TL;DR: In this paper, a survey of nine greenhouse ornamental species (Begonia, Cyclamen, Gardenia, Gloxinia, Hibiscus, Impatients, Pelargonium, Poinsettia and Schefflera) has been carried out concurrently with the measurements of evapotranspiration rate.

TL;DR: It was concluded that although osmoconditioning alleviated NaCl-induced stress during germination, emergence and early growth of cucumber, the benefits of treatment did not persist beyond the seedling stage.

TL;DR: A simple cost-benefit analysis has shown that the use of B. impatiens as pollinators of greenhouse sweet pepper is likely to increase the profitability for both cultivars.

TL;DR: Low temperatures promoted floral induction of mango, whereas water stress promoted growth of florally induced buds, and floral morphogenesis was induced by chilling temperatures.

TL;DR: It is concluded that within cucumber genetic variation for the contribution of the root system to growth and fruit production exists and grafting experiments offer possibilities to plant breeders for improvement of fruit production.

TL;DR: Early season water stress, resulting in a leaf water potential of less than −2.5 MPa, should be avoided in Asian pear as it was shown to have negative effects on water relations, photosynthesis, and fruit growth.

TL;DR: The ‘dynamic’ rest completion prediction model was considerably more accurate than the currently used ‘Utah’ model, for estimating the rest requirement of the nectarine cultivars ‘Sunlite’, ‘Flavortop’ and ‘Fantasia’.

TL;DR: In this article, the melon cultivar "Galia" was grown at three plant densities (2, 4 and 8 plants m−2) and four irrigation salinity levels (ECw 1.2-8.0 dS m−1).

TL;DR: In this paper, a simple crop model with two state variables, namely structural biomass and carbohydrate pool, was used to explore the effect of alternative temperature regimes on greenhouse crop production, assuming a repeated environmental cycle, certain qualitative predictions could be made.

TL;DR: It is suggested that disturbance of carbohydrate metabolism in the root is a primary factor responsible for the growth inhibition and dysfunctions of cucumber roots grown at supraoptimal root temperatures.

TL;DR: In this article, a cucumber (Cucumis sativus L., hybrid ‘Pepinex’) was grown in soil culture over a range of NaCl concentrations (0−190 mM) in a glasshouse and the effects on gas exchange, water relations, ion content and leaf growth were examined.

TL;DR: Growing shoot tips of nursery trees of the apple cultivar ‘Red Boskoop’ on rootstock M.9 were sprayed four or eight times at weekly intervals with 6-benzyladenine, and the most active BA treatments enlarged the zone of lateral emergence by 50 cm.

TL;DR: The results suggest partial compensation of the alternate habit by enhancement of female floral quality and an increase in fruit set when low levels of flowering occur.

TL;DR: Flowers of soursop appeared to be protogynous and, following pollination, they entered a quiescent period of 6–15 weeks, during which time the stigmatic surface typically developed a sooty deposit, and the time taken to reach fruit maturity from this ‘take-off' point was found to be 15–21 weeks.

TL;DR: A positive correlation between seed content (number and weight) and fruit weight has been determined for summer and late fruits of the two major Italian cultivars of Opuntia ficus-indica, ‘Gialla’ and ‘Rossa’.

TL;DR: Observations indicate that many of the shoots regenerated from thawed shoot tips were adventitious in origin and were derived from the epidermis of the shoot tip.

TL;DR: In apple and pear there was no effect of the autumn temperature on fruit set, although bloom temperature was the same, the EPP was extended when the temperature was lowered just after bloom, resulting in a better fruit set in that treatment.

TL;DR: Stem elongation of young plants of Lycopersicon esculentum Mill and Dendranthema morifolia Ramat and ‘Choral Charm' was continuously measured under greenhouse conditions with a high degree of resolution, using linear voltage differential transducers.

TL;DR: In this article, a model is described which predicts the time to curd initiation, and the duration or rate of curd growth of cauliflowers, with data collected from commercial crops grown during the 1989, 1990 and 1991 seasons.

TL;DR: The results obtained with the improved medium for the in vitro pollen germination related more accurately with the number of seeds per fruit, at cold night temperature, than did the staining tests employed.

TL;DR: A medium that will support excellent growth of Pistacia vera and hybrid pistachio shoots was developed and gave improved shoot growth, survival when rooting, and acclimation compared with a sucrose based medium.

TL;DR: The relative growth rate ex vitro was lower for plants cultured in a CO2-enriched atmosphere in vitro than for those cultured at 0.034% CO2, and the development of plants (on a leaf area basis) from these CO2 treatments was no longer significantly different.

TL;DR: Cluster analysis using 11 enzyme loci classified the species into five groups and identified phylogenetic relationships of these species as S. melongena and S. incanum, which are related to Solanum indicum, sanitwongsei and surattense.

TL;DR: Fruit splitting in the mandarin orange cultivar 'Nova' is related to the presence of an open stylar end in the fruit, which arises from a cavity present at the bas e of the style, and is formed in a variable proportion of fruits.

TL;DR: The use of this method in plants produced in vitro from seeds of ‘fruiting male’ of Actinidia deliciosa revealed the existence of individuals of high ploidy level, probably 9 ×, which to the authors' knowledge have never been noticed and do not seem to have any varietal potential.

TL;DR: Trichoderma biomass can increase flowering and shoot growth of petunia, marigold and verbena under a range of cultural conditions.

TL;DR: Alteration of light quality in the greenhouse can be used to control height of rose plants but extended shipping at high temperatures could result in leaf yellowing possibly because of reduced carbohydrate status.

TL;DR: Therefore, a BAP-GA 3 medium is not recommended for regular use, although it can be interposed in a culture series on the BAP medium, to stimulate periodic axillary bud development.

TL;DR: DNA fingerprint analysis of genetic relatedness between rose genotypes, using human-derived minisatellite probes, correctly reflected relationships within and between categories of rose plants.

TL;DR: Flowering was induced in 7-month-old × Doriella Tiny (Doritis pulcherrima × Kingiella philippinensis) explants in an vitro system and BA was required for the formation of floral buds on explants under certain nutritional conditions, including the appropriate content of sucrose and nitrogen in the culture media.
