Floating rowcover (R), Dupont's “Lawn and Garden Blanket”, with 75% to 80% light transmittance, was applied on black plastic mulch (M) and over transplanted seedlings of tomato (Lycopersicon esculentum). Peto Seed's fresh market (F) `Al Wadi' and long shelf-life (L) `PSX 19392' were transplanted on 11 Apr. 1995 to drip-irrigated beds that were covered with M or not covered (C). The R was removed 4 (R1) or 5 (R2) weeks after its application. The climate is temperate with ≈200 days frost-free and 400 mm rainfall. Each cultivar was grown in a field with the treatments randomized in a complete block with four replications. Fruit harvest was done weekly for 6 weeks. Yield of the first 2 weeks was considered indicative of earliness. Yield earliness was enhanced by the shorter period treatment (R1) with the L cultivar showing more response to R1 (P < 0.05) than the F cultivar. Early average fruit weight was comparable among all treatments (P > 0.05) in both cultivars, but total average fruit weight was increased by R1 in L cultivar. (P<0.05). Total yield was comparable among the treatments in F cultivar (P > 0.05) and was lowest under M treatment in the L cultivar (P < 0.05). We recommend using R for shorter periods on tomato grown in a dry temperate climate, where clear skies can cause excess heat build up under rowcovers during day time.

Various stem-training systems were applied to greenhouse-grown `Mustang' cucumber (Cucumis sativus L.) plants at two production stages. Training systems determined the number of stems per plant, orientation of laterals, and leaf: fruit ratio. Training systems permitting high canopy light penetration resulted in darker fruit and a longer shelf life. Shelf life was positively related to rapid fruit growth in Expt. 1 but not in Expt. 2. Training systems to achieve a long shelf life of greenhouse-grown long English cucumber are described.

`SuperMac' (Malus ×domestica Borkh) is being released as a replacement for `Spartan', which is presently being grown in Eastern Canada for its excellent shelf life. However, it is susceptibility to scab [Venturia inaequalis (Cke) Wint.], the most common apple disease. This new cultivar produces larger fruit than `Spartan' and is resistant to apple scab. It is very attractive (Fig. 1), has a pleasant taste and an excellent shelf life, and keeps very well and longer compared with the `Spartan'. `SuperMac' is a `McIntosh'-type apple. The tree is hardy to –30 °C, and the fruit and leaves are resistant to the common races of apple scab resulting from the presence of the V f gene derived from Malus floribunda 821.
