Temperature integration where high day temperatures are compensated by lower night temperatures is one strategy that can be used to reduce energy consumption in greenhouses. Crop tolerance to temperature variation is a prerequisite for using such a strategy. Greenhouse experiments were conducted on tomatoes cvs, Capricia, Mecano and Cederico in order to investigate the effect of different day/n...

in the current research, salicylic acid and putrescine treatments solutions each with 0, 0.5, 1, and 2 mm/l levels were sprayed on the ‘granny smith’ apple trees in three preharvest stages. the treatments were applied based on factorial experiment in the randomized complete block design. weight loss, fruit firmness, total soluble solids (tss), titratable acidity (ta), ph, tss/ta, peel color, an...

Standard colour measurements can pose a serious problem for interpretation. For tomatoes the maturity at harvest does affect the colour that can maximally be obtained during postharvest storage. For more mature fruit up to 2 units (compared to 18 units tops) were found. This effect was ascribed to the level of a precursor produced during growth. More mature fruit also exhibit a more pronounced ...
