δι᾽ ὃ καὶ αἱ γενέσεις κατὰ τὰς ἰδίας ἑκάστων φύσεις· ὅσα μὲν γὰρ ξηρὰ καὶ μονοφυῆ καὶ ἀπαράβλαστα, ταῦτ᾽ οὐδεμίαν, ὡς εἰπεῖν, δέχεται φυτείαν οὔτε ἀπὸ παρασπάδος οὔτε ἀπὸ ἀκρεμόνος· τὴν μὲν ἀπὸ παρασπάδος τῷ μὴ ἔχειν τὰ μονοφυῆ, τὴν δὲ ἀπὸ ἀκρεμόνος καὶ κλωνὸς διὰ τὴν ξηρότητα. ἀεὶ γὰρ τὸ μέλλον βλαστάνειν ἔχειν τε δεῖ τὴν ἔμβιον ὑγρότητα καὶ ταύτην δύνασθαι τηρεῖν. τὰ δὲ φύσει ξηρὰ διὰ τὸ ὀλίγην ἔχειν, ὅταν ἀπὸ τοῦ δένδρου ἀφαιρεθῇ ταχὺ διαπνεῖται καὶ ἐξατμίζεται συνεξάγονθ᾽ ἅμα καὶ τὸ σύμφυτον θερμόν. καὶ ταῦτα μὲν διὰ τὰς εἰρημένας αἰτίας, τὰ ἀπαράβλαστα καὶ μονοφυῆ ἀσυμμετρίᾳ τινὶ τοῦ θερμοῦ καὶ ὑγροῦ. δέχεται δὲ τὰς ἄλλας ἃ δύναται τηρεῖν τὴν ὑγρότητα καὶ θερμότητα τὴν ξύμφυτον, ὥστε βλαστάνειν μὴ μόνον ἀπὸ παρασπάδος ἀλλ᾽ ἔνια καὶ ἀπὸ τῶν ἄκρων οἷον συκῆ καὶ ἄμπελος καὶ τῶν ἀκάρπων δὲ καὶ φιλύδρων ὥσπερ ἰτέα καὶ ἀκτὴ καὶ λεύκη καὶ αἴγειρος. καθόλου μὲν οὖν καὶ τύπῳ τοῦτον διωρίσθω τὸν τρόπον.
