“…Dwarfing rootstocks can increase productivity and improve fruit quality by reducing tree vigor [37,38]. This study aimed to investigate the effects of Cerasus humilis rootstocks on the growth, development, and fruit quality of peach trees, as well as to explore the underlying mechanism of tree dwarfing.…”

Peach trees play an essential role as an economic crop in China. However, the increasing cost of labor has led to a decline in the benefits of peach cultivation. The use of dwarfing rootstock technology can increase planting density, reduce tree height, decrease labor requirements, and reduce production costs. The Cerasus humilis (Bge). Sok. is a promising dwarfing rootstock for peaches owing to its small tree size, abundant resources, strong resistance, and adaptability. In this study, we investigated the effect of Cerasus humilis rootstocks on peach growth and development, and related gene expression. We used Ruipan 4/Cerasus humilis and Ruipan 4/Amygdalus persica L. as experimental materials to measure the growth and fruiting characteristics of two-year-old Cerasus humilis rootstocks. In addition, we used bioinformatic methods to explore the effect of Cerasus humilis rootstock on peach growth gene expression. Our results showed that Cerasus humilis rootstocks can dwarf peach trees, reduce branches, increase pollen count and stigma receptivity, shorten spore development, and promote protein accumulation in the late stage of fruit maturity. The Cerasus humilis rootstock reduced the growth hormone content in peach trees while upregulating the expression of growth-related PpYucca5 and PpYucca2 genes. PpYucca6 expression was downregulated in the early stage of shoot growth and upregulated in the middle stage. By reducing the content of growth hormones, peach trees can be dwarfed, but their impact on fruit quality is minimal. These results indicate that Cerasus humilis is a suitable peach dwarfing rootstock and can provide a theoretical reference for the future breeding of peach dwarfing rootstocks.

“…Berdasarkan pengkajian tersebut, beberapa peneliti juga telah melaporkan pendugaan vigor tanaman berdasarkan pengkajian anatomi. Karakter anatomi yang berpengaruh terhadap vigor tanaman adalah karakter xylem dan floem (Saeed et al, 2010;Zorić et al, 2012;Bruckner and DeJong, 2014). Karakter tersebut berpengaruh terhadap konduktansi hidrolik (Tombesi et al, 2010;Zach et al, 2010).…”

Vigor tanaman jeruk dipengaruhi oleh batang bawah yang digunakan. Penelitian bertujuan untuk mendapatkan korelasi antara karakter anatomi akar dan batang terhadap tinggi tanaman jeruk batang bawah dan mendapatkan variabel prediksi vigor tanaman jeruk keprok RGL. Penelitian dilaksanakan di KP-Tlekung, Balitjestro mulai bulan Juni 2019 – Maret 2020. Penelitian menggunakan batang bawah JC, Citrumelo dan Kanci dengan batang atas jeruk keprok RGL. Percobaan dilaksanakan dengan rancangan acak kelompok, lima kali ulangan. Hasil penelitian menunjukkan bahwa pertumbuhan JC dan Citrumelo sama dan lebih tinggi dibandingkan Kanci. Ketiga jenis batang bawah memiliki karakter anatomi yang berbeda. Hasil analisis korelasi menunjukkan bahwa karakter persentase dan luas pembuluh xylem baik pada akar maupun batang berkorelasi positif terhadap tinggi tanaman batang bawah. Batang bawah kanci memiliki persentase dan luas pembuluh paling kecil. Batang bawah JC memiliki persentase xylem dan rata-rata luas pembuluh xylem tertinggi baik pada irisan melintang akar maupun batang. Batang bawah Citrumelo memiliki densitas pembuluh xylem/mm2 tertinggi. Hasil evaluasi pada tanaman jeruk keprok RGL umur tiga tahun menunjukkan bahwa batang bawah JC dan Citrumelo menyebabkan tinggi tanaman dan volume kanopi lebih tinggi dibandingkan pada batang bawah Kanci. Karakter persentase dan luas pembuluh xylem dapat digunakan sebagai parameter penduga vigor tanaman jeruk RGL. Kata kunci: Jeruk batang bawah, jeruk keprok RGL, karakter anatomi, xylem, vigor

“…The rootstock influence on the water supply and transport of dissolved substances to the aboveground part, as well as the metabolism and translocation of plant hormones, are considered as potential reasons for vigor reduction in trees grafted on size-controlling rootstocks [2,8]. Secondary xylem characteristics, especially the vessel lumen area and number, as well as the closely related root hydraulic conductivity, are widely accepted parameters of low-vigorous rootstock selection [9][10][11][12][13][14][15][16]. Water conductance capacity through the plant can be estimated by calculating the theoretical hydraulic conductivity of participating tissues, which is directly related to the overall tree growth potential [13,17,18].…”

Over the past few decades, numerous studies investigated the vigor and productivity of fruit species depending on the rootstock on which they were grafted, but the exact size-controlling mechanism itself has not been fully elucidated, nor were the rapid rootstock selection methods defined. Thus, this study aimed to assess the root anatomical characteristics and their influence on the overall ‘Summit’ cherry tree vigor to confirm the size-controlling effect and establish an effective protocol for rapid rootstock selection. Plant material included three cherry species (Prunus cerasus, Prunus fruticosa, and Prunus mahaleb) and interspecific hybrid ‘Gisela 5′ (P. cerasus × Prunus canescens) as a control. The detailed anatomical analysis included root samples with the differentiated secondary structure taken from the sampling depth of 10–15 cm. Roots with percentages of vessels ≈40%, ≈50%, and ≈10% belonging to size-classes ˂700 µm2, 700–2000 μm2, and ˃2000 µm2 (respectively) are presumed to provide optimal amounts of water solution to the scion, without compromising plant vitality, drought tolerance, and size-controlling effect. Statistically significant correlations were determined between anatomical properties (the percentage of vessels, especially ˃2000 µm2, xylem porosity, and hydraulic conductivity, both per mm2 and total root) and vegetative growth in the juvenile vegetative phase, indicating direct vessel size influence on plant vigor and its employment in size-controlling cherry rootstock selection.
