Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

OBJECTIVE To explore the correlation between maternal magnetic field (MF) exposure in daily life and embryonic development. METHODS A cross-sectional study was conducted among 149 pregnant women who were seeking induced abortion of unwanted pregnancies. Participating women were asked to wear an EMDEX Lite magnetic field meter for a 24-h period to obtain MF exposure level within 4 weeks follow...

Sexual differences were investigated to determine the significance of flower bud abortion in the dioecious shrub Aucuba japonica Thunb. The mean number of flowers per inflorescence and the mean number of flowering inflorescences (as opposed to aborted inflorescences) per individual were greater in males than in females in 1997 and 1998. Reproductive investment by males was 0.4-times (1997) and ...

Tropical evergreen perennials undergo recurrent flush growth, and their terminal buds alternate between growth and dormancy. In sharp contrast to the intensive studies on bud development in temperate deciduous trees, there is little information about bud development regulation in tropical trees. In this study, litchi (Litchi chinensis Sonn.) was used as a model tropical perennial for morphologi...

Abstract Idesia polycarpa Maxim is described as a dioecious species, in which flowers are female or male, but we have also found individuals with bisexual flowers. The study aimed to provide the theoretical basis for artificial control on flowering, fruiting, and floral initiation of species. morphological anatomical structure female, I. was studied. In this study, routine paraffin section obse...
