Journal ArticleDOI
TL;DR: Continuous CO 2 enrichment during the light period seems to be superior to intermittent CO 2 application, and during periods of ventilation of the greenhouse increases the yield of cucumber, while some other species seem to be less affected.

217 citations


Journal ArticleDOI
TL;DR: The effect of different spectral energy distributions on the growth of Chrysanthemum × morifolium Ramat, Lycopersicon esculentum Mill.

195 citations


Journal ArticleDOI
TL;DR: Flowering plants appeared more sensitive to C2H4 treatment than foliage plants, exhibiting abscission of flowers, flower buds or whole inflorescences after 24 h.

88 citations


Journal ArticleDOI
R. Chée1, R.M. Pool1
TL;DR: An improved medium for shoot multiplication was designed, which differs from others in its lack of added chloride and potassium iodide, and in a lower manganese sulfate concentration.

65 citations


Journal ArticleDOI
TL;DR: In this paper, the effect of pre-harvest AVG (aminoethoxyvinylglycine) treatments on storage life and postharvest behaviour of "Golden Delicious" apple fruits during two consecutive years was investigated.

63 citations


Journal ArticleDOI
TL;DR: Both sexual and asexual methods of propagation of the more important, commercially grown Annona species are reviewed and clonal propagation of some of these species using micropropagation or modified layering techniques is technically feasible.

Journal ArticleDOI
TL;DR: Stomatal conductance and leaf and stem water potentials were measured on peach trees irrigated at 50 and 100% of calculated maximum evapotranspiration in order to determine the influence of soil drying on these indicators of plant water stress.

53 citations


Journal ArticleDOI
TL;DR: Although fruit maturity was unaffected by night temperature, fruit abscission occurred earlier in cool-night fruit, and ACC levels in the fruits were not statistically different between temperature treatments during fruit maturation.

Journal ArticleDOI
TL;DR: Summer pruning, where considered necessary, needs to be adjusted to local conditions and coordinated with other cultural practices, and mostly positive influence of summer pruning on fruit colour by factors in addition to better light penetration is discussed.

49 citations


Journal ArticleDOI
TL;DR: In this article, the release rates in water of three resin-coated controlled-release fertilizers were determined at temperatures in the range 5-45°C. The results showed that after 19 weeks incubation at 20°C, 66% of Nutricote fertilizer remained compared with 58% for Osmocote A and 55% for OpCo-Coated Osmcoote B.

Journal ArticleDOI
TL;DR: In this paper, post-harvest changes in two litchi (Litchi chinensis Sonn.) cultivars "Hei Ye" and "Chen Zi" were studied.

Journal ArticleDOI
TL;DR: The use of leaf protoplast in fusions with protoplasts isolated from embryogenic callus allowed for the visual identification of heterokaryons and suggests the possible utilization of additional physiological parameters in somatic hybridization selection schemes.

Journal ArticleDOI
TL;DR: Tomato, cucumber and sweet pepper were sown in a greenhouse at regular intervals throughout the year and the relationship between the relative growth rate (RGR) and the mean daily light integral (PAR incoming per unit ground area) could be calculated for each species.

Journal ArticleDOI
TL;DR: In this paper, the authors examined the microsomal membrane fraction of apples during 6 months of storage at 0°C in air and in a controlled atmosphere for up to 6 months.

Journal ArticleDOI
TL;DR: The amount of storage carbohydrate accumulated below ground increased by over 30-fold between the time of planting and the winter after the second season's growth, while the number of buds, roots and ferns present during the first 2 years was investigated.

Journal ArticleDOI
TL;DR: The synthetic auxins had a direct stimulatory effect on fruit growth, and no thinning effect was found at the concentration used (7.5 mg l−1).

Journal ArticleDOI
TL;DR: Variation among cultivars was observed in 4 enzymes: esterase, isocitrate dehydrogenease, malate dehydrogenase and acid phosphatase, and the isozyme phenotypes of 13 cultivars were unique.

Journal ArticleDOI
TL;DR: Rapid propagation of Nephrolepis cordifolia was achieved by means of runner tip culture in vitro by using green globular bodies for the multiplication stage, and 160 000 plantlets could be obtained from one runner tip in 6 months.

Journal ArticleDOI
TL;DR: In this article, the relationship between vegetative flushing and leaf N, the timing of fertilizer N application during flowering and fruit set, refinement of leaf and soil sampling; the possible role of K in winter dormancy; leaf symptoms of micronutrient deficiencies; and roles of Zn, B and Cu in fruit set.

Journal ArticleDOI
TL;DR: The water-retaining properties of four hydrogels were examined in distilled water, tap water and in various nutrient solutions, and media were ranked with respect to both parameters.

Journal ArticleDOI
TL;DR: It is demonstrated how isozyme markers can be used to solve problems of cherimoya cultivar identification and to determine the parentage of varieties.

Journal ArticleDOI
TL;DR: Results show that potential yield will be reduced by either low temperatures which restrict vegetative growth or by high temperatures which prevent flower production.

Journal ArticleDOI
TL;DR: The shape and size of detached avocado fruit (Persea americana cultivar 'Hass') were analysed throughout the growing season and the growth of small and large fruits expressed on a logarithmic scale was found to be in close fit.

Journal ArticleDOI
TL;DR: Developmental studies with strawberries must rely on several growth characteristics when assessing photoperiod or temperature effects on a given response, and short days alone cannot induce rest in ‘Earliglow’.

Journal ArticleDOI
TL;DR: Stomatal conductance seemed more sensitive to water stress than transpiration, but leaf temperature only differentiated advanced levels of stress (± 2°C difference between stressed and non-stressed leaves).

Journal ArticleDOI
TL;DR: A negative relationship existed as the number of axillary buds increased as the temperature decreased, and the flowering percentages of the plants treated at 19 13, 25 19 and 31 25° C were 87, 60 and 0, respectively, when the temperature was held constant.

Journal ArticleDOI
TL;DR: Application of bzl6Ade and m-OH-bzl 6Ado to poinsettia and gerbera stock plants at optimum concentration for production of cuttings did not affect rooting of excised shoot cuttments.

Journal ArticleDOI
TL;DR: The study suggested that ‘d'Anjou’ fruits should be harvested quickly when fruits reached the optimum maturity in order to reduce the susceptibility to decay, to gain optimum fruit sizes, and to ripen with an acceptable quality after storage.

Journal ArticleDOI
TL;DR: Cultures were established from the shoot apices (1–2 mm) initiated on a medium composed from Knop's macroelements and Murashige and Skoog's microelements in the presence of 0.5 mg l−1 benzyladenine and survival of potted plants was about 90%.

Journal ArticleDOI
TL;DR: The results revealed that irrigation at 40% available soil moisture resulted in maximum dry-matter production, LAI, CGR and harvest index, resulting in highest fruit yield, although this was not significantly different from that observed with irrigation at 60% ASM.
