Petal wilting and/or abscission terminates the life of the flower. However, how wilting and abscission are coordinated is not fully understood. There is wide variation in the extent to which petals wilt before abscission, even between cultivars of the same species. For example, tepals of Lilium longiflorum wilt substantially, while those of the closely related Lilium longiflorum×Asiatic hybrid ...

As a devastating holoparasitic weed, Orobanche aegyptiaca Persoon. (Egyptian broomrape) causes serious damage to agricultural production and threatens economic development, which has raised widespread concern. The present study was conducted to determine whether lilies have the potential to be used as 'trap crops' for controlling O. aegyptiaca Persoon. In the experiments, the ability of three p...

To prolong the storage period of fresh Lilium longiflorum, maintain its quality during storage, and optimise controlled atmosphere (CA) parameters. In a single-factor experiment, temperature, humidity, O2 CO2 concentrations were considered as primary factors affecting CA L. longiflorum. Then, comprehensive score was optimised using back propagation neural network combined with empirical data. F...

We aimed to produce intergeneric hybrid plants with only one or a few alien chromosomes via microprotoplast fusion for genetic improvement and chromosome studies in Liliaceous ornamental plants. In order to apply this technique, it is essential to establish an efficient system for mass-preparation of microprotoplasts. We have established 2 different systems for isolating microprotoplasts, one f...

A large difference was found in the activities of oligomycin-sensitive mitochondrial F0F1-ATPase isolated from different tissues of Lilium longiflorum plants. The enzyme activity of F0F1-ATPase in pollen was the highest, while that in bulbs was the lowest. When ATPases were cross-reconstituted from F1-ATPases and F1-depleted submitochondrial particles (SMP), ATPases reconstituted from F1-deplet...

The product of myo-inositol-1-phosphate synthase, EC 5.5.1.4, from mature pollen of Lilium longiflorum Thunb., cv Ace (Easter lily) and that of myo-inositol kinase, EC 2.7.1.64, from wheat germ has been identified as 1l-myo-inositol-1-phosphate by gas chromatography of its trimethylsilyl-methyl phosphate derivative on a glass capillary column bearing a chiral phase.

UNLABELLED PREMISE OF THE STUDY Ten microsatellite primers were developed to obtain information on genetic variation in Lilium longiflorum, a bulbous species showing high intraspecific genetic differentiation. • METHODS AND RESULTS Of 61 microsatellite loci isolated using the dual suppression PCR technique, 10 loci were effective to characterize and estimate genetic variation in two popula...
