There exist hundreds of cultivated tropical and subtropical fruit species, most of which are arboreal. Among these are mango (Mangifera indica), which thrives from the equator (zone 11) to the subtropical limits of tropical zone 10b of the northern and southern hemispheres (Cathey, 1990; Jordan, 2001); Citrus sp., which have a growing range that extends for some species from near the equator in...

The variation in flowering abundance was studied in a Norway spruce seed orchard, located in southern Finland (62°13'N, 25°24'E), consisting of 67 clones from northern Finland (64°–67°N). The flowering variation in 1984–1996 was studied at the annual, clonal and graft level. In addition, the genetic diversity of an imaginary seed crop was estimated using a concept of status number. The between-...

Flowering control is one of the several strategies for gene containment of transgenic plants. TERMINAL FLOWER 1 (TFL1) is known to be involved in the transcriptional repression of genes for inflorescence development. Two TFL1 transcripts with different 3' UTR were cloned from black cherry (Prunus serotina Ehrh.) using reverse transcription-polymerase chain reaction (RT-PCR) and rapid amplificat...

Abstract Hybridization has been associated with increased invasiveness in plants. In North America, the hybrid aquatic plant Myriophyllum spicatum × sibiricum (hybrid watermilfoil, hereafter HWM) is a cross between non-native invasive Eurasian watermilfoil ( M. , EWM) and native northern NWM). Lab-based trials have demonstrated higher growth rates HWM compared to EWM NWM, but these patterns not...

this research was carried out at the research farm, faculty of agriculture, bu-ali sina university in growing season of 2011-2012. the aim of research was to evaluate the effect of foliar application of nano-iron chelate and bacterization of mesorhizobium bacteria on root nodulation, growth, grain yield and yield components of chickpea under rainfed conditions. a randomized complete block desig...

Abstract The present experiment was conducted to determine the effect chemical fertilization rates and foliar application of plant growth regulators PGRs (Kinetin or Napthaleneacetic Acid (NAA) their interactions on growth, flowering, composition Ervatamia coronaria plants. plants were fertilized monthly with NPK at rate 2, 4 6 g pot-1, in addition control Plants received treatments sprayed eit...

An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh to assess the effect of weeding on growth, yield and yield contributing characters of mungbean (Vigna radiata L.) cv. BINA mung4 during October 2011 to February 2012. The experiment was laid out in a randomized complete block design with four replications. The trial comprised seven tre...

This field experiment was conducted during the 2021 cropping season at Prince Abubakar Audu University Research and Demonstration farm, Anyigba in Southern Guinea Savana Agro Ecological Zone of Nigeria to determine performance maize varieties under influence NPK 20:10:10 Urea fertilizer application. A Randomized Complete Block Design (RCBD) used with three replications. The treatment consisted ...
