised with VAM did not differ (P > 0.05) from uncolonised plants, despite inoculated plants having higher P concentrations in index tissues. At intermediate P rates, dry weights of inoculated plants were lower (P < 0.05) than those of uninoculated plants of sweet corn at P3 (81.1 and 102.2 g/plant, respectively) and of tomato at both P2 (11.7 and 34.5 g/plant, respectively) and P3 (39.6 and 52.1 g/plant, respectively). For all 3 crops, a lack of VAM response at high P ( >P4) was related to a lower (P < 0.05) VAM colonisation. The percentage root length colonised by VAM at P5 was only 6.8, 19.6, and 2.4% of that measured at P1 in the case of capsicum, sweet corn, and tomato roots, respectively. Increasing N concentration in the irrigation solution from 50 to 200 mg/L increased (P < 0.05) VAM colonisation of sweet corn (from 28 8 to 36 2%), but had no effect on capsicum and tomato.

Postharvest Ripening

The influence of post-harvest ripening conditions of pepper Aleva NK picked in red maturity stage on the composition of volatiles in spice paprika was investigated by GCMS. The post-harvest ripening in the dark and under daylight was conducted under semicontrolled conditions for two weeks. The obtained chromatograms indicated that the aroma of investigated spice paprika consisted of a large number of volatile compounds regardless of the application and conditions of the post-harvest ripening. The main volatiles of the analyzed paprika samples were fatty acids and their esters, terpenes and terpenoides and aldehydes and ketones. The share of fatty acids and their esters decreased during the post-harvest ripening, and the ripening in the dark favored the decrease. The share of terpenes and terpenoides and the share of aldehydes and ketones in the total volatiles increased during the post-harvest ripening. The post-harvest ripening in the dark favored the increase of the share of terpenes and terpenoides, while the ripening under daylight favored the increase of the share of aldehydes and ketones.
